Panel furniture manufacturing workflow in eight stages
For modular kitchens, wardrobes, hotel furniture and other project-based interiors, production is most reliable when every part has a defined route, a material identity and a quality checkpoint. Not every panel needs every stage; the route depends on its design, surface and hardware.
- Design and production planningConvert approved designs into a bill of materials, part lists, machining data and a production schedule.
- Material receiving and storageCheck board thickness and surface condition, then store panels safely under traceable material codes.
- Calibration and laminationWhere required, calibrate the substrate, apply adhesive and press the surface material.
- Panel cutting and nestingOptimise cutting patterns, cut boards into parts and track reusable offcuts.
- Edge banding and groovingApply, trim and finish the specified edge, and assign grooves to the right machining stage.
- CNC drilling and routingMachine hinge holes, dowel holes, connector positions, slots and profiles to approved drawings.
- Inspection and sortingConfirm dimensions, finish and machining, then sort parts by order, cabinet, room or dispatch.
- Assembly, packing and dispatchAssemble where required, protect parts, verify order completeness and ship with traceable labels.
Planning principle: size the complete production system to its bottleneck, not to the highest rated speed of a single machine. Allow for product mix, batch size, changeovers, operator availability and rework.
Machines used in modular furniture manufacturing
Each machine is selected from the parts it must process, not from its catalogue speed. Use this list to match every workflow stage to a machine category.
Panel saw and CNC beam saw
Cut rectangular parts from plywood, MDF and particle board. Choose loading, cutting height, optimisation and labelling to suit throughput and batch mix.
CNC nesting router
Cut shaped or irregular parts and, where suitable, combine cutting and machining in one set-up. Check hold-down, tooling and the real cycle time.
Edge banding machine
Apply and finish edges on straight panels. Consider edge material, panel size, glue system, surface protection and the finish quality you need.
CNC drilling machine
Drill accurate holes and grooves for hinges, shelves and connectors. Select 4- or 6-sided processing from your hole patterns and panel handling.
Wide-belt calibration sander
Bring substrates to a consistent thickness before surface processing, where the material and finish require calibration.
Glue spreader and press
Apply a compatible adhesive and laminate substrates using a validated pressure, temperature and cycle time for the material.
Material handling and storage
Use safe stack storage, lifting aids, conveyors and staging areas to cut unnecessary movement and protect surfaces.
Inspection, sorting and packing
Group traceable parts by order and destination so missing or faulty parts are found before packing, then choose flat-pack or assembled dispatch.
Standalone and connected panel production compared
Automation should follow a proven process. Start with accurate part data and stable machines, then connect material flow and software where volume and complexity justify the investment.
| Capability | Standalone production | Connected production |
|---|---|---|
| Job transfer | Operator selects and transfers each job | Validated job data sent digitally to each machine |
| Material movement | Manual handling or local conveyors | Integrated storage, buffers and transport where justified |
| Part traceability | Printed job sheets and local labels | Scannable part and order identity across every stage |
| Production control | Department-level progress checks | Manufacturing execution and live order status |
| Quality management | Operator checks and manual records | Defined checkpoints linked to each part's history |
Typical digital building blocks are CAD/CAM, cut-list optimisation, a manufacturing execution system (MES), enterprise resource planning (ERP), warehouse management, part labelling and machine interfaces. Interoperability must be verified for each system. For line sizing, see how to configure a cabinet making line and the smart factory guide.
How to engineer a project-based panel furniture factory
Hotel furniture, residential projects, kitchens and fitted wardrobes are rarely made in long runs. A project-based factory must handle small and medium series and batch-size-1 orders in the same shift. This guide sets out the engineering method that turns your parts data into department-by-department requirements, from raw panel receipt to the loading dock.
- Design basisMeasure demand in parts, boards, square metres and parts per minute.
- Part families and routesGroup parts by shape and size, and give every family a defined route.
- Department requirementsSpecify each machine group by size window, material, output and interfaces.
- Phased automation and validationBuild standalone machines ready for linking, then prove them with reference parts.
Step 1: build the design basis from your parts data
Use a representative export of real orders from your design software, not a catalogue estimate. A dataset of several months of projects shows the true mix of part sizes, materials, edge codes and batch sizes.
| Design-basis metric | How to calculate it | Why it matters |
|---|---|---|
| Net production minutes per shift | Shift hours × 60 × overall efficiency (for example 8 × 60 × 80% = 384 minutes) | Every department is sized to this time, not to the clock hours |
| Raw panels per shift | Planned board consumption, expressed in one reference size such as 2440 × 1220 mm (8 × 4 ft, about 2.98 m²) | Sizes the panel store, the handling equipment and the saws |
| Parts per board and m² per part | Total parts ÷ boards used; total part area ÷ total parts | Small average parts mean more handling, edging and labelling per board |
| Required parts per minute | Parts per shift ÷ net minutes | The rate every downstream department must sustain on accepted parts |
| Average quantity per unique design | Total parts ÷ number of unique part designs | Shows how much of your work is series and how much is batch-size-1 |
| Material and edge-code variety | Number of board, surface and edge combinations per batch | Drives stack strategy, edge magazine size and changeover time |
| Part-family distribution | Percentage of parts in each family (sides, tops, fronts, narrows, backs and others) | Decides how many edging and drilling cells of each type you need |
Required parts per minute = (raw panels per shift × parts per board) ÷ (shift hours × 60 × efficiency)
Design-basis calculator
Enter your own figures. The results update as you type and are planning estimates only.
- Net minutes per shift
- 384
- Parts per shift

- Required parts per minute
- 7.8
- Board area per shift (8 × 4 ft)
- 893 m²
- Average quantity per design
- 24
- Production character
- Small series
Each department, including edging, drilling, sorting and packing, must achieve the required parts per minute after changeovers, rework and inspection. Size the line to the slowest department.
Step 2: classify part families and give each one a route
Not every part needs every machine. Routing each family separately keeps fast lines fast and stops difficult parts from slowing the whole factory.
| Part family | Typical examples | Typical route |
|---|---|---|
| Wide carcass parts | Sides, tops, bottoms, fixed shelves | Rear-loading beam saw (stack cutting) → wide-part edge line with inline grooving → 4-sided CNC drilling → sorting |
| Fronts and visible parts | Shutters, drawer fronts, panels with handle grooves | Beam saw → flexible edge line with quick edge-code change → 6-sided CNC for hinge, handle and through-holes → sorting |
| Narrow parts (width up to about 120 mm) | Strips, rails, drawer sides, fillers, toe kicks | Cut as multi-part strips → separate into parts → narrow-part cross and length edge lines → CNC or edge drilling and dowelling → sorting |
| Thin parts (8 mm and below) | Back panels, drawer bottoms | Front-loading saw or a dedicated beam saw slot → usually no edging or drilling → direct to sorting or packing |
| Shaped parts | Curved tops, headboards, L-shaped corner parts | CNC nesting (single layer) → CNC contour edging and routing → manual sorting or the universal line |
| Thickened parts | Double-thickness tops, bed frames, headboard frames | Pre-drill single parts → screw or glue to double thickness → straight edge line or CNC contour edging → universal assembly and packing |
| Repair and express parts | Damaged, missing or urgent parts | Repair area: sliding table saw, single edge bander, single drilling CNC → re-enter the flow by scanning |
Define a narrow part by physical width before choosing machines. Wide-part edge banders can usually process narrow parts lengthwise only down to a stated minimum width, and crosswise only with suitable infeed support, so confirm these limits with the supplier.
Classify raw material stacks before you plan storage
| Stack type | Content | Typical use |
|---|---|---|
| A-stack | One material identity (one board, thickness and surface) | Series parts of a large project, cut in books for the highest saw output |
| B-stack | A few material identities, typically three or four | Mixed batches assembled from a storage rack in production order |
| C-stack (mixed stack) | Many material identities in one stack | Batch-size-1 and custom wardrobe work with high colour variety |
Storage normally grows in stages: floor stacks and a forklift, then rack storage to build B- and C-stacks overnight, then automated flat-panel storage with destacking, pre-labelling and transport to the saws once volume justifies it.
Step 3: department-by-department requirements
Open each department to see what to specify and the planning rules that most often decide whether the line meets its target.
Raw panel receipt, calibration and surface lamination
What to specify
- Incoming stack height, truck unloading method and a covered, level receiving area
- Separate storage for raw boards and for laminate sheets (HPL), protected from moisture and damage
- Calibration sander for unlaminated boards: working width, number of sanding units, belt speed control and segmented pressure for small or non-square parts
- Glue spreader for PVAc adhesive with top and bottom gluing, adjustable glue quantity and a lay-up table for placing laminates
- Press type, pressing area, daylight height, specific pressure and cycle time for each material combination
Planning rules
- A hot press suits large, repeatable laminating batches because its cycle is about one minute; a cold press suits special and small jobs but needs 30 to 40 minutes per pressed stack.
- Press both faces in a balanced sandwich so the panel stays flat.
- Allow for laminate overhang and remove it at the saw; agree the maximum overhang per side in advance.
- Confirm press pressure, temperature and cycle with your adhesive and laminate suppliers on your own boards.
Panel dividing: beam saws, front-loading saws and nesting
What to specify
- Raw panel and offcut size windows: minimum and maximum length, width, thickness and weight
- Carrier materials and densities (plywood, particle board, MDF) and their share of production
- Surfaces, including high-gloss or protective-film parts, black, structured and other scratch-sensitive finishes
- Output per shift for single-layer and for multi-layer (book) cutting, stated at your part mix
- Stack identity transfer (barcode scan first, electronic transfer later), optimisation software, offcut labelling and a second programme fence
- Waste removal: manual bins, a chipper or an underfloor conveyor
Planning rules
- Use rear-loading beam saws for thick panels in stacks, a front-loading saw for thin panels, offcuts and strips, nesting for shaped parts, and a sliding table saw for rework and 45° cuts.
- Expect output to vary widely, often by three times or more, between batch-size-1 single-layer cutting and series cutting in books.
- Raise efficiency by cutting standard high-quantity parts in advance for intermediate storage, adding look-ahead parts for later batches of the same material, and cutting narrow parts as multi-part strips.
- Record every reusable offcut with a label and location so it is cut before a new board is used.
- A typical production batch is several hundred to about 1,200 parts; it must be planned to keep edging and drilling busy, not only the saws.
Edge banding and grooving
What to specify
- Separate lines or machines for wide series parts, varied batch-size-1 parts, narrow parts crosswise, narrow parts lengthwise, and specials or repairs
- Part size windows, panel thickness range, edge materials and edge thickness range for each line
- Edge magazine size and automatic changeover, glue system (EVA, with PUR preparation if needed), and automatic resetting between thin and thick edges and profiles
- Infeed scanning, automatic resetting in the gap between parts, and return conveyors for second and third passes
- Inline grooving units with pneumatic jump-in and jump-out for stopped (sealed) grooves
Planning rules
- Cut back-panel and through grooves on the edge bander wherever the groove is within its reach, often up to about 30 mm from the edge, rather than on a CNC; this saves tooling cost and machining time.
- Do not use high-speed vacuum lifters or turners on protective-film or high-gloss parts at high cycle rates; the film can lift at the edge and spoil edge quality.
- Buy edge band in widths matched to panel thickness, with a small, controlled overhang top and bottom.
- Plan the edging sequence for integrated-handle parts: edge and groove the handle side first, then the opposite side, then the cross edges, then drill.
- Use a parallel milling and multi-grooving unit before edging long parts to prevent bowed edges and to pre-groove lengthwise.
CNC drilling, routing, shaped parts and inspection
What to specify
- 4-sided CNC drilling cells for the majority of standard parts, with independent heads and double-part processing for short parts
- 6-sided CNC centres for non-standard parts, through-holes, top and bottom routing and wide parts up to full board width
- A CNC contour edging and routing centre, or a 5-axis machine, for shaped parts
- Drilling spindle counts, grooving saws, routers and tool changers matched to your hole patterns
- Inline inspection of edges, hole positions and grooves, with an OK or not-OK signal to the line control
Planning rules
- 4-sided cells are often more than twice as fast as 6-sided machines, so route most parts to them and keep 6-sided capacity for parts that need it.
- Provide a balancing buffer in front of the drilling cells, and do not mix 4-sided and 6-sided parts in one buffer.
- Plan spare capacity on 6-sided machines, because the share of 6-sided parts changes from project to project.
- Rejected parts go to the repair area and re-enter the flow by scanning, so no order waits for a missing part.
Thickened parts and the repair and express area
What to specify
- Pre-drilling of single-thickness parts, electric screwing or gluing stations, and an edge route for the doubled part
- A sliding table saw with quick digital adjustment and 0 to 45° tilt
- A single straight edge bander and a contour edge bander with edge pre-heating as backup
- A manual trimming and scraping workbench
- A single drilling and dowelling CNC for very narrow parts, with barcode programme call-up
Planning rules
- Thickened parts can return to automatic sorting only if they have one straight edge in each direction, are close to rectangular and remain within the sorter's thickness limit.
- Standardise the dowel size so the repair area and the assembly line use the same one.
- Keep express work in this area so it never interrupts the main lines.
Sorting, intermediate storage and order kitting
What to specify
- Sorting method suited to your thickness range; shelf sorting handles a wide range better than robot sorting
- Sorting rate in and out at the same time, at least equal to the required parts per minute
- Sorting capacity of roughly two batches plus a 20 to 25% allowance for look-ahead parts
- Exit logic for flat packing, assembly and special parts
Planning rules
- Produce standard high-quantity parts first into a short-term intermediate store, then release special parts in batches of a few hundred to about 1,000.
- Kit each order on a cart with its special parts, its standard parts from intermediate storage and bought-in items such as hardware, runners, corner protectors and lighting.
- Empty a sorting tower before switching it between packing and assembly logic; urgent special parts can be released whenever there is a gap.
Flat packing
What to specify
- Manual or robot stacking, maximum stack height and the zero line in length, width and height
- Carton cutting to measured size, closing, sealing and strapping
- A packing terminal showing live pack logic for each packet
Planning rules
- Robot stacking needs data for each part: layer sequence, part sequence, orientation and X, Y and Z position, supplied by the MES or packing software.
- Align the stacking orientation with the downstream carton line.
Carcass assembly and the universal line
What to specify
- Station sequence: lay-up and runner fitting, pre-assembly, carcass clamp, back-panel nailing, case erecting or turning, hinge and lock fitting, front fitting, drawer press, final inspection, carton cutting, packing and strapping
- Carcass clamp size window, number of clamping jaws, working height and automatic reset from the carcass identity
- Through-feed horizontal drilling and dowelling for tops, bottoms and shelves
- A separate universal line for special, shaped and electrically fitted products
Planning rules
- Prepare drawers and fronts first; start carcass assembly only when they are complete.
- Call up carcass parts in assembly order: sides, horizontal panels, narrow strips, fronts and drawers, then backs.
- Plan the clamp cycle, typically 60 to 90 seconds including pressing, against the required carcasses per shift and the glue's open and pressing times.
- Use the universal line for headboards, complex shapes and urgent replacements so the main line runs undisturbed.
Dispatch and loading docks
What to specify
- Number of loading bays from your daily truck plan and packet volume
- Dock height matched to the truck bed (often about 1,000 to 1,200 mm in India), with a dock leveller where truck heights vary
- Covered loading inside the building to protect packets from rain
- Staging space for completed orders, checked against the packing list before loading
Step 4: phase the automation
Begin with standalone machines that are prepared for linking. Connect them only after the process, data and output are stable.
| Department | Phase 1: standalone, ready for linking | Phase 2: connected |
|---|---|---|
| Panel storage | Floor stacks and racks; mixed stacks built manually or overnight | Automated flat-panel storage, destacking, pre-labelling and transport to saws |
| Cutting | Barcode scan of stack identity; labels printed after cutting; manual part removal | Electronic stack identity transfer; pre-labelled boards; scanned infeed to automatic distribution |
| Saw to edging | Roller tracks and staff distributing parts by barcode | Automatic transport with buffers for wide, narrow, special and offcut parts |
| Edging to drilling | Manual transfer to drilling cells | Automatic transfer with separate 4-sided and 6-sided buffers, bypass for undrilled parts and inline inspection |
| Sorting and packing | Intermediate stock, kitting carts and manual stacking | Automatic shelf sorter, robot stacking and carton cutting |
| Assembly | Cart-fed assembly with scanned completion reports | MES-sequenced part release, automatic clamp reset and dedicated carton cutting |
Part labelling and data interfaces
What each part label should carry
- Order or project identity and part family
- Edge code and edge thickness for each of the four sides
- Cutting size and finished size after edging
- Substrate thickness and surface identity
- A unique part identity as a QR or Data Matrix code, printed large enough to scan reliably (about 35 × 35 mm on a label of about 40 × 100 mm)
Data each machine needs
- Stack identity at the saw and part identity at every infeed scanner
- Programme call-up for edging, drilling and assembly from the part or carcass identity
- OK or not-OK signal from inspection to the line control
- Sort, pack and assembly logic, including stack sequence and part positions
- Completion reports for kits, drawers, fronts and carcasses back to the MES
Plan exceptions in advance: very narrow parts cannot carry a full label, and veneered or scratch-sensitive surfaces may need an alternative identification method. Interfaces between the MES, optimisation software and each machine must be confirmed in writing by every supplier.
What a machine technical specification should state
Use this checklist to compare suppliers on the same basis. A quotation that cannot answer these points is not yet ready to be compared.
| Item | What to define |
|---|---|
| Part size window | Minimum and maximum length, width and thickness, physical infeed direction and weight |
| Materials | Carrier materials and densities, surfaces, sensitive finishes and permitted overhang |
| Output | Accepted parts per shift at your stated part mix and batch size, not catalogue feed speed |
| Process units | Each working unit, its function and its automatic resetting |
| Handling | Infeed, outfeed, return, buffers and protection of sensitive surfaces |
| Data interfaces | Scanning, programme call-up, labelling and signals to and from the MES |
| Waste and utilities | Waste removal, dust extraction, compressed air and electrical load |
| Staffing | Operators and helpers per shift in each phase |
| Reference parts | A defined set of real parts from your orders for each machine group |
| Acceptance test | Output, quality and tolerance targets proven on the reference parts before final payment |
Validation principle: agree the reference parts before ordering and prove each department on them at installation. Figures in this guide are indicative planning values; the capacities, cycle times and interfaces for your factory are confirmed in a written, project-specific proposal.

Financial decision-making before investing in a factory, machine or feature
Five of the thirty rules of thumb that furniture and door manufacturers can use to judge demand, cash flow, cost and bankability before committing capital.
Golden principle: invest in what improves safety, quality, profitability and cash flow, not merely in greater capacity, more automation or additional features.
- Demand before capacity. Establish realistic customer demand before deciding the factory size or buying machines.
- Cash flow before profit. A profitable factory can still fail if cash is locked in stock, receivables and debt repayments.
- Find the bottleneck first. Invest where the current process constrains saleable production, quality or delivery.
- Compare cost per good part, not machine price. Include labour, material, rejection, electricity, tooling, maintenance and downtime.
- Check the EMI against cash flow. Debt repayments must remain affordable even when sales fall or collections are delayed.
Board gross profit calculator
Check what extra output is worth before you invest. The example uses an 8 ft × 4 ft board (32 sq ft), 15.6% wastage and a gross profit of ₹100 per saleable sq ft; enter your own figures.
Board length (ft)8
Board width (ft)4
Wastage (%)15.6
Cost per sq ft (₹)200
Sales price per sq ft (₹)300
Extra boards per shift10
Shifts per day1
Working days per year300
Board area32 sq ft
Net saleable area per board27 sq ft
Gross profit per sq ft₹100
Gross profit per board₹2,700
Gross profit per day₹27,000
Gross profit per year₹81 lakh
Formula: net saleable area = board area × (1 − wastage %), rounded to 0.1 sq ft; gross profit per sq ft = sales price − cost; yearly gross profit = gross profit per board × extra boards per shift × shifts × working days. The example figures are illustrative. Caple can work out the numbers for your factory.
Six-step factory investment checklist
- Define demandRecord orders by product family, unique design, quantity, board type and delivery window. Separate repeat orders from one-off custom work.
- Calculate usable capacityEstimate accepted parts per shift after breaks, utilisation, changeovers and inspection. Balance cutting, edging and drilling.
- Design safe material flowMap receiving, storage, production, sorting and dispatch. Reserve space for service access, dust extraction, fire safety and expansion.
- Validate utilitiesSpecify electrical capacity and power quality, compressed-air quality, dust extraction, lighting and housekeeping.
- Estimate the full investmentInclude machines, installation, tooling, utilities, software, training, handling equipment and working capital, not the machine price alone.
- Check operating economicsCompare cost per saleable part, quality losses, labour, energy, maintenance, inventory, cash conversion and loan affordability.
Decision order: health and safety → quality → productivity → operating cost → profitability → return on investment. A feature is worth buying only when it gives a measurable improvement in your application.

Before Caple can propose a panel furniture line, we need a clear requirements list covering six areas: general requirements, raw materials warehouse, sizing, edge banding, drilling and sorting. Each answer below explains what to provide and why it matters. Use it to prepare your enquiry, then send the requirements template.
General requirements
What product types should I list in my project requirements?
List every product family you plan to make, for example kitchen cabinets, wardrobes, cabinet doors and shutters, office furniture, hotel furniture or bathroom vanities. Product type decides the part families, hardware drilling and edge types, so a factory making shutters needs a different edging and drilling mix from one making only carcasses.
Which processes should the line include?
State each process you need inside the project scope: raw panel storage, sizing (cutting), edge banding, drilling, sorting, assembly and packing. Also say which processes stay outside the line, such as lamination, finishing or outsourced work, so the material flow and interfaces are planned correctly.
How should I state the target capacity?
Give three linked figures: capacity in pieces per minute, single-shift capacity in pieces per shift, and single-shift duration in hours. Pieces per minute = pieces per shift ÷ (shift hours × 60 × efficiency). Every department, not just the saw, must reach this rate on accepted parts.
What raw material information is needed?
Give the board type (particle board, MDF, plywood or other), the surface (melamine, HPL, paper foil, veneer, high gloss with protective film or unlaminated) and the board dimensions, for example 2440 × 1220 × 18 mm. Note any scratch-sensitive surfaces, because they change handling, edging and labelling.
Why are minimum and maximum workpiece sizes so important?
The smallest and largest part length, width and thickness define the size window every machine, conveyor, buffer and sorter must handle. One very small or very large part outside the window can force a manual route, so list the extremes and how often they occur.
Is my factory mass batch, batch-size-1 or mixed production?
Mass batch means many identical parts cut in stacks; batch-size-1 means each part is unique to an order; most project and custom furniture factories are mixed. Production mode decides saw type, edge-code changeover, software and how much sorting you need.
What space information should I provide?
Give the usable length, width and clear height of the building, the position of columns, doors and loading docks, and any area reserved for expansion. Height matters for storage systems, mezzanines and overhead conveyors.
Do I need to send a layout drawing?
A rough layout sketch helps, even hand-drawn, showing where material arrives and where finished goods leave. Caple then proposes a machine layout that keeps the material flow short and leaves room for service access, dust extraction and future automation.
Raw materials warehouse
Which raw panel storage type suits my factory?
Flat (floor or single-level) storage is simplest and suits lower volumes. A stereoscopic, multi-level automatic storage system suits high volume and many board types, building mixed stacks for batch-size-1 cutting. Choose by board variety, daily board consumption and available height.
What panel sizes and stacking quantities should I list?
List each board size with its thickness and the number of stacks or boards stored, for example two stacks of 3000 × 2100 × 18 mm. This sizes the storage area, gantry or crane capacity and stack height.
How many loading and unloading bays does the warehouse need?
State how many truck receiving positions and how many outfeed positions to the saws you need. This depends on deliveries per day, number of saws fed and whether boards are restocked during production.
Which machines should the warehouse connect to?
List the saws, nesting machines or other stations the store will feed automatically. Each connection needs a transfer method, a stack identity and agreed signals between the store control and the machine.
What data file does the warehouse need?
Most stores read stock and job data from a CSV or XML file produced by your design or optimisation software. Confirm the file format, the fields (material code, board size, quantity and job number) and how often it is exchanged.
Sizing (panel cutting)
Should I choose a panel saw or a nesting machine for sizing?
A beam (panel) saw is fastest for rectangular parts and can cut stacks of boards. A CNC nesting machine cuts shaped parts and can drill, groove and route in the same set-up, but cuts one board at a time. Many project factories use both.
What should I specify about the main cutting machine?
State the machine type, the preferred model or capacity class, and the configuration: cutting length, saw blade projection (stack height), loading table, optimisation software and label printer. Caple then matches a model to your output.
How will the cutting line be connected, fed and unloaded?
Describe the connecting method (standalone, conveyor-linked or connected to storage), the feed-in method (manual, lifting table, rear loading from storage) and the feed-out method (manual removal, outfeed conveyor or automatic transfer to edging).
Which processing types are needed at the cutting stage?
List whether the stage only sizes parts or also drills, grooves or routes them. Combining operations on a nesting machine reduces handling, while separate machines usually give more output for rectangular parts.
How should offcuts be managed?
Decide whether reusable offcuts are labelled, stored in a rack and recalled by the optimisation software, or scrapped. A managed offcut store saves board cost but needs labels, locations and discipline.
What processing data does the cutting machine need?
Saws usually read cutting patterns from optimisation software, for example cutting-list or programme files; nesting machines read CNC programmes or XML exports from design software. Confirm the exact file format each machine accepts.
Edge banding
Which type of edge banding machine do I need?
Choose between single-sided edge banders, double-sided edge banders and dedicated door or shutter edge banders. Single-sided machines are flexible; double-sided machines edge two opposite sides in one pass for higher output; door edge banders handle fronts and special profiles.
What edge bander configuration should I specify?
State edge thickness range, glue type (EVA or PUR), number of edge magazines and automatic changeover, corner rounding, scraping, grooving and buffing units, and the panel thickness range.
How is the edge banding line connected, fed and unloaded?
Describe whether parts are fed manually, by an infeed conveyor or by automatic transfer from the saw, how they return for the next side, and whether they leave to a stack, a conveyor or the drilling stage.
What edging sequence should I state?
State whether the long sides or the short sides are edged first, or another sequence. The sequence affects edge quality at corners, return conveyor design and line output, and parts with handle grooves often need a special order.
What edge banding data is needed?
Edge banders with automatic changeover read edge codes and settings from a CSV or XML file, or from a label scanned at the infeed. Confirm the data format and which fields set the edge material, thickness and grooves.
Drilling
Which drilling machine type suits my parts?
A 6-sided CNC drilling machine processes all faces in one pass and suits batch-size-1 and fronts. Through-feed drilling machines are faster for standard carcass parts in series. Point-to-point CNC machines add routing and grooving.
What drilling machine configuration should I specify?
State part size range, number of vertical and horizontal drilling spindles, grooving saws, routing spindles and tool changer, and whether two parts can be processed at once.
How is the drilling line connected, fed and unloaded?
Describe whether parts arrive manually, by conveyor from edging or through a buffer, and whether they leave to stacks, sorting or assembly. Separate buffers for different drilling machines help balance the line.
Which drilling data formats should be confirmed?
CNC drilling machines read programme files such as MPR, BAN, PTX or SCX, or XML exports from design software, depending on the machine control. Confirm the format with your software and the machine before ordering.
Sorting
Which sorting type should I choose?
Flat (shelf) sorting handles a wide range of part sizes and thicknesses; robot sorting suits higher volumes of parts with a narrower size range; manual sorting with carts suits lower volumes. Choose by parts per batch, size range and labour cost.
What sorting logic should I define?
Define how parts are grouped on leaving the sorter: by order, cabinet, room, packet or assembly sequence. The logic must match how your assembly and packing teams work.
How do I decide the maximum board quantity per batch?
State the largest number of boards, or parts, in one production batch. The sorter must hold at least one complete batch, and usually more, so that one batch can be loaded while the previous one is released.
How are parts fed into and taken out of the sorter?
Describe whether parts arrive manually or by conveyor from drilling, and whether they leave to carts, stacks, a packing line or an assembly line.
What sorting data is needed?
The sorter needs each part's identity, its order and packet, and its position in the sequence, usually from a CSV or XML export of the design or MES software. Confirm the format and how labels are scanned.
Frequently asked questions
What machines do I need to manufacture 200 flush doors per shift?
A typical 200-door-per-shift line, sized against your door specification, requires a cross-cut saw, straight-line rip saw, 4-side moulder, panel or beam saw, cold press for frame assembly, wide-belt calibration sander, hot press for veneer or HPL pressing, through-feed edge bander, multi-boring machine or CNC router for lock and hinge cut-outs, and a finishing line (UV for flat leaves). Caple can propose these as one package after reviewing your door specification.
What is the difference between a door leaf, a door jamb and an architrave?
The door leaf is the moving panel of the door. The door jamb is the fixed frame inside the wall opening that the leaf hinges from, with a finished section of 100 × 45 mm. The architrave is the decorative moulding that covers the joint between the jamb and the wall, with a finished section of 60 × 18 mm at the front and 25 × 18 mm at the back. Jambs and architraves can be made from solid wood or from finger-jointed board, LVL or HDF wrapped with veneer or PVC foil.
Can the same factory make both flush doors and solid wood panel doors?
Yes, many door factories do. The two routes can share sanding and finishing resources, and sometimes the panel saw, depending on the product mix. They diverge at the core: a flush door uses a cold-pressed softwood frame with a tubular core and MDF skins, while a solid wood panel door uses profiled stiles and rails with an MDF centre panel. The charts on this page are based on indicative capacities of 200 flush door leaves and 25 solid wood panel doors per shift.
What edge-banding thickness should I plan for?
Typically up to 2 mm in rolls and up to 12 mm in strips, depending on the edge bander model; always check the machine specification for your edge material. Confirm with Caple whether the model you choose handles both rolls and strips at your panel thickness. Choose the glue system too: EVA hot-melt suits most interior work, while PUR gives a thinner, more moisture- and heat-resistant joint but needs a compatible glue unit and cleaning routine. Add a curvilinear edge bander for curved or arched panels.
Why is UV recommended for door-leaf finishing?
UV roller coating typically cures within seconds under UV lamps and, with a suitable coating system, can give a hard, scratch-resistant film. On a correctly sized line it can finish around 200 flat leaves a shift (indicative) with little curing-rack space. Output and film properties depend on the line length, lamp configuration, coating system and supplier data. Flat-line roller coating is not suited to complex profiles, so jambs, architraves and panel-door rails are usually spray-finished with PU, NC or another specified lacquer system.
What is the correct sequence for making modular furniture?
Most panel-based projects follow design and part-list preparation, material receiving, optional lamination, panel cutting, edge banding, CNC drilling or routing, inspection, sorting, assembly and packing. A part skips any stage it does not need.
How do I choose between a panel saw, a CNC beam saw and a nesting router?
Compare your board sizes, part shapes, volume, batch sizes, edge requirements and the capacity of the downstream machines. Rectangular parts usually suit a panel saw or beam saw, while shaped parts often suit nesting. Verify cycle time on representative jobs.
What determines edge banding machine capacity?
Capacity depends on feed speed, panel length, gap between panels, number of edges per part, set-up changes, material handling, glue system and the quality you accept. Measure accepted parts per shift, not feed speed alone.
Should I automate my complete factory at the start?
Not necessarily. First establish demand, clean production data, a stable process and a safe layout. Choose modular upgrades so later automation can remove proven bottlenecks without replacing sound equipment early.
How does part tracking help project-based furniture production?
Consistent part labels and scan points connect cutting, edging, drilling, sorting and dispatch. This improves order visibility and makes missing parts easier to find, provided data entry and scanning are disciplined.
How do I estimate the return on investment of a furniture factory?
Build a conservative cash-flow model from accepted output, contribution per unit, fixed costs, labour, maintenance, material yield, loan repayments and working capital. Then test it against slower demand, delays and higher rejection.
What site conditions keep woodworking machines reliable?
Stable electrical supply with proper earthing, clean and dry compressed air, effective dust extraction, correct lubrication, sound raw material, quality consumables, trained operators and routine preventive maintenance.
How do I get a customised line proposal for my factory?
Send the ten details in the factory planning brief on this page: products, target output and mix, materials and sizes, drawings and data, shifts, factory area, utilities, automation level, budget and finance, and location. The Caple application team reviews them and replies with a machinery recommendation, followed by a proposal with a machine list, a CAD factory layout, an ROI calculation and finance or leasing options.

How do I size a project-based furniture factory?
Start from a representative export of real orders. Calculate net minutes per shift (shift hours × 60 × efficiency), raw panels per shift, parts per board and the required parts per minute. Then size every department, including edging, drilling, sorting and packing, to sustain that rate on accepted parts, and plan the line around the slowest department.
What is the difference between A-, B- and C-stacks in panel cutting?
An A-stack holds one material identity and is cut in books for the highest output. A B-stack mixes a few material identities, typically three or four, assembled in production order. A C-stack, or mixed stack, holds many material identities and suits batch-size-1 and custom wardrobe work.
Should grooves be cut on the edge bander or on the CNC?
Where the groove is within the edge bander's grooving reach, often up to about 30 mm from the edge, cutting it inline on the edge bander is usually faster and cheaper in tooling. Reserve CNC grooving for deeper, stopped or non-standard grooves that the edge bander cannot make.
Why use both 4-sided and 6-sided CNC drilling machines?
4-sided drilling cells are often more than twice as fast as 6-sided machines, and most carcass parts need only 4-sided processing. Route the majority of parts to 4-sided cells, keep spare 6-sided capacity for fronts and non-standard parts, and place a separate balancing buffer in front of each type.

Assumptions behind this guidance and disclaimer
Process charts, capacities and rules of thumb on this page are planning aids. They rest on the assumptions below.
- Shift basis: capacities are indicative for one 8-hour shift with planned breaks, trained operators and a stable product mix.
- Accepted output: real output is lower than a machine's rated speed because of changeovers, handling, maintenance and rejection, so lines are sized on accepted parts.
- Standard material: boards, solid wood, adhesives, edge materials and coatings are of consistent quality, size and moisture content.
- Utilities: stable power with proper earthing, clean dry compressed air and adequate dust extraction are available at each machine.
- Routing: not every part passes through every stage; each route follows its design, surface and hardware.
- Software and automation: data exchange between design software, machines and production systems is checked case by case before purchase.
- Finance: investment rules are general rules of thumb; prices, taxes, interest rates and subsidies change and must be checked at the time of decision.
Disclaimer: the information on this page is general guidance for planning and education. It is not a guarantee of capacity, quality, safety, legal, tax or financial outcome.
Capacity, cycle time, compatibility, safety provisions, utility needs and commercial results must be confirmed against your products, materials and site, and against the final written technical and commercial offer. Specifications may change without notice.
Always follow applicable safety, electrical, fire and environmental regulations and the manufacturer's instructions. Images, charts and videos are for illustration.
