Plan parts on sheet stock with saw kerf, edge trim, grain-aware rotation, unplaced-part warnings, and an exact cutting CSV.
Step by step
01Start with the real dimensions
Enter sheet width, sheet height, available quantity, blade kerf, and edge trim in millimetres. Turn off rotation when the part height must follow the sheet height or grain direction. Keep all dimensions in the same unit.
02Edit and inspect
Enter one part per line as name, width, height, and quantity, separated by commas, tabs, or semicolons. The planner expands quantities and compares three deterministic packing orders. It reports parts that do not fit the available stock.
03Export and verify
Inspect each sheet and download the placement CSV. Save project keeps the parts list and stock settings in a local JSON file you can reopen later. The PDF is a scaled reference diagram, not a cutting template. Use numeric dimensions, verify the stock, and plan a safe cut sequence before operating a saw.
Why this one
Real kerf consumes material
The kerf allowance is removed between neighboring placements. Edge trim is reserved on all four stock edges. These areas are excluded from usable placement space, so tightly fitting parts do not quietly share the same saw cut.
Guillotine packing
Each placement splits a free rectangle into a right-hand strip and a full-width lower remainder. Area, longest-side, and width-first ordering are compared. This is a practical deterministic heuristic rather than a proof of the mathematically optimal yield.
Unplaced parts remain visible
Parts that exceed the stock dimensions or available capacity remain in a separate list. A partial plan never pretends every requested piece was accommodated. The CSV retains placement coordinates, resulting dimensions, sheet number, and whether the piece was rotated.
FAQ
The wood cut layout planner saves the parts list, stock dimensions, kerf, trim, sheet count, and rotation setting in a local JSON project. Open project restores the inputs and recalculates the layout. Share links contain settings only.
The wood cut layout planner reserves the entered kerf between placements and also supports a separate edge-trim allowance.
Turn off Allow 90° rotation in the wood cut layout planner to keep every part’s height parallel to the sheet’s height.
The wood cut layout planner compares three guillotine packing orders. It provides a useful layout but does not guarantee the fewest theoretically possible sheets.
The wood cut layout planner PDF is scaled for reference. Use the numeric part dimensions and placement CSV rather than measuring the printout.
