Cutting Plan
Share tool
Only this public address is included. Your files, inputs and results stay out of the link.
Arrange required pieces on boards or linear stock. Include saw kerf, material quantities, grain direction and permitted rotation in the plan.

A visual example
The saw cut also uses material
Two 400 mm pieces need more than 800 mm of stock when the kerf is 3 mm. The remainder determines whether another cut is needed.
1,000 mm stock: two cuts Material use Length Two pieces 800 mm Two saw cuts 6 mm Remainder 194 mm Total 1,000 mm 1,000 mm stock: two cuts
Each 400 mm piece is separated. Two 3 mm cuts leave a 194 mm remainder.
803 mm stock: one cut Material use Length Two pieces 800 mm One saw cut 3 mm Remainder 0 mm Total 803 mm 803 mm stock: one cut
One 3 mm cut separates the two exact 400 mm pieces. The second piece ends at the stock edge, leaving no remainder.
Enter the real kerf and inspect the actual cut sequence, not just the sum of the piece lengths.
Illustrative example. This one-dimensional example assumes usable stock with the stated dimensions. The planner uses a bounded heuristic and does not guarantee the globally optimal plan. Check the plan before cutting.
How to use it
- Choose 1D bars or 2D sheets and enter available stock and required parts in millimetres.
- Set quantities, saw kerf, rotation permissions and grain direction; mark existing offcuts.
- Review placements, the cut sequence, reusable remnants and any unplaced parts.
- Export the checked plan as PDF, CSV or JSON.
A 1,000 mm bar with two 400 mm pieces and two 3 mm cuts leaves 194 mm. If the stock is exactly 803 mm, only one cut is needed between the two pieces.
Details & limits
Bounded 1D/2D guillotine heuristic, up to 200 parts. Dimensions use 0.1 mm precision. Full kerf stays inside stock. Every placement is checked; global optimality is not promised.
Is the layout guaranteed to use the least material?
No. It uses a bounded guillotine-cut heuristic and checks dimensions, quantities, grain and kerf. Unplaced parts stay visible, including cases where a different layout might work. Review the cut sequence and measurements before cutting; the diagram is a plan, not machine instructions.
