Validate tight-fit layouts where kerf deductions can change whether parts place correctly on available sheets.
Saw-Blade-Aware Planning
Kerf Cutting Optimizer for Saw-Blade-Aware Cut Lists
Kerf is the width of material removed by a cut. CutOps reserves that space when arranging rectangular parts, while keeping the finished part dimensions you entered unchanged.
Open the 3 mm kerf example to see the stock, parts, and result together. Then enter the measured cutting width for your own tool, rerun, and check any unplaced parts before exporting. The example is free and does not require an account.
Some features are available only on paid plans.
Account for Every Cut Before Production
Adding part areas is not enough to prove a job fits. The space between parts, their orientation, and the available sheet dimensions also matter. Use the actual cutting width before optimization so you review a layout with the same kerf assumption you will use on the saw.
Keep Finished Sizes and Cutting Loss Separate
Enter finished part sizes in the parts table and the cutting width in the kerf setting. Do not reduce each part by the kerf or add it to every part dimension yourself; that would change the requested job or count the allowance twice.
Keep kerf, per-part rotation locks, and material and grain settings aligned with the job. Recalculate after changing kerf and review both placed and unplaced parts.
What a 3 mm Kerf Changes
The example contains one 2440 x 1220 mm sheet, six 600 x 400 mm parts, and two 1000 x 300 mm parts. Two 600 mm parts beside one another need at least 600 + 3 + 600 = 1203 mm across the sheet, before edge trim or any additional cut.
Against the 1220 mm sheet width, that leaves 17 mm before those extra allowances. A zero-kerf calculation would show 20 mm instead. The checked example places all eight parts on one sheet at 68.5% utilization. This is a demonstration, not a promise about waste or the best layout for your job.
Where Accurate Kerf Setup Matters
Measure before planning
Use the measured cutting width for the installed blade and material, rather than assuming the blade body thickness is the kerf.
Re-run validation after tool changes
Update kerf values when blade configuration changes and re-check yield and placement before committing material.

Kerf Setup Questions
What is kerf in cut optimization?
Kerf is the material width removed by the blade during each cut. If kerf is ignored or underestimated, final part fit and layout feasibility can be inaccurate.
Can CutOps optimize layouts with kerf enabled?
Yes. Kerf is a configurable input in the free workflow. CutOps keeps the nominal part dimensions and reserves space for the cut in the layout. Enter the cutting width measured for your tool and material in the project unit.
Should kerf settings be reviewed before export?
Yes. A quick kerf check before final export is a practical quality-control step that helps prevent avoidable downstream recuts.
Can I start with the free CutOps plan for this workflow?
Yes. You can start with core layout planning in your browser and review the result before cutting.
Can I share this layout with teammates or production?
Yes. CutOps supports PDF and PNG for visual handoff plus CSV and JSON for structured downstream use.
