Sheet Cut List Optimiser

Arrange rectangular parts on identical sheets using the trim, saw kerf and rotation rules you enter. The result is one possible layout and may not use the fewest sheets.

Dimensions are finished part sizes. Add machining or edge allowances to the part dimensions before calculating.

Parts list

Larger parts are placed first. The saw kerf you enter is allowed for between adjacent parts. The same entries always produce the same layout, but another arrangement may use fewer sheets.

Sheet 1 of 1 · diagram scales entered rectangles; use it as a planning map, not a cutting order.

The diagram shows sheet 1. The sheet and placed-part totals cover the full result. Check grain or face direction, defects, clamping and cut sequence separately.

  • 2440 × 1220 mm sheet; 10 mm edge trim; 3.2 mm kerf.
  • Rotation allowed; 2 Side parts and 3 Shelf parts.

How to use this cutting list

  1. Confirm the actual sheet size and any damaged or unusable edge.
  2. Enter finished rectangular part sizes plus any machining allowance you need.
  3. Allow rotation only when the face, pattern or grain direction permits it.
  4. Use the layout to test quantity and rough placement, then choose a cutting sequence that matches your equipment and support method.

The layout does not model clamps, blade entry, support, grain matching, defects or tool reach. It is one workable arrangement, not proof that no tighter one exists.

What the layout includes

It places rectangles on identical sheets using one saw kerf and one edge trim. Curves, angled parts, mixed stock sizes and saved offcuts are not included, so check those separately before buying or cutting.
