Cut list optimizer

Enter the sheet you will buy, the saw blade width (kerf) and your parts, one per line as name, length, width, quantity. Fractions work: Side, 36, 11 1/4, 2. The layout is drawn to scale with every part numbered, using the same optimizer as the Benchwise app.

How the optimizer works

Sheets are cut the way a table saw works: each cut runs all the way across what is left of the piece (a guillotine cut). The optimizer tries many strategies (sort order, where each part goes, how the leftover is split) and keeps the one that needs the fewest sheets, then the one that leaves the largest usable offcut. The saw kerf is counted for every cut, but not at the edge of the sheet.

Tips for a good cut list

• Measure the finished size of each part and add the kerf here rather than in the dimensions.
• Mark parts with visible grain or veneer so they are not turned.
• Cut the biggest parts first, and keep the offcuts: the optimizer shows the largest remnant of the last sheet.
• Add 5 to 10 percent for mistakes if the sheet is expensive, or if you need the same grain across parts.

The Benchwise app also optimizes boards (lumber cut along its length), several materials in one project, ten ready plans and prices for a buy list.
