The method behind the calculation
Assumptions and limits
Straight and rotated strip layouts are compared. Gaps apply between pieces; edge trimming is excluded. This is a layout suggestion, not a guaranteed optimum, guillotine cutting sequence or machine toolpath. Unused area includes cutting gaps. Material cost includes unused positions on the last sheet.
Follow the example calculation.
For a 2,440 × 1,220 mm sheet and 600 × 400 mm pieces with a 3 mm cutting gap, this layout fits 12 pieces. Producing 120 pieces needs 10 sheets. At 900 per sheet, total material cost is 9,000, or 75 per required piece.
Frequently asked questions
Is the cutting gap the same as edge trimming?
No. The entered gap is between pieces. If the sheet also requires edge trimming, reduce the usable sheet dimensions accordingly before entering them.
How do I preserve grain direction?
Choose “Keep grain direction” under 90° rotation. Pieces then stay in the entered orientation. The piece count may differ from a layout that allows rotation.
Can this plan go directly to a cutting machine?
No. This is a geometric layout suggestion. Guillotine cut order, toolpaths, machine constraints and remnant reuse are not modelled. The production team must verify the cutting sequence separately.
