Cutting plan
How to read the plan
- Each row is one stock bar, drawn to scale and cut from left to right. Big number = length in mm, small text = part mark.
- Coloured pieces are halves of spliced parts. E3·a and E3·b have the same colour and are joined into one part, even when they come from different bars.
- Hatched = offcut. Grey is long enough to keep for reuse; red is waste.
- ×4The same cut on 4 bars. Only bars without splices are grouped; bars with splices are listed one by one.
Splices are structural details. The optimizer only decides lengths. Where a splice is allowed, its position and its welded or bolted detail must be checked and approved by the structural engineer.
- Fit rule: the parts in one bar plus one kerf between each pair of neighbours must not exceed the stock length. Reduce the stock length if bar ends need trimming.
- Waste is everything bought but not used as a part: kerf losses and offcuts shorter than the reusable limit. Longer offcuts are shown separately.
- Check: each plan is verified after it is built: every part is cut to its exact length, no bar exceeds the stock length, and every splice keeps your limits.
- Plans are near-optimal, not guaranteed optimal. The lower bound shown is total part length divided by stock length.
