Generate plan
Review stock usage, layout and waste.
Use cases
1D Cut Optimizer Online use cases
Use 1D cut optimizer workflows for real cutting jobs, not just a generic calculator screen.
Bars and rods
Group repeated bar and rod lengths into fewer stock pieces before cutting.
Pipes and tubes
Plan pipe, tube and profile cuts while accounting for blade or wheel kerf.
Linear profiles
Optimize strips, channels, rails and custom extrusion stock from fixed lengths.
Mixed stock lengths
Compare available stock sizes when a job can use more than one length.
Benefits
Plan before material reaches the saw
A clear linear cutting plan helps estimate stock requirements, reduce waste and avoid manual trial-and-error.

1D Cut Optimizer Online FAQs
Answers to common questions about this cutting workflow and material type.
What is a 1D cut optimizer?
A 1D cut optimizer plans cuts along one length of material, such as a bar, pipe, tube, rod or strip. It arranges required pieces into available stock lengths to reduce unused leftover material.
Can I use this for bars, pipes and tubes?
Yes. The generic optimizer is intended for linear stock including bars, pipes, tubes, rods, profiles, channels and strips.
Does kerf affect the cutting plan?
Yes. Kerf is the material lost between cuts because of the blade, saw, abrasive wheel or cutting tool. Including kerf makes the plan more realistic.
What happens if a piece is longer than the stock?
Oversized pieces should be listed as unplaced cuts so they are not hidden or silently dropped from the plan.
