A complete 6000 mm aluminum profile cutting plan
This reproducible demonstration uses 6000 mm stock, 3 mm kerf and 8 mm trim per end. Its verified baseline result uses four stock bars with 94.4% material utilization. It is an example task, not a customer savings claim.
How kerf and end trim change a cutting plan
Kerf is the material removed by the blade. End trim reserves unusable material at the ends of a stock bar. Both must be included before a pattern can be called executable.
What is one-dimensional cutting stock optimization?
1D cutting stock optimization assigns required part lengths to available stock bars while minimizing material cost, stock count or waste. Width and shape are fixed; length is the dimension being optimized.
Call the Cutwise API with cURL, Python or JavaScript
The API uses the same solver-v1 request and result model as the browser calculator. Keep API keys on the server, set an explicit timeout and do not automatically retry an uncertain solve response.
Cutting optimization for steel tube, bar and profile stock
Turn a mixed demand list into repeatable cutting patterns while respecting available stock lengths, quantities, kerf and end trim. The result stays a planning aid that operators can verify before production.
What “proven optimal” and “feasible” mean in a cutting plan
OPTIMAL means the solver found a valid plan and proved no better plan exists for the submitted mathematical model and objective. FEASIBLE means the plan is valid, but the proof of optimality was not completed.
Maintained with substantive updates
We maintain these guides as product behavior, process explanations and reproducible examples evolve. An updated date marks a substantive change to the article; it is not a promise of a fixed publishing schedule.
September 12, 2026: the kerf guide now explains the exact cut-count convention and a hand-checkable capacity boundary, with a complete Chinese edition. The aluminum example adds the material balance and explains what its optimal result proves.
