Kerf Width Reference

View kerf width estimates by material, thickness and nozzle, and approximate material loss.

Reference-matrix input: This lookup returns a starting kerf input from the internal matrix. Confirm the value with your machine cut chart, test coupon, and first-article inspection before using it in a production quote.

Last reviewed: 2026-04-27. Shop-measured kerf records, approved CAM compensation, and machine-specific cut charts should override this starting input when they are available.

Override Workflow

Use the lookup value only until you have stronger shop evidence. Replace it with a measured kerf value when the job has a current cut chart, measured coupon, CAM compensation record, or first-article inspection result.

  • Record material grade, thickness, nozzle, gas setup, focus, program feed, and machine ID.
  • Cut a coupon or use a controlled first article, then measure the actual cut width.
  • Update the quote input and CAM compensation after inspection approval.
