Sheetcam Hot Crack [exclusive] May 2026

Implement Path Rules in SheetCam to slow the torch down or shut the air/plasma off a fraction of a second early (the "End of Cut" rule).

Ensure your Tool Library in SheetCam is calibrated to your plasma cutter’s manual. You want the fastest travel speed possible that still maintains a clean cut. The faster the torch moves, the narrower the HAZ and the less time the metal spends in that "danger zone" where cracking occurs. Material Considerations sheetcam hot crack

While often associated with the welding process, hot cracking in the context of SheetCam and CNC plasma cutting refers to the structural failure or "tearing" of the metal during or immediately after the thermal cycle of the cut. Implement Path Rules in SheetCam to slow the
