Sheetcam Hot Crack !full! Page
Cracks often start at the entry or exit point of a cut because that is where the heat dwells the longest.
Use SheetCam’s Optimization settings. Instead of cutting the "closest next" part, you can manually sequence the cuts or use a "keep cool" strategy. By jumping the torch to different areas of the sheet, you allow the material to dissipate heat, keeping the overall temperature of the HAZ below the critical cracking threshold. 4.

Ensure your Pierce Delay is perfect. A delay that is too short causes the torch to move before the metal is molten, creating mechanical stress; a delay too long creates a massive heat "puddle." Conclusion Cracks often start at the entry or exit
If you’ve been running a CNC plasma table for a while, you’ve likely encountered a few "ghosts in the machine"—those frustrating cut quality issues that seem to appear out of nowhere. One of the more technical challenges operators face is . By jumping the torch to different areas of
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
Cutting too slowly is a leading cause of hot cracking because it dumps excessive heat into the workpiece.
