Sheetcam: Hot Crack Hot!

While "hot crack" is not a built-in "one-click" feature in SheetCam, users typically implement features to prevent cracking or heat-related defects (like "hot cracking" in welding or thermal stress in plasma cutting) through specialized tool path strategies.

The "hot crack" issue highlights the necessity of the CAM programmer’s expertise. A perfectly generated SheetCam file can still result in cracking if the gas pressure sheetcam hot crack

Torch Height Control (THC): Improper torch height can cause excessive heat buildup. SheetCam includes "Cut Rules" to disable THC during tight corners or lead-ins, preventing "torch dives" that could damage the material or cause thermal stress leading to cracks.
