Sheetcam Hot Crack ((exclusive)) »

"SheetCam hot crack" issues are usually a combination of metallurgy and machine parameters. By leveraging , Path Rules , and Smart Sequencing , you can minimize the thermal stress placed on your parts.

Hot cracking (also known as solidification cracking) occurs when the metal reaches its melting point and begins to cool. If the metal is under high tension while it is in a "mushy" state (partially solid, partially liquid), the grains of the metal pull apart, creating a fracture. sheetcam hot crack

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). "SheetCam hot crack" issues are usually a combination

Use a "Leadin Type" of Arc in your operation settings. This provides a smoother transition for the plasma arc, reducing the sudden thermal shock to the boundary layer of the part. 2. Path Rules and "Overburn" If the metal is under high tension while

Use SheetCam to program a "pre-heat" or use specific path rules that avoid sharp 90-degree corners, which act as stress concentrators.
