Sheetcam Hot Crack ((full)) -
If your plasma cutter cannot adjust current on the fly, use SheetCam rules to turn off the Torch Height Control (THC) on corners to prevent the torch from diving into the molten pool due to voltage fluctuations. Fine-Tune Feed Rates and Tooling Parameters
In the realm of metal fabrication and welding engineering, the structural integrity of a final assembly is paramount. Among the various metallurgical defects that can compromise a workpiece, "hot cracking"—also known as solidification cracking—stands out as a particularly insidious issue. While the term "SheetCam" typically refers to a popular Computer-Aided Manufacturing (CAM) software used for CNC cutting, the phrase "SheetCam hot crack" colloquially refers to the occurrence of hot cracking in sheet metal components prepared via such software. This phenomenon occurs during the final stages of solidification in welding or thermal cutting and is influenced by a complex interplay of chemical composition, thermal management, and mechanical constraint. Understanding the mechanisms behind hot cracking is essential for fabricators to ensure the longevity and safety of their products. sheetcam hot crack
If the pierce delay in SheetCam is set longer than necessary, the torch sits stationary over the molten pool, transferring excessive thermal energy into the surrounding plate before the XY motion even begins. If your plasma cutter cannot adjust current on
What it does
Never pierce directly on the cut line of your finished part. While the term "SheetCam" typically refers to a
