Sheetcam Hot Crack !new! -

In manufacturing and CNC plasma cutting, a hot crack (also known as a solidification shrinkage crack) refers to a fracture that occurs during the final stages of solidification in a weld or cut, typically caused by localized thermal stress. While SheetCam is a CAM software used to generate G-code, it does not have a specific "hot crack" feature; rather, it provides tools like Path Rules to mitigate the heat-related issues that lead to such defects.

For Thick Plate: 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 Incorrect cutting parameters : Improper settings for cutting

  1. Incorrect cutting parameters: Improper settings for cutting speed, amperage, or gas flow can lead to uneven heating and cooling of the material, causing cracks.
  2. Material properties: Certain materials are more prone to cracking due to their chemical composition, thermal conductivity, or microstructure.
  3. Inadequate cooling: Insufficient cooling or improper cooling techniques can cause the material to overheat, leading to thermal stress and cracking.
  4. Poor G-code programming: Errors in the G-code file generated by SheetCam can result in incorrect cutting paths or speeds, which may cause hot cracks.
