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. Cutting Speed and Feed Rates

Here is a deep dive into why this happens and how you can use SheetCam’s powerful toolset to prevent it. What is Hot Cracking? sheetcam hot crack

In plasma cutting, this usually happens in the . Factors like high-carbon content, impurities in the metal (like sulfur or phosphorus), and extreme thermal stress contribute to the problem. How SheetCam Helps Prevent Hot Cracking Use SheetCam’s Optimization settings

Cracks often start at the entry or exit point of a cut because that is where the heat dwells the longest. In plasma cutting, this usually happens in the

Setting a small overburn (cutting slightly past the start point) ensures the metal is fully severed, preventing the mechanical "tearing" that happens when a part is forced out of the skeleton. 3. Heat Management through Cut Sequencing

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

If you cut all the small holes in one corner of a part consecutively, that area will become extremely hot, increasing the risk of hot cracking.
