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
Cracks often start at the entry or exit point of a cut because that is where the heat dwells the longest. sheetcam hot crack
When a torch finishes a closed loop (like a circle), it often leaves a small "divot" or a localized hot spot where the start and end meet. This is a prime location for a crack to propagate. Use SheetCam’s Optimization settings
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 This is a prime location for a crack to propagate
"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.
Remember: the goal is to get in, cut the metal, and get out before the heat has a chance to ruin the molecular integrity of your edge.
