Sheetcam - Hot Crack Fix

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.

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

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.

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

"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

If you’ve been running a CNC plasma table for a while, you’ve likely encountered a few "ghosts in the machine"—those frustrating cut quality issues that seem to appear out of nowhere. One of the more technical challenges operators face is .

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. Instead of cutting the "closest next" part, you

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.
