Sheetcam Hot Crack ((new)) Direct

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

Implement Path Rules in SheetCam to slow the torch down or shut the air/plasma off a fraction of a second early (the "End of Cut" rule).

While often associated with the welding process, hot cracking in the context of SheetCam and CNC plasma cutting refers to the structural failure or "tearing" of the metal during or immediately after the thermal cycle of the cut. sheetcam hot crack

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.

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 Ensure your Pierce Delay is perfect

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.

Use SheetCam to create longer, curved lead-ins . This allows the pierce (the hottest part of the process) to happen further away from the finished edge. If you cut all the small holes in

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
