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.
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 sheetcam hot crack
Understanding and Preventing "Hot Cracking" in SheetCam: A Guide for CNC Plasma Cutting Hot cracking (also known as solidification cracking) occurs
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 A delay that is too short causes the
