Cracks often start at the entry or exit point of a cut because that is where the heat dwells the longest.
Worn electrodes or nozzles cause erratic arcs, leading to inconsistent heat and increased stress on the material. CUMIC Steel Are you experiencing cracks on a specific material thickness or type, such as AR400/500 wear plate? Sheetcam Tutorial 7: Start Points
Optimizing SheetCam Parameters to Mitigate Hot Cracking in CNC Thermal Cutting
: Using longer or specialized lead-ins moves the initial high-heat "pierce" point away from the actual part geometry. This prevents the "hot spot" from causing a micro-crack at the edge of your finished piece .
