Sheetcam Hot Crack !!exclusive!!

Ensure your lead-in is long enough to keep the initial pierce puddle away from the final part edge. For thick materials, a lead-in of 6mm to 10mm (0.25" to 0.4") is recommended.

In your SheetCam tool definitions, look at your and Pierce Height .

Instead of cutting a hole in one go, use a Cool Down pass . sheetcam hot crack

Highly prone to forming brittle martensite phases upon rapid cooling.

Now, open your SheetCam job, adjust those settings, and cut with confidence. No cracks, just clean parts. Ensure your lead-in is long enough to keep

Starting a cut directly on the finished edge of your part forces the thermal shock of the initial pierce onto the final product. Without a proper lead-in, the start-point crater becomes embedded in the part geometry. 3. Material Composition

during lead-ins or sharp corners where the torch might dive and cause uneven heating. Optimized Lead-ins/Lead-outs: Instead of cutting a hole in one go, use a Cool Down pass

Highly prone to thermal cracking due to its high thermal expansion coefficient and wide solidification temperature range. Aluminum requires fast travel speeds and precise, short pierce delays.

Break up the cut path using SheetCam’s manual cutting options to let one area cool before finishing the adjacent cut.

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).
