Sheetcam Hot Crack [exclusive] -

The order in which SheetCam cuts your parts matters immensely. If the torch cuts a small hole inside a larger perimeter immediately before cutting the outer edge, the heat from the hole is still radiating when the outer cut begins. This creates a "hot zone" where the material properties change, leading to poor cut quality on the perimeter.

If you're experiencing hot crack issues with SheetCam, I recommend consulting the software's documentation, online forums, or support resources for more specific guidance on troubleshooting and resolving the problem. sheetcam hot crack

or delayed cracking, occurs when the thermal stress from plasma or flame cutting causes the material's edge to fracture. This is most common in high-carbon steels or wear plates and is driven by: CUMIC Steel Residual Stresses: The order in which SheetCam cuts your parts

SheetCam serves as the bridge between CAD design and machine G-code. Its configuration directly impacts the "Heat Affected Zone" (HAZ), where hot cracking is most prevalent. 2.1 Lead-ins and Lead-outs If you're experiencing hot crack issues with SheetCam,

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

When a torch finishes a closed loop (like a circle), it often leaves a small "divot" or a localized hot spot where the start and end meet. This is a prime location for a crack to propagate.
