Sheetcam Hot Crack |best|

Optimizing SheetCam settings is crucial for reducing heat input and preventing cracks. 1. Optimize Feed Rates (Speed)

: Improper torch height can cause excessive heat buildup. SheetCam includes "Cut Rules" to disable THC during tight corners or lead-ins, preventing "torch dives" that could damage the material or cause thermal stress leading to cracks.

While SheetCam itself is a software tool and does not physically heat the metal, the way you configure your toolpaths, lead-ins, and pierce delays within the software directly dictates how heat builds up in the material. What is a Hot Crack? sheetcam hot crack

If your torch sits stationary for too long while piercing the metal, it dumps excessive heat into a concentrated zone. This intense heat input creates an oversized molten puddle that is highly susceptible to cracking as it cools. 2. Poor Lead-In and Lead-Out Configurations

Not all metals are created equal. If you are using SheetCam to cut , your risk of hot cracking is much higher. Optimizing SheetCam settings is crucial for reducing heat

To solve the problem, you must respect the three states of metal: Expansion, Fusion, Contraction.

Hot cracks happen when the thermal contraction strains exceed the mechanical strength of the solidifying metal. Three main factors contribute to this failure: SheetCam includes "Cut Rules" to disable THC during

Use SheetCam to program a "pre-heat" or use specific path rules that avoid sharp 90-degree corners, which act as stress concentrators.

To prevent the "blow-out" or cracking that occurs at the start of a cut, SheetCam allows for customized lead-ins (arc, tangent, or perpendicular). By piercing the material in a waste area and moving into the path, the initial thermal shock—the most likely moment for a hot crack to initiate—is kept away from the finished edge.
