Essentially, your toolpath is "cracking" the integrity of the part because the physics of the cut weren't accounted for in the CAM software.

Do not use a straight lead-in. In SheetCam, navigate to the Cut path tab.

Different metals react uniquely to the thermal stress induced by SheetCam operations. Hot Crack Risk SheetCam Solution Extremely High

Are the cracks happening on or inside holes ? sheetcam hot crack

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.

High-carbon steels, certain grades of stainless steel, and specific aluminum alloys are naturally prone to hot short cracking. Their chemical makeup makes them sensitive to rapid thermal cycling. 4. Incorrect Cut Direction and Heat Buildup

Hot cracking is a metallurgical phenomenon that happens at elevated temperatures as the metal transitions from a liquid to a solid state. As the CNC torch passes, it creates a localized melt pool. When this pool cools, the metal shrinks. Essentially, your toolpath is "cracking" the integrity of

An overcut tells the torch to continue moving past the starting point of the cut loop before shutting off.

While SheetCam is primarily used for industrial and technical purposes, it can also be used in creative and recreational projects, such as:

While SheetCam itself generates the path, the resulting thermal stress from the cut parameters it manages can lead to cracks, particularly in sensitive materials. This article explores what hot cracking is in the context of SheetCam, why it happens, and how to optimize your SheetCam settings to prevent it. What is Hot Cracking in CNC Plasma? Different metals react uniquely to the thermal stress

Impurities in plasma air (moisture/oil) alter arc chemistry and increase heat. Install high-efficiency air dryers and filters.

Cracks can expand during subsequent welding, bending, or powder coating processes. How SheetCam Settings Influence Hot Cracking
