Not all metals are created equal. If you are using SheetCam to cut , your risk of hot cracking is much higher. : Reducing the feed rate (e
In the plasma world, a hot crack isn't an accident. It's a confession. It means the material was stressed beyond its limit while still molten. The CNC had moved too fast. The lead-in had been on the wrong side of the kerf. Or worse—SheetCam had sequenced the cuts so the last pierce was too close to the previous cut, trapping heat in a corner.
