What is the cutting principle of the cutting machine used by fashion design students?

The garment cutting machine acts on the laser power supply through the instruction issued by the control card, and the booster laser tube emits a beam, which is focused on the workbench for three times to form a laser spot. The laser spot releases energy on the surface of the workpiece, melting and evaporating the workpiece. The current signal converted by the driver drives the motor to rotate, drives the belt, and then drives the light beam to move the laser head, thus completing the cutting and cutting purposes.
