Its advantage also lies in that it is safer and more convenient. For laser cutting of metal sheets, etc., as long as the required pattern is input into the supporting program of the dedicated laser machine, the laser machine can cut out samples according to the requirements.

[0003] The patent with the publication number CN216325916U discloses a laser cutting machine tool for assisting precise cutting, including a support base, a cutting machine tool body, and a cutting mechanism; the cutting machine tool body is fixedly installed on the top of the support base, a cutting mechanism is provided on the cutting machine tool body, a module is fixedly connected to the surface of the cutting machine tool body, a fixed block is fixedly connected to the surface of the support base, a chute is opened on the side of the fixed block away from the support base, two positioning plates are slidably connected to the inner wall of the chute, the two positioning plates are in a "U" shape, a support plate is fixedly connected to the bottom end of the fixed block, and the support plate is in an "L" shape; the workpiece of the module is clamped at the central part of the module through the positioning plates, and then the workpiece is precisely cut, which plays a role in assisting the precise cutting of the workpiece. However, the following problems still exist in the actual use of this patent:
