Laser cutting is the world's most advanced cutting process, with the advantages of precision manufacturing, flexible cutting, special-shaped processing, one-time forming, fast speed and high efficiency. Laser cutting technology mainly uses a high-power density laser beam to irradiate the material to be cut, and obtains high power density at the focus of the beam, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material.

[0003] In the prior art, in order to ensure the high-quality operation of the laser cutting machine, the laser cutting machine needs to be tested before it leaves the factory to ensure that the performance and quality of the equipment meet the requirements and to ensure its normal use and long-term stable operation.
