Description

technical field

[0001] The invention belongs to the technical field of laser focus position detection and surface method vector detection of processed materials in laser three-dimensional cutting, and in particular relates to a measurement method with multi-point measurement function and a laser cutting head displacement sensor with multi-point measurement function, which can quickly Automatic vertical positioning of the laser head and detection of the distance between the laser head and the workpiece. Background technique

[0002] In the laser cutting process, in order to ensure the cutting quality, it is necessary to maximize the power density at the incision, which requires a certain gap between the nozzle of the cutting head and the surface to be processed, and the gap must be constant. The relative position between the laser beam focus point and the workpiece, that is, the defocus amount, is an important process parameter of laser cutting. During the cutting process, it...
