In the laser processing process, the energy of the spot and the distribution of energy in space have a great influence on the laser processing capability and speed. When processing thick plates, the laser beam is stationary relative to the mechanical body of the cutting head, and does not generate a motion trajectory relative to the mechanical body of the laser head. Therefore, the highest energy point of the laser cannot be well transmitted to the area to be processed on the plate, which may easily cause the energy of the laser beam to Low utilization rate, low cutting efficiency, sticking of workpieces or degradation of cutting surface quality

The present invention relates to the technical field of laser cutting, and specifically provides a laser cutting spot control system and method, including: a host computer and a laser cutting spot control device; spot track parameters, and transmit the input spot track parameters to the main processor; the main processor fits the input spot track parameters through the graphics processing module to form the spot track graphic data, that is, the cutting coordinate set; the storage module is used to store the operator The input spot trajectory parameters and the cutting coordinate set. Compared with the non-variable laser head with spot track, the present invention can realize the cutting of thicker plates compared with the laser cutting with non-variable spot track. When selecting the cutting spot track parameters, When the shape of the spot swing is selected, the size and pattern of the spot can meet the cutting needs and ensure the cutting quality.
Description
Technical field [0001] The present invention relates to the field of laser cutting techniques, and more particularly to a laser cutting spot control system and method. Background technique [0002] Laser cutting utilizes the focusing high-power density laser beam to irradiate the metal sheet, allowing the metal sheet to rapidly melt, gasify, ablate or reach the combustion point while blowing out the melt substance by means of a high-speed air flow coaxial with the beam, thereby achieving a metal sheet Cut. Compared to plasma cutting, flame cutting, wire cutting, laser cut has the advantages of small thermal affected zone, fast cutting speed, good cutting quality, and rapid use in metal plate cutting processing. [0003] During the laser processing, the distribution of the energy and energy of the spot on the distribution of the laser is large and the speed is affected. In the conventional laser processing technology, since the laser heat is gradually attenuated, especially when t...
