Laser scanning machining system for complex parts based on error correction
In order to reduce the part error in the process of complex parts processing,a laser scanning complex parts processing system based on error correction is designed.Based on laser scanning,the overall structure of the complex parts processing system is designed.Based on the overall architecture of the system,the laser scanning mod-ule is used to obtain the material information,and the grid correction method is used to correct the galvanometer error in the scanning unit;The laser scanning results are transmitted to the DSP control module,and the tool processing paths of different processing units in the processing module are determined through linear and circular interpolation op-erations.At the same time,the feedback signals such as the positions of different servo units are compared to realize the motion control of the manipulator module.The experimental results show that the laser scanning error of the system is controlled below 0.5 mm,which meets the fan application standard.The maximum processing time is 37 min,which effectively improves the application rate of parts.
