摘　　要：针对降低复杂零件加工过程中的零件误差问题,设计基于误差修正的激光扫描复杂零件加工系统。以激光扫描为基础设计复杂零件加工系统的整体架构。基于系统整体架构利用激光扫描模块获取材料信息,并采用网格修正法修正扫描单元中的振镜误差;将激光扫描结果传输至DSP控制模块内,通过直线、圆弧插补运算确定加工模块内不同加工单元的刀具加工路径,同时利用不同伺服单元的位置等反馈信号对比,实现机械手模块运动控制。实验结果显示该系统激光扫描误差控制在0.5 mm以下,符合风机应用标准,加工时间最高为37 min,有效提升了零件可应用率。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 module 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 operations.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.
