五轴工具磨床通用后置处理研究

General Post Processing of Five-axis Tool Grinding Machine

数控机床后置处理能将刀位轨迹转换为机床数控加工程序,其先进程度对零件加工质量和效率有重要影响。目前五轴工具磨床后置处理大都专机专用或另外购买专用后置处理模块。通过对五轴工具磨床的结构类型分析,建立通用五轴工具磨床运动模型,并采用机床运动创成函数将砂轮的位姿转换为机床各轴的运动量,从而得到五轴工具磨床通用后置处理方法,提高了五轴工具磨床后置处理算法的通用性。

The post-processing of machine tools is to convert the tool path to the CNC machining program.Its advanced nature has an important impact on the quality and efficiency of the part processing.At present,the five-axis tool grinder is processed by a special plane or a special post-processing module purchased by the user.Analysis of the structure type of the five-axis tool grinder,a general five-axis tool grinder motion model is established and by establishing the machine tool creation function,the posture of the grinding wheel is converted into the movement amount of each axis of the machine tool,thus obtaining a kind of universal post processing algorithm for five-axis tool grinding machines.The algorithm improves the versatility of the five-axis tool grinder post-processing algorithm and has positive significance for the five-axis tool grinder processing application.
