摘　　要：以数控机床磨削内斜齿轮为研究对象,研究在磨削过程中存在的加工误差及补偿问题。首先,通过齐次坐标变换原理,推导出工件到刀具之间存在误差的齐次坐标变换矩阵,得出加工过程中的几何误差模型;其次,利用内置信号同步采集方法,实现机床加工误差在线监测,并通过软件补偿原理对主要误差源进行补偿;最后,通过齿轮检测仪,对误差补偿前、后齿面进行检测,补偿后的齿面误差有所减小。该实验为提高机床加工精度的研究提供了数据理论支撑。Taking the grinding of internal helical gears by CNC machine tools as the research object,the machining error and compensation problems in the grinding process are studied.Firstly,through the principle of homogeneous coordinate transformation,the homogeneous coordinate transformation matrix with errors between the workpiece and the tool is derived,and the geometric error model in the machining process is obtained.Secondly,the on-line monitoring of machine tool machining error is realized by using the built-in signal synchronous acquisition method,and the main error sources are compensated by the software compensation principle.Finally,through the gear detector,the tooth surface before and after error compensation is detected,and the tooth surface error after compensation is reduced.This experiment provides data theoretical support for improving the machining accuracy of machine tools.
