摘　　要：传统加工中的硬件水平决定了零部件加工精度,零件加工误差受环境、机床运动误差、刀具型面误差等多种因素影响,工件加工误差软补偿是通过修改加工代码的方式来修形。针对回转类零部件,在传统机床运动误差补偿、刀尖几何半径补偿的基础上,建立了基于样条插值的误差补偿算法,验证了利用实际型面数据进行样条插值的加工—检测—再补偿加工工艺路线。利用回转类零件进行加工误差补偿试验,试验结果表明,基于样条插值的加工误差补偿方法能进一步提高回转类零部件的加工精度。The hardware level in traditional machining determines the parts machining accuracy,and the parts machining error is affected by a variety of factors such as environmental,machine tool motion error,tool form error and so on.Workpiece machining error compensation is by modifying the processing code to repair the shape.For rotary parts,on the basis of traditional machine tool motion error compensation and tool tip geometric radius compensation,an error compensation algorithm based on spline interpolation is established,and the machining inspection and re-compensation machining process route utilizing actual profile data for spline interpolation is verified.Using rotary parts for processing error compensation test,the test results show that the processing error compensation method based on spline interpolation can improve the processing accuracy of rotary parts.
