笔者在近年来的工作实践中对渐开线齿轮、变位齿轮、修正摆线齿轮和非圆齿轮模具的加工,掌握了一些基本的工艺方法规律及辅助措施,有效地克服了一系列的困难而提高了加工精度。一、齿轮模具加工中的主要问题在线切割加工中,影响齿轮类精密模具加工尺寸精度和形状精度的主要因素有以下几个方面:1.坐标工作合执行误差和丝杠间隙对加工精度的影响对于开环控制方式的数控线切割机床,计算机控制的理论运动轨迹与实际运动轨迹之间存在着一定的误差,这个误差值分别由
In recent years, the author’s work on the involute gear, variable gear, cycloid gear and non-circular gear mold processing, mastered some of the basic rules of the craft methods and ancillary measures to effectively overcome a series of difficulties And improve the processing accuracy. First, the main problems in the gear mold machining In the online cutting process, the main factors that affect the dimensional accuracy and shape accuracy of the gear precision mold processing are the following aspects: 1. Coordinate work with the implementation of error and lead screw gap on the machining accuracy For the open-loop control of CNC WEDM machine, there is a certain error between the computer-controlled theoretical trajectory and the actual trajectory, the error value from
