工装生产中常遇到具有阿基米德螺旋面型面的样板或凸轮(如图1)。如何选择适当的加工方法,对于确保产品质量,提高劳动效率都有着重要意义。而决定精度和效率的关键工序是精加工工序。用切线包络法逐点磨削型面虽精度较高,但计算繁琐,且操作较难;用靠模装置加工,则需要有与工件曲 Tooling often encountered with Archimedes spiral surface profile of the model or the cam (Figure 1). How to choose the proper processing method is of great significance to ensure product quality and improve labor efficiency. The key process of determining accuracy and efficiency is the finishing process. With tangential envelope method of point-by-point grinding of the surface, although the accuracy is high, but the calculation is cumbersome, and the operation is more difficult; with the die device processing, you need to work with the song
