成形曲面的加工是机械制造中的一个难题。保证凸轮加工精度,自然成为一系列机械产品(如自动锻压机、印刷机、纺织机、自动包装机及其它自动机等)上的基础件攻关项目。不少产品的精度、生产率和寿命与先进水平的差距,都直接和凸轮精度有关,这一点在用高速凸轮的机械上尤为突出。目前凸轮的加工都用靠模仿形铣或磨的方法,除了汽车凸 Forming the surface is a mechanical manufacturing problem. To ensure the accuracy of cam processing, of course, become a series of mechanical products (such as automatic forging presses, printing presses, textile machines, automatic packaging machines and other automatic machines, etc.) on the basis of the key pieces of research projects. Many products, precision, productivity and the gap between life and advanced level, are directly related to the accuracy of the cam, which is particularly prominent in the machinery with high-speed cam. At present the cam processing are used by copy milling or milling mode, in addition to car convex
