Implementing the engineering of reverse measure, exploiting new product from a high jumping-off point, assimilating and absorbing advanced technology, and knowing competitor's level and pulse is one of important approach to develop and improve home level of science and technology. Based on a corporation demanding to make the product, this text analyses the sample of cylindrical cam made in Japan, applied the technology of reverse design and manufacture. The part template was trial-manufactured and a batch part production completed successfully so customs demand was satisfied.This task's main work and pursuit is as follows:1. Based on the analysis working principle of cylindrical cam, the part's geometrical parameters was detected and reverse measured, including dimensions, shape, degree of position, roughness, configuration' s parameters and tolerance, the data of cam profile curve and so on. The part' s CAD graphics was protracted.2. Analysed the part' s technology, made the route of machining craftwork, including structure design, material, and heat treatment. The key technology of the cam surve profile' s NC machining was emphatically discussed, such as cutter' s design and machining, compensation of abrade wear, and made several tests. The whole process was well controlled.3. Summarized the list data of the reverse measure of cam' s profile curve, applied three times profile function, synthesized cam spatial curve, referring to the fact of machining by NC machine tool, series of working projects were brought forward for the whole process (data measure, curve fitting, NC machining, programming, analysis and establishment of machine technology).4.Accomplished the manufacturing of the pattern and a batch production. Practice showed "good effect of replacing Japan's product".5. Summed up a series of applied experience in practice. Accumulated valuable experience for the same type of NC machine. The method was applied on other parts that need 4-axis gang control.
