✦ Synopsis

A simple approach to the profile determination and machining of cylindrical cams with translating conical followers is presented. On the basis of the theory of envelopes for a 1-parameter family of surfaces, a cam profile with a translating conical follower can be easily designed once the follower-motion program has been given. In the investigation of geometric characteristics, it enables the contact line and the pressure angle to be analysed using the obtained analytical profile expressions. In the process of machining, the required cutter path is provided for a tapered endmill cutter, whose size may be identical to or smaller than that of the conical follower. A numerical example is given to illustrate the application of the procedure.
