Macro Program Design of Variational Trapezoid Curve Disk Cam

Abstract

Based on the design parameters of disc CAM with the oscillating roller follower and modified trapezoid curve follower motion, by introducing macro program cyclic variable, the mathematical calculation model of macro program about cutter path of disc CAM with the holonomic constraint oscillating roller follower is established. The macro program is designed to can be adjusted quickly, according to the design parameters and the process parameters. The numerical control program completely parametric design is realized. So it provides programming methods and strategies for numerical control machining macro program design of the oscillating roller follower disc CAM with a complicated movement law.
