COMPUTERIZED SOLUTION OF
SPATIAL CAM SURFACES WITHOUT
SURFACE EXPRESSIONS*

Abstract: A computerized method is presented to calculate the spatial cam surfaces without their analytic expressions. Given the definitions of the follower surface and the assembly configuration as well as the motions, a computerized model and algorithm are developed to compute the cam surfaces through transformation of the enveloping condition. This new idea makes it possible to construct a truly versatile CAD/CAM program for whatever type cam mechanisms. This new method is illustrated with an example.

Key words: Computerized solution Cam surface
