According to conception of instantaneous velocity, this paper introduced the principle of a new graphic method for designing cam profile curve and calculating cutter center track of disk cam with oscillating flat-face follower,and described a CAD animation progress about how to realize it by AutoCAD software.

This paper by analytic method gives description of some parameter selection of the earn mechanism with flat-face oscillation follower, describes its bar length, radius of earn base circle, and the design way of earn profile and CAD program to promote the disign and application of the earn mechanism with flat-face follower.

The article that is based on theoretical knowledge of the discrete math and the computer technique provide numeric stimulate pattern of the flat-faced follower eccentric circle institution, which is applied to resolve the wearing problem of flat-faced follower eccentric circle institution.

For plate cam mechanism with flat-faced follower, this paper derived the formula and the curvature expressions of cam convex profile curve, which can be applied to both translating follower and to oscillating follower.

Based on the geometrical condition in which the cam profile is not self intersecting, the design equations of the minimum radius of disk cam with flat-faced follower are presented and some examples are given.

Efficiency calculation model of disc cam mechanism with translating flat-bottomed follower;

It is best among the earn mechanisms that the dynamic property of the earn mechanism with flat-face follower.
