On the basis of analyzing the non-impact seal cam profile, CNC methods of cam profile are given.

Analytical method to determine the basic circle radius of a plate cam with a roller follower;

With the help of the property of instantaneous speed center and being aimed at the plate cam with a roller-swinging-follower,the author has established a set of analytic formulas for calculating both the borderline of the cam and the cutter central path.

The relationship between the manufacturing error of follower and cam profile and dynamic state of the follower in the plate cam mechanism was studied.

The parametric automatic solid modeling of disc cam with pushing bar in UG;

Design of Translating Flat-bottomed Follower Disc Cam Contour Based on UG

The moving control of laser cladding on the surface of disc cam is theoretically analysed.

This paper introduces the merits of the combination of software and AutoCAD software UG and disk cam NC machining and automated programming method.

According to the inlet requirements of the expander,disk cam mechanism is selected for its machining easy,and the follower(slide valve) movement role is sinusoidal acceleration.
