Kinematical system of breadth cam profile design

The design solutions for breadth cam mechanism were presented. The main topics of the shape design for breadth cam was to calculate the coordinate at each contact point to determine the cam profile. The proposed method according to velocity and geometric relationships of instant velocity centers can easily determine each contact point at any instant moment. The cam profile was defined by contouring of the contact points. And also a program was developed by using Microsoft Visual C++ program, which can quickly and easily draw a 2D cam profile through the displacement diagram. Finally, the program was used to confirm the accuracy on the breadth cam profile design by computer animation graphically.
