107 Development of a CAI system for simulating 3-dimensioanl mechanism construction : Implementation of cam mechanisms

Abstract

We have developed a computer assisted instruction (CAI) system that supports study of gear mechanisms by simulating 3-dimensional mechanism construction. In this study, we expanded the capability of the system by adding the blocks correspond to cam mechanisms. A plate cam, a heart cam, and a cylindrical cam were chosen for the implementation. The parameters for making cam mechanism blocks are restricted to the fundamental ones for learning. Since those parameters depend on the kind of cam, the kind is firstly selected for setting the mechanism on the system field. The function to display the cam diagram was also added to the system for convenience of understanding.
