8.1 Introduction of Electronic Cams
A traditional mechanical cam is composed of a cam, a follower, and a support.
1. A mechanical cam is a rotating sliding piece with irregular shape. In general, it is an input object
which rotates at a uniform speed. It makes a follower move regularly by coming into contact with
the follower.
2. A follower is a part driven by a mechanical cam. In general, it is an output object which
generates motion which is not uniform, sequential, and regular motion.
3. A support is a piece that which is used to support a mechanical cam and a follower.
Compared with a traditional cam, an electronic cam has the following advantages.
1. Friendlier user interface
2. Different products require different cam curves. Users can modify the electronic cam data in an
electronic cam in software. They do not need to modify a mechanism.
3. High acceleration
4. Smoother operation
