9. CAM DESIGN
À pCams are basically shaped surfaces that are typically not round. The cam is rotated or translated, and a follower (possibly a small wheel) is displaced as it moves over the surface.
Cams can generate complex motion profiles in a compact area.
Engine values are a well known application of cams. They can open and close the cylinders with a large force, but will also dwell in open or closed positions.
