What is the displacement diagram?

Show answer

The displacement diagram is the key drawing for a cam. It plots the follower's displacement (vertical axis) against the cam's angle of rotation through one full revolution,

(horizontal axis). A rising line is the rise, a horizontal line is a dwell, and a falling line is the return. The diagram is effectively the design specification of the cam: from it the cam profile can be drawn.
