DISPLACEMENT DIAGRAM FOR A CAM

The displacement diagram is one in which the abscissa (i.e., X-axis) represents the angular displacement of cam and the ordinate (ie., Y-axis) represents the corresponding displacement of the follower from its initial position.

A typical displacement diagram for a cam is depicted in Fig.3.12.

The displacement diagram consists of three distinct parts: rise, return, and dwell.

Dwell is the period during which the follower remains at rest. Dwell may be between rise and return, and after return also.


It may be noted that the points of inflexion during rise and return portions correspond to the pitch points.
