The design of motion diagrams is essential for analyzing follower dynamics.
Pressure angles and undercutting are crucial factors in cam design.
Cam
A rotating machine element that imparts reciprocating or oscillating motion to a follower.
Follower
An element that follows the motion of the cam, which can be of various types such as knife-edge, roller, flat-faced, and spherical.
Pressure Angle
The angle between the direction of follower motion and the normal to the pitch curve, influencing force transmission.
Undercutting
Material removal that causes loss of contact between the cam and follower.
Motion Diagrams
Graphical representations of follower motion enabling analysis of displacement, velocity, acceleration, and jerk.
