In the cam cycle, what is the term for when the cam follower does not change position?

In the cam cycle, the term that describes when the cam follower does not change position is "dwell." During the dwell phase, the cam follower remains stationary, allowing other processes or movements to occur without affecting the follower's position. This phase is essential in various applications where maintaining a fixed position is necessary for the timing of operations or synchronization with other machine components.

In contrast, acceleration refers to the phase where the cam follower is increasing its speed, while velocity refers to the phase of constant motion where the cam follower moves at a steady rate. The return phase is when the cam follower moves back to its original position after completing its designated motion, which is distinct from the dwelling period where no motion occurs.
