A CAM is requiered in a automatic transfer mechanism. CAM follower should raise outward 1.0 inch at a constant speed in 3.0 seconds, making a stop of 5 seconds, to descend at a constant speed in 2 seconds and then repeat the sequence.
Determine:
a) the required speed of the CAM;
(b) Develop graphically the diagram of displacement of the follower and
(c) The profile of the cam to a rotation of this in the same sense that the movement of the hands of the clock.

Solution

Ascend Period = 3 seconds

Dwell Period = 5 seconds

Descend Period = 2 seconds

Total Time = 3 + 5 + 2 = 11 seonds

Angualar Speed = Angual Displacement / Time = 2 pi / 11 = 0.571 rad/sec
