• Rise (move up)

  žFall (move down) or

  žDwell (remain stationary)

• Rise (move up)

  žFall (move down) or

  žPush/Pull (in or out movement)

In relation to CAMS what is a cycle?

• The shifting of the cam from one point to another random point

• The clockwise movement of the cam

• A 180 degree movement of the CAM

• One rotation/revolution of the cam.

In relation to CAMs what is the DWELL?

• When there is no movement of any part of the CAM

• When the cam rotates but the follower does not rise or fall.

• When the follower rotates but the cam does not rise or fall.

• The part of the CAM the sits on the edge of the follower
