Working principle of CAM: A cam is mechanical rotating machine element which is used for converting one motion in to another. It is rotating machine element that gives reciprocating or oscillating motion to another element known as follower. Usually cams are rotated at uniform speed by shaft. The follower motion is predetermined according to the shape of cam . Cam rotates and doing so , imports reciprocating motion to follower, with which it is in contact. As the cam rotates, the follower is made to rise dwell and fall ,the lengths of times spent at each of these positions depending upon shape of the cam.


Types of CAM: 

Wedge/flat cam

Plane or disc cam

Cylindrical cam

Conical cam

 Helical cam

Radial

3-dimentional

Applications of CAM: 

Automatic machines.

IC engines.

Machine tools.

Printing control mechanisms.

Spinning and weaving machineries.
