Quick Return Crank Mechanism 
When a reciprocate motion is needed, a quick return crank mechanism will be used to convert rotary motion. The stick will rotate left to right when the disc rotate.
Shaping Machine
It is used when a large amount of metal has to be removed. The machine will move forwards and backwards pushing the cutting tool as the disc rotates.
Crank and Slider Mechanism
When the cam rotates, the rod connected to it will push the slider into the tube and out of the tube as the cam is an eccentric cam.
Rachet Mechanism
A pawl will follow the wheel when it is turn. The rachet can only rotate anticlockwise. It will get stuck when it rotate clockwise.

Swash Plate Cam
Today I am going to introduced another type of cam, the swash plate cam. A shaft rotates around the a disc that is set at an angle so the disc will rotate when the follower moves up and down.Each follower has a roller to ensure a smooth movement.
