Description 

Cam, a machine element with arbitrary shape, is a device for transmitting arbitrary motions to the other side by direct contact. As only one side needs arbitrary shape to transmit an arbitrary motion, the other side usually adopts simple shape of roller or 평면 (flat panel, floor, flat plate?). 

Remarks 

Strong points 

- Easy conversion rotational motion into rectilinear motion 
- Good Motion characteristic and endurable in high velocity 
- Stable operation as a Positive motion device. The equipment’s operating time set by mechanically rotating angle of Cam is constant, therefore, how many seconds takes to complete the operation and the range it moves are supposed to be all set, as well as the follower’s position at an arbitrary timing of stroke during the operation. 
- Rare malfunction and easy repair. 
- arbitrary stop available with Cam devices while linked equipment is not. 

*Weak Points 

- Difficult to Change or adjust stroke and timing fixed 
- Protective Device required. 
- Difficult to Design and Process
