These cams are principally used to convert rotational motion to linear motion parallel to the rotational axis of the cylinder.

Displacement diagrams are traditionally presented as graphs with non-negative values.

A simple displacement diagram illustrates the follower motion at a constant velocity rise followed by a similar return with a dwell in between as depicted in figure 2.

Cylindrical cams may also be used to reference an output to two inputs, where one input is rotation of the cylinder, and the second is position of the follower axially along the cam. These were once common for special functions in control systems, such as fire control mechanisms for guns on naval vessels A face cam produces motion by using a follower riding on the face of a disk.

The most common type has the follower ride in a slot so that the captive follower produces radial motion with positive positioning without the need for a spring or other mechanism to keep the follower in contact with the control surface.

Face cams may provide repetitive motion with a groove that forms a closed curve, or may provide function generation with a stopped groove.

Cams used for function generation may have grooves that require several revolutions to cover the complete function, and in this case, the function generally needs to be invertible so that the groove does not self intersect, and the function output value must differ enough at corresponding rotations that there is sufficient material separating the adjacent groove segments.Each tool movement or operation was controlled directly by one or more cams.Instructions for producing programming cams and cam generation data for the most common makes of machine were included in engineering references well into the modern CNC era.We […]Do you want your toes to curl when you have an orgasm?

Certain cams can be characterized by their displacement diagrams, which reflect the changing position a roller follower (a shaft with a rotating wheel at the end) would make as the cam rotates about an axis.
