Creating a Cylindrical Cam

Mechanism Design Extension in Pro/ENGINEER allows users to create planar cams. However, there is no built in functionality to allow for cylindrical cams. This technique shows users how to create a cylindrical cam with a follow. This cam will move the follower between two dwells.

The general approach is to have a cylindrical representation of the cam geometry and a planar representation of the cam geometry. When the mechanism is defined, the planar cam will move in translation and will have a cam connection to the follower. The geometry will be hidden from the assembly. The cylindrical cam will move in rotation to represent the motion but will not be driving the follower. The key is to drive the geometry of the cylindrical and planar cam with one reference. This will be done by using a family table of one cam part.
