Tutorial 6: Cams: Flat, Barrel, Globoidal, 'Slot'
Contents
Cams and Cam-Followers
Please do tutorials 1,2,3,5 before this tutorial.
In machines, in general terms, a cam gives a motion, that satisfies different design requirements, to a cam-follower. The cam-follower is in continuous contact with the cam.
Usually, the cam and cam-follower move. The cam usually has a simple motion and the cam-follower a more complex motion. However, it is also possible that the cam or the cam-follower is stationary.
Example of cams in a protected enclosure with forced oil feed, typical of a packaging machine.
As you design cams, you should notice a difference between MechDesigner and other software. In MechDesigner, you add the cam when your design is almost complete, and not when you start your design. New users are often confused: 'Why does the model not yet include a cam?'
