What is the easiest way to create a simple cam in Inventor? Your first response might be: “Just create a sketch outline of the cam using the Spline function and then extrude.” It makes sense right? The problem with the Spline method however, is it has a tendency to not create one continuous smooth edge and create a break in the face of the edge. This can lead to the follower not behaving correctly.
A better solution is the Disc Cam Generator which creates a fully functioning cam for you in the assembly model along with a separate part file for the cam.
