A comparison of approximate methods for the analytical determination of profiles for disk cams with roller followers

This paper gives a comparison of two approximate analytical methods for determining disk cam profiles. The procedures are highly accurate for obtaining points on a cam with cylindrical followers. For both analytical procedures, the coordinates of the center of the follower are required at small increments of the cam angle. Both procedures can be easily programmed and depend only on the follower coordinates and not the follower type. A procedure for approximating the radius of curvature is also given.
