Abstract

Cam-modulated linkages are a combination of cams and traditional linkages. These mechanisms have the advantage of satisfying an infinite number of precision points for path generation and body guidance synthesis problems. It is possible to synthesize these mechanisms graphically; however, established graphical synthesis methods can be tedious and do not lend themselves to iterative mechanism design or optimization techniques. An analytical method for synthesizing cams for cam-modulated linkages using principles of conjugate geometry is presented. The method is valid for two-dimensional or three-dimensional mechanisms. The same method is used for followers undergoing complex motions. The method is applied to verify the synthesis of a high speed printing mechanism produced by Pitney-Bowes.
