Abstract
In this paper we introduce the kinematic analysis of two circular-are cams with profile design and experimental validation. In particular, an algorith m is proposed in terms of geometrical parameters and the cam profile, mainl y for design purposes. Numerical examples are reported to prove the soundne ss of the proposed algorithm. Displacement, velocity and acceleration diagr ams are obtained for the synthesized cam profile by means of equivalent sli der-crank mechanisms, in order to derive a simple procedure for testing cam profiles with a low-cost test-bed. An experimental test-bed has been set u p at the Laboratory of Robotics and Mechatronics in Cassino in order to val idate the kinematic characteristics of the two circular-are profiles so tha t the experimental results can be used also to test the profile quality.
