| Abstract |
In this paper, we have overviewed the achieved results also with an attempt to an extension to a general case that we think can be useful for studying and validating any cam profile.
Cam profiles with circular arcs can be useful for low-cost transmissions and for
applications in micro-machines. They have been usually designed by means of graphical techniques. Recently, at LARM in Cassino a research line addresses the attention to the problems of modern design and characterization of cams with circular-arc profiles by looking at computeroriented formulations and by investigating experimentally the operation characteristics. In this paper, we have overviewed the achieved results also with an attempt to an extension to a general case that we think can be useful for studying and validating any cam profile. The approach is of algebraic nature since it is based on the geometry of the mechanical design of circular-arc profiles by using their peculiarity. The experimental analysis has been conceived by preserving the lowcost
easy-operation performances of the circular-arc profiles by using a suitable test-bed that has been designed at LARM in Cassino. The results of experimental tests are useful to validate both the numerical design procedure and designed cam profiles. Examples are reported to illustrate the practical engineering feasibility of the proposed analysis procedures for circular-arc cam profiles.
