Adaptive Mechanisms for Reconfigurable Machines Based on Deformable Cam

This paper presents an innovative solution to make configurable an automatic machine based on a mechanical cam through the adoption of a cam with a flexible profile, controlled in a certain number of precision points by means of motors driving a recirculating ball screw. The dynamic effect of the followers on the flexible profile requires an iterative process to determine the kinematic performance of the system and the constructive aspects have been considered in detail, designing an original mechanism with positive guidance for the realization of the followers. The results obtained demonstrate the feasibility of the solution and the performances comply with the design requirements.
