“…A number of conventional curves have been suggested to express the cycloidal, the modified sin curve, the modified trapezoidal curve, and the B-splines (Tsay and Lin, 1996;Wu et al, 2009;Sateesh et al, 2009;Xiao and Zu, 2009;Reeve, 1995;Nga et al, 2021;Qiu et al, 2005). In these studies, B-spline has been used to define the displacement function, which is satisfied by discrete constraints on follower displacements, velocities, and accelerations.…”

This study proposes a multi-criteria design optimization of cam mechanisms. This approach is based on the multistage interconnection of different tools: MATLAB, ADAMS, and mode frontier. It consists of three main issues: (i) The polynomial representation of splines given by checkpoints defining the specific motion of the follower; (ii) The connection of these splines by different degrees of fitting in order to combine them in the entire cam profile and (iii) The optimization including the adjustable checkpoints according to the objectives and the constraints formulated for a different area of the cam profile. An illustrative example based on the optimization of a production machine cam profile is discussed. The suggested methods of multi-criteria design optimization are validated by experimental tests. The given results show the effectiveness of the proposed approach and the possibility of their application in the real world of manufacturing.
