Abstract
This thesis is concerned with the development and validation of interactive computer software that aids the design procedures for cam mechanism design, thereby facilitating the optimised design of the mechanism. Attention is focussed on the disc cam-translating roller follower mechanism with respect to which a series of analytical programs have been developed which addresses the design of the complete mechanism. This broad view of the mechanism design as opposed to concentrating on specific features thereof as has hitherto been the case, has been a major objective of the work reported in this thesis. Each analytical program shows the means adopted to satisfy the limiting conditions imposed by kinematic constraints and strength limitations encountered in cam design. The software enables the establishment of the design specification for the manufacture of the cam itself along with as much data on the other features of the mechanism (i.e. the spring, follower, and roller on follower) as project time could permit. A typical run of the software is shown, with the results presented in graphical as well as tabular format. This includes a graphical layout of the cam profile, the roller profile on the cam, and the roller and cutter paths around the cam profile. These results have been checked against independent work with good correlation.
