The Invention of Cam-Linkage Grinding Device with Double-Circle Grinding Traces

Abstract

Abstract The double-circle grinding traces has 0% velocity deviation percentage (Vdp =0%), which is the optimum polishing trace. This paper focuses on the invention of cam-linkage grinding devices with double-circle grinding traces. First, based on the modified Yan’s creative design methodology, 1st cam-linkage grinding device is synthesized. Then, according to Osborn’s Checklist Method, 2nd cam-linkage grinding device is synthesized. These two cam-linkage grinding devices can be designed to have optimum polishing traces and 0% velocity deviation percentage (Vdp =0%). This paper provides a new creative design methodology for creating some or all possible design concepts that have the different topological characteristics as existing designs, e.g. with the different degrees of freedom. It can be said to create some or all possible design concepts from nothing (no existing design). The results of this paper can be used as the teaching material of innovative design course.
