Abstract
In industry there are many ring-type machine parts such as the inner and outer lace of bearing, the inner diameter (ID) and outer diameter (OD) of which need to be ground precisely. Usually in order to grind these parts two grinding processes are necessary. One is for OD grinding using a cylindrical grinder, and another is for ID grinding using an external grinder. Thus for reducing process cost and improving machining accuracy the simultaneous-ID/OD combination centerless grinding is expected to be suitable. However the ID and OD rounding mechanism in this process are very complicated because of its complicated geometrical arrangement. In order to investigate the ID/OD rounding action, a computer simulation method is developed in this work. This paper deals with the development of simulation method and reports some simulation results.
