Cavitation Aided Machining for Finishing Glass Surface

Abstract

In this paper, the cavitation aided machining is proposed as a precision manufacturing method, based on the new concept using positively the cavitation that occurs in a suction flow for machining phenomenon. Then an efficiency of applying the cavitation aided machining as a precision surface finishing is proved by carrying out surface finishing on glass surface based on the machining phenomenon. Main conclusions obtained in this paper are as follows; (1) Fine finished glass surface with 60mm in length is generated by applying a fundamental machining phenomenon of cavitation aided machining along flowing direction fo machining fluid continuously. (2) WA abrasive grains generate finer machined surface than GC abrasives that is harder or AZ abrasives that have higher specific gravity.
