This paper studies the machinability of BK7 optical glass by using conventional ultrasonic machining (USM) and rotary ultrasonic machining (RUM). For USM, the finer grit size gives low MRR, good surface finish, small chipping size and low opaqueness. In RUM, higher spindle speed gives good MRR, exce...
