Abstract

In this study, 301 stainless steel microholes are drilled using an electrode with an ultrasonic vibration-integrated array. It is described how various processing properties are affected by machining factors including electrode feed rate, operating voltage, and ultrasonic vibration amplitude. The outcomes of the experiment demonstrate that the periodic pressure difference for the electrolyte is produced by the vibrating electrode array supported by ultrasonics. Both a cavitation effect and a pumping effect are created by the periodic pressure difference. The two effects can efficiently remove the reaction heat, reactive products, ...
