Experimental Study on Ultrasonic Vibration assisted Electrochemical Grinding of Small Holes

Electrochemical grinding, as a composite machining method, is currently widely used for drilling and milling of hard-to-machining materials. Based on the electrochemical grinding method, the ultrasonic vibration assists the hole enlargement process to improve the machining quality of small holes. In this paper, an experimental platform for ultrasonic assisted electrochemical grinding was set up, and a mathematical model for hole enlargement in ultrasonic assisted electrochemical grinding is established. The effects of ultrasonic vibration, electrical parameters and rotation speed of electrode on the machining quality of 304 stainless steel were studied.
