Investigation of Machining Characteristics of Ultrasonic Vibration Assisted ECM

Abstract:

In ECM process, insulating by-products exists in the inter-electrode area. These by-products disturb the current flow between the tool and workpiece electrodes, and thus affect the machining accuracy. As one of the ways to remove the by-products, a method was proposed to apply ultrasonic vibration to the tool electrode. However, the influence of the electrolyte concentration and the effect of ultrasonic vibration on the machining characteristics of the WC alloy have not been investigated yet. Therefore in this study, these influences were experimentally investigated. It was found that the machining accuracy is increased by using the low concentration electrolyte. Also, machining of the tungsten carbide (WC) alloy when applying the ultrasonic vibration to the tool electrode becomes possible.
