| Research Abstract |
The purpose of this study is to generate a free form surface of tungsten carbide alloy by electrochemical machining. To achieve this goal, the following five trials were conducted, (1) analysis of factors affecting the machining accuracy with an equivalent circuit for the electrochemical machining process ; (2) establishment of a control system for contactless detection of the distance between electrodes ; (3) evacuation of by-products from the inter-electrode area by means of tool electrode vibration ; (4) production of micro pins of tungsten carbide alloy under by adding workpiece rotation and ultrasonic cleaning ; and (5) shape generation by superimposing simple grooves.
