System design and low-speed characteristic analysis of electrochemical micro-machining set-up for micro-holes

Due to several advantages and wider range of applications, electrochemical micro-machining (EMM) is considered to be one of the most effective advance future micromachining techniques. In this work, a new electrochemical micro-machining set-up for machining metal micro-holes has been developed. Double level mechanical structure has been applied as the main structure style, which has the advantage of excellent structure rigidity, compact framework dimension as well as perfect maneuverability and maintainability. The characteristics of low-speed motion of the developed EMM set-up have been evaluated. In order to verify the reliability of the EMM set-up, some test works including static measurement, assembling interferences checking and kinematics simulation have been done. The simulation results demonstrate that the developed EMM set-up for manufacturing metal micro-holes has perfect characteristic of low-speed motion and can satisfy the technical requirements of electrochemical micro-machining process.
