Mechanism and Process Study of Ultrasonical Vibration Combined Synchronizing Pulse Electrochemical Micro-Machining
In order to solve the difficulty problem of machining conductive hard and tough materials, ultrasonic vibration combined micro-PECM (Pulse Electrochemical Machining) is proposed as a new technology. The basic principle, characteristic of micro-USM (ultrasonical machining), micro-ECM and PECM are discussed, the feasibility of ultrasonic vibration combined microPECM are studied. The ultrasonical combined synchronous electrochemical micro-machining system are built and improved, which machining parameters can be adjusted in a wide ranges, and the synchronous target of the ultrasonical vibration and the voltage of micro-PECM can be realized. The micro-machining electrodes are manufactured in different sections and sizes by combined electrical discharge machining, such as WEDM (Wire Electric Discharge Machining), micro-EDM by copy adding translate, etc. The electrodes are suitable for the micro machining. The mechanism tests of ultrasonic vibration combined micro-PECM are carried, which kentaniums YG8 is machined and the results are analyzed and discussed. Contrast with the single micro-USM, the ultrasonic vibration combined micro-PECM has high productivity, good machining accuracy and surface quality, furthermore, its cathode wastage is low. The ultrasonic vibration combined synchronous micro-PECM has better machining precision and surface quality.
