Products of electrolysis in the inter-electrode gap is one of the major factors influencing wire electrode micro-electrochemical machining precision. To enhance the efficiency of removing these products, a new method is proposed that allows the wire electrode to perform micro-amplitude reciprocating movement in the axial direction during the processing. The machining stability and accuracy can thus be improved and the machining efficiency is increased. A mathematical model is built to investigate the influence of the wire electrode travelling speed and micro-amplitude on removing the product and refreshing the electrolyte. Their effects of the electrode travelling speed and micro-amplitude on the machining accuracy and efficiency are investigated experimentally. A micro groove on an alloy is generated with the optimized parameters with a resulting surface roughness of about 0.45 μm and radius of chamfer is lesser than 8 μm。
