【Abstract】 Eletrochemical pattern transfer machining,as the innovation of electrochemical machining technology,is the efficient and parallel forming method used for fabricating metal surface texture. It do not manufacture and remove photoresist patterned mental workpiece and prepare micro-electrodes before. In this work,the modified Eletrochemical pattern transfer machining of metal surface channels was proposed. The influence of voltage,inter-electrode gap,frequency and duty cycle of pulse, electrolyte inlet pressure and machining time on the processing localization were investigated orthogonal experimentally. It created Serpentine channels with good localization of 21μm in depth and 237μm in width on the steel and concluded that voltage is the main factor for localization of channels. On the condition of optimal level of machining parameters: voltage of 12V,inter-electrode gap is 100μm,the frequency and duty cycle of pulse are 0.4 kHz and 40% respectively,electrolyte inlet pressure is 0.09 MPa and machining time of 100s,the highest localization of channel would be achieved.更多还原
