Experimental Research on WEDM Machining for Metal Components with Micro/Meso-scale

In order to meet the machining demand of the metal components with micro/meso-scale, a kind of micro-fabrication method is explored by Wire-cut Electric Discharge Machining (WEDM). To find solutions for the problems of machining, a series of WEDM experiments for the micro/meso-scale structure of a thin nickel plate are carried out based on the analysis of technology regularity of WEDM. Experimental results indicate that the reasonable constraint on the discharge energy is the key to finish the machining of the metal components with micro/meso-scale. The stable machining can be achieved by adjusting discharge parameters to lower levels. The micro/meso-scale machining defects of cantilever distortion and sharp corners bending can be solved by segmented and multiple cutting accordingly. At last, some examples of complex structures machined are shown.
