초록Abstract:
This study suggested use of strip electrical discharge machining (strip EDM) for fabricating V-grooves. Traditional methods, such as cutting or grinding, make it difficult to deal with hard-to-cut metals and burr formation on machined portions is a concern. Although EDM does not cause these problems, this machining method has the disadvantage of electrode wear. The wear causes shape error and low productivity. To overcome these problems, an experiment using strip EDM was conducted to produce V-grooves. A thin conductive strip used as an electrode was bent around an electrode guide and its corner was shaped into a right-angle triangle. This shaped electrode was used to fabricate a V-groove. Since the suggested process was not concerned with electrode wear, new electrodes for finish cuts and tool path compensation were not required during the machining process. It was also possible to complete high precision machining because no burr or deformation was caused by the cutting force when compared with traditional machining methods. In the practical machining of this research, the patterns of V-grooves, prisms and pyramids were fabricated on a stainless steel workpiece.
