摘要

The importance of rapid tooling (RT) and additive manufacturing (AM) appears to be indispensable for boosting the process of manufacturing and expanding the horizon of production technology worldwide.This concept draws the attention of numerous scholars to arrive at a conclusive theory for the widespread utilization of RT.This study attempts to determine the viability and performance of an RT electrode in the field of electro discharge machining (EDM).The electrode prototype is made using an acrylonitrile butadiene styrene (ABS) plastic by fused deposition modeling (FDM),an AM technique,electroplated with copper of desired thickness,and used in die sinking EDM of D2 steel.The scanning electron microscope analysis of the electroplated samples confirms that it is possible to obtain the desired thickness of the metal by electroplating on any electrically conductive surfaces.In the present work,an experimental study is performed for examining the electroplated copper thickness of the plastic EDM electrode and its performances.It is found that the electroplated ABS plastic EDM RT electrode successfully performs the machining operation of D2 steel,and the results are comparable with a solid electrode.The study reveals that the RT electrode can be regarded as a viable tool for rough cutting or semi-finishing cut EDM functions.The experimental results are thoroughly discussed,examined,analyzed,and evaluated for the purpose of developing the appropriate form of the concept.
