ABSTRACT :

Wire electrical discharge machining (WEDM) one of the most used non-traditional machining process for machining difficult to machine materials and can produce intricate shapes with high degree of accuracy and surface finish. WEDM has been emerging from making tools and dies to the best alternative of producing micro scale parts. There are certain limitations which need special attention like wire lag phenomenon and geometrical inaccuracy caused due to wire lag phenomenon. Many researchers have made an attempt to minimize the geometrical inaccuracy. This literature review mainly focused on machining of corner radii, taper cutting and geometrical inaccuracy caused by the WEDM. This paper reports on the various research trends to visualize the effect of various process parameters like pulse duration, gap voltage and wire materials on the process responses namely material removal rate (MRR), surface roughness (Ra), Kerf width and surface integrity factor.

Keywords: WEDM, voltage, pulse duration, wire material, surface roughness, MRR, kerf width
