Abstract

Composite materials and super alloys find wide range of applications in aerospace, ship building and automotive industries. Both composite and super alloys show improved mechanical properties at elevated temperature and pressure. The machining of composites and super alloys is a challenging field because of their poor machining performance. The machining of both composites and super alloys is difficult by using conventional machining. The issues regarding machinability of composites and super alloys have been vanquished by using nontraditional methods, and mostly used non-conventional machining technique is wire electric discharge machining (WEDM). This paper reviews the recent advances in machining of composites and super alloys by using Wire-EDM. This study finds that there are various important WEDM parameters, viz pulse on time (POT), pulse off time (PFT), servo voltage, wire diameter, peak current, spark gap voltage and dielectric conditions which need to be optimized to obtain maximum value of material removal rate (MRR) and minimum value of surface roughness (Ra), kerf width and electrode wear rate during machining of composites and super alloys.
