Abstract

In this work, the machinability aspects of aluminium (LM6) alloy in wire electrical discharge machining were discussed. Owing to the poor machinability of LM6 alloy, WEDM is selected as the potential candidate to process it with utmost surface quality. The main intent of the work is to investigate the impact of the WEDM process parameters for the performance measures material removal rate and surface roughness. Further, resolidification layer of the WEDMed surface has been studied. Taguchi technique has been adopted to conduct the experiments. SEM micrographs revealed the surface integrity of the machined region. The pulse-on time and peak current were identified as the major parameter on deciding the material removal rate and surface roughness. LM6 has copious applications in marine, aircraft and automobile industries owing to its low cost, lightweight and excellent corrosion resistance.
