In this research work, an attempt was made to machine the titanium (Ti6Al4V) alloy utilizing electric discharge machining technique. e distinct process parameters and its impact on the machining performance were identified using the cause-and- effect diagram (CED). e key process parameters identified by CED diagram were current, pulse on time (Ton), aluminium oxide (Al 2 O 3 ) powder concentration, and gap distance; experiments were conducted by varying the process parameters, experimental runs were designed using the Taguchi mixed orthogonal array. e experimental results revealed that improvement in material removal rate (MRR) was due to the bridging effect; reduction in tool wear rate (TWR) owing to the expansion of spark gap and enhancement in the surface roughness (Ra) was due to the complete flushing of machined debris. e interaction impact was analysed using the contour plot and with the aid of mathematical modelling experimental fits that were identified and the results were validated utilizing the sensitivity analysis. e obtained results were optimized using the technique for order of preference by similarity to ideal solution (TOPSIS) optimization technique. 1. Introduction e life time of the product depends on the quality of the component used to assemble it. e manufacture of main landing gears from composites using conventional machining processes has distinguishing critical to excellent attributes [1]. e attributes include excessive tool wear due to the presence of abrasive particles in the composites, formation of build-up edges, and exhibiting poor surface as the removal of particles leaves the pits on the surface [2–4]. To resolve this issue, the composites were manufactured using the unconventional machining (UCM) technique, of which electric discharge machining (EDM) was preferred for producing components with utmost quality [5]. e EDM input variable which controls the outcome of the process includes current, spark gap, powder concentration, cycle time, and tool materials [6–8]. Tuning the parameters to the ideal level results in the manufacturing of high-quality items; failing to do so results in faulty products [9]. e route cause for the distinct defects was identified using the CED diagram. e CED, also known Hindawi Advances in Materials Science and Engineering Volume 2022, Article ID 6164599, 10 pages https://doi.org/10.1155/2022/6164599
