摘要

The current article detailed the spark erosion characteristics and optimization of synthesized Udimet L-605 Alloy. It possesses excellent material characteristics of the alloy viz. hardness, tensile strength and density. Owing to their meritorious properties, they could not be processed using traditional machining techniques. The previous researches and proven results showed Electric Discharge Machining (EDM), is effective technology for Udimet L-605 alloy. The variable parameters viz. pulse on time, current output and spark voltage are utilized to assess the surface geometry, rate of tool wear and metal removal. Atomic force microscopy (AFM) is used to examine the machined surface. Furthermore, the study is extended with SEM characterization to interpret the change in the morphology of the cutting tool and work piece geometry The present work reveals the increase in current and working voltage and pulse on time proportionally improves the micro voids condition, crack propagation and melted molten material development. This is formed in both the electrode and the work piece.
