Influence of Performance Indicators on Maraging Steels during Spark Erosion Machining
Main Article Content
Abstract
Superior levels of strength and hardness of Maraging Steel (MDN 250) leads to difficulty in machining. For machining to be effective, performance indicators must be optimized. This study discusses the Taguchi approach, which is used to optimize electrical discharge machining (EDM) performance indicators and estimate the effect of process parameters on MDN 250 steel. Material removal rate (MRR), Surface roughness (SR) and Squareness were among the process performance indicators that were evaluated. The most important variables influencing EDM performance are discharge current and pulse duration from the previous research studies. The results of the present investigation show that pulse duration and current are important factors in EDM operations to get précised machined components.
