Surface integrity assessment techniques in EDM process for enhancement of product’s performance : a review

ABSTRACT

In today’s scenario, micro-machining process such as μ-EDM finds numerous applications. In μ-EDM process, the specification of the tool is less than 1000 μm. It’s a thermo-electrical phenomenon in which object gets eroded by consecutive sparks in between tool and the workpiece. Various process parameters are used in this process. The variation in the process parameters affects the quality of the machined surface. Surface quality analysis is an essential task for achieving appreciable performance of the product during its intended span. For analysing it, various techniques are used. In this work as an objective, the different techniques employed for analysing the integrity of machined surface for enhancement of product’s performance are detailed. In continuation, it is also concluded that analysis of machined surface’s integrity provides a supporting benefit to researchers.
