Optimization and the Effect of Controlled Parameters for Cutting Inconel 800 in WEDM

Abstract

Sophistication and quality of the products/parts are the major requirements of the customer in the present world. Therefore, the industries are searching for un-conventional machining processes to achieve desired production requirements. One among such production/machining processes is the Wire-Electro Discharge Machining. In this paper Design of experiment is carried-out considering Taguchi technique with four input parameters namely, pulse-on time (Ton), pulse-off time (Toff), and current (I) and servo voltage (SV). The objective of this project is to investigate the effect of those parameters on material removal rate(MRR) and over cut after machining ofInconel800andalso to analyse them icro-hardness at different subsurface distances from the cutting surface. Using parametric study regression equation for material removal rate and over cut are established to analyse the responses also obtained optimum MRR and overcut using Genetic Algorithm (GA), which is the most useful and popular optimization technique.
