Abstract

The research is designed to explore the influence of process parameters during the wire EDM of tapered Steel blanks. Tapered steel blanks with angles of 30°, 45° and 60° are machined and slots are generated in blanks using the wire EDM process. Taper angle, current and pulse-off time are considered the controllable process parameters for this study, whereas, other controllable parameters are kept constant. Effect of these controllable parameters over kerf width, surface finish, MRR and wire are examined using the analysis of variance technique. Regression models for the four response variables are also developed, relating the variables with the varying controllable parameters. Multi-variable optimization of controllable parameters is performed using the Genetic Algorithm for the favourable response variables.
