Radial over cut optimization of titanium alloy for electric discharge machining using advanced optimization technique – Jaya algorithm

Abstract

In this work, EDM parameter optimization is done to minimize radial overcut. Response surface methodology is used to develop a predictable mathematical model for radial over cut (ROC). The current, voltage, pulse on time and duty factor are selected as a process control parameters, radial over cut (ROC) is considered as quality measures. Central composite design (CCD) is used for the design of experiments. Total of thirty experiments were conducted as per the design of experiments (DOE). A mathematical model shows the relation between the machining parameter and ROC. This mathematical model used to optimize ROC using Jaya Algorithm an advanced optimization technique.
