摘要：

In this work, machining of Ti-6246 was carried out on EDM using graphite electrode using EDM oil dielectric. The process variables selected were current, pulse on-time and pulse off-time. Design of experiment was based on Box-Behnken Design of RSM technique. Optimization was conducted through desirability approach. Machinability of Ti-6246 work material was evaluated with regards to surface roughness, as better surface quality is requirement for every machined component. It was found that the optimum set of current, pulse on-time and pulse off-time were 4.5A, 50.07 ms and 100 ms respectively. The optimized response parameter achieved was surface roughness of 0.99 mm. Confirmation test were conducted at optimized variables and the value of surface roughness of 1.01 mm was obtained. Values obtained by multi-response optimization and the values obtained by confirmation test were observed to be approximately same. ? 2021 Elsevier Ltd. All rights reserved.
