Evaluation of optimal responses in Monel 400 alloy using computer based unconventional machining process

The unconventional machining is an essential role in metal forming process. The dimensional accuracy and super finish are the main features of modern machining methods. Electric discharge machining is a competent process to any materials and composites. In this article is used to machining characteristics of Monel 400 alloy with monitored by computer networks. The response variables are mainly depending on input variables and their levels. Taguchi method is utilized to evaluate the optimal control factors. The mean and SN ratio is evaluated by based on the criteria of the responses. The involvement of control variables to the responses have been validated by variance analysis. The best possible MR was attained at a discharge current of 40 A, pulse on time of 140µs, and spark voltage of 25 V.The finest RTW and SR was occurred at a discharge current of 40 A, pulse on time of 140µs, and spark voltage of 20 V. The scope of the work is to maximize the metal removal and minimize the tool wear.
