Abstract

Selection of parameters and its range is quite important to proceed with the major experimentation in research work especially when we use Taguchi method. In any machine, few parameters should be considered as static and few as dynamic according to the limitations or ranges of the values of parameters in that machine. After the completion of selection of parameters, the immediate next task is to select the range of values. Along with the study of the literature, there should be one procedure or base to select the correct range of values in the set. Here, in this paper the selection of range of values of discharge current is discussed. Out of the four input parameters which are proposed to be used in the major/main experiment, three parametric values are assumed as static and five experiments were conducted to determine the range for the fourth parameter. As a result of five experiments, output parameters MRR and SR were found out for the five set of input values. Modified TOPSIS has been applied on these observations and better values of DC were found out with higher relative closeness in the method, to proceed with the main experiment using Taguchi.

Keywords
