Taguchi Method Based Optimization for Surface Roughness in Drilling Operation of EN-31 Steel Material and DOE Approach [ ]


Drilling is on the basic machining process of making holes and it is essentially for manufacturing Industry like Aerospace Industry, Automobile Industry and Medical Industry.In the present work by using Taguchi approach the End Milling of EN 31 Steel Alloy is carried out in order to Optimize the Milling process parameter and the Surface Roughness.A run order was devlop by using Three Milling Process parameter i.e. Speed,Feed Rate and Depth of cut.Each having Three levels using L9 Orthogonal Array.The Nine Experiment are perfomed and surface roughness is calculated the Signal to Noise Ratio (S/N Ratio) of predicated value and verification Test value are vaild when compare with the Optimum values.
