Optimization Of End Milling Parameters For Improving Surface Roughness Using Taguchi Method
Present paper presents a study that investigates the effect of the end milling machining parameters on the surface
roughness of the EN 31 steel. Nine experimental runs based on an orthogonal array of Taguchi method are performed and it
is subsequently applied to determine an optimal end milling parameter combination. Surface roughness is selected as the
quality target. The end milling machining parameters considered are rotational speed, feed rate and depth of cut. The feed
rate is found to be the most dominant parameter for surface roughness of EN 31 steel. Present study shows that high spindle
speed with small feed rate produce better surface finish and the effect of depth of cut is found to be negligible. Taguchi
method is used to obtain the optimal combination of end milling parameters.
