Abstract

In this study, the prediction of surface roughness of milled surfaces was carried out
using Taguchi Method with four inputs, namely, cutting direction, stepover, feed per
tooth and workpiece surface geometry. A systematic approach to obtain an optimal
surface roughness was employed to consider the effects of Taguchi method for this
application using CNC milling machine with ball mill cutter. The results show that the
Taguchi method is an effective tool in predicting the optimum factors to obtain
minimum surface roughness, which are stepover, surface type, feed per tooth and
cutting direction respectively.
