An inclusive discussion about chip shape during turning of the Nimax steel

Abstract

–In this study, Taguchi method was used to determine the cutting parameters for pre-hardened mold steel Nimax turning process. After completing the experiments which carried out with three different cutting speed, feed rate and depth of cut values, chips were collected for further analysis. As known, chips reflect the machining characteristics about the cutting material and give information about the cutting tool condition and its wear situation in some way. Therefore, analysis of the chips is an important issue in machining operations. It is aimed in this approach to put light for chip formation and its basic mechanisms during turning of the mold steels. This kind of study may be helpful for academic studies and industrial applications.
