Wear studies in hard turning of high-chrome white cast iron using ANOVA and RSM techniques

Abstract

In these days, tool wear is a major concern in hard turning process. Though the hybrid machining and thermally enhanced machining methods relieved the burden of the Industry to some extent, tool wear studies are more vital in order to improve the productivity. This research work mainly focuses on such studies wherein the influence of cutting parameters and tool temperature on tool wear are investigated both experimental and analytical procedures. The work material selected for the process was high-chrome white cast iron (HCWCI) and cutting tool as multi-layer hard coated carbide inserts. The experimental trials were carried out in accordance with the Taguchi's techniques. Second order regression was established to build the linear relationship among the process parameters and its responses. The research study reveals that flank and crater wear are the dominant wear patterns appeared in the process. The influencing parameters and their interactive effects on tool wear are also presented in graphical form which may useful while choosing the process parameters for better tool life. © 2020 Author(s).
