Abstract

The objective of this paper is to investigate the effect of nose radius and tool shape on diameter error, circularity and surface roughness of turned parts during dry machining operation. The paper presents both analytical and experimental results of nose radius, tool shape and surface roughness of a turned material (alloy steel AISI-4340) in three different levels of control parameters that have been affected by nine cutting tool shapes of CVD TiN-TiCN-AL2O3-TiN, CVDTiN-MT-TiCN-AL2O3-TiN, and PVDTiAN Stellram; where the three tool shapes of cutting tools that have the same nose radius (0.4, 0.8, 1.2), and the feed rates are kept to be 0.11, 0.22, 0.33 in three levels, which are L1, L2, and L3, respectively. Therefore, Taguchi method and Pareto ANOVA analysis have been incorporated in this study to determine the analytical results. The controlled variables (speed of cut =212 mm/min and depth of cut= 1 mm) well be utilized in this study.
