Influence of Wiper and Conventional Inserts at Profile Geometry During Turning of D2 Tool Steel

Abstract

Latest inventions in the field of manufacturing drive the new technologies and different sources of production and to design the various sources to enhance the productivity as well as to reduce the cost, while maintaining the required specifications and high standards of the products. For achieving the production with high quality, tool manufacturers are continuously improving cutting edge, coating, geometry and the material of the tool. The tool geometry affects different aspects of tool like cutting temperature, tool wear and tool life, surface roughness, dimensional accuracy and surface integrity in the machining. The existing study is an attempt to explore the effect of wiper and conventional insets at profile turning. In this research inserts (wiper and conventional) having three different tool of nose radius (0.4, 0.8 and 1.2mm respectively) were evaluated at cutting speed (150m/min), feed rate levels (0.05. 0.10, 0.15, 0.20mm/rev), and depth of cut (0.2mm). Workpiece surface roughness (Ra) dimensional accuracy and microhardness of the machined surface were assessed. It was found that in profile turning in case of conventional inserts with larger nose radius of 1.2mm performed better than the other two inserts in term of surface roughness and dimensional accuracy. While in case of wiper inserts surface roughness and dimensional accuracy results were not better as comparing to conventional inserts. Microhardness under the machined surface was increased in both the cases of wiper and conventional.
