Abstract
The use of hardened steel is increasing rapidly nowadays. Simultaneously the requirement for machining of hardened steel is also increasing. The present research work deal with the optimization of cutting parameters such as spindle speed, feed, depth of cut, MRR and surface roughness value for hardened steel by using Advanced Cutting Tools. Hence the present study use the high chrome steel bar as work piece and CBN 7025 tool with different shape of insert (like C type, D type, W type, T type etc.) and focused on the optimum value of material removal rate(MRR) and surface roughness(Ra) by using the taguchi L8orthogonal array and ANOVA analysis. The C type cutting insert gives the higher material removal rate and the T type cutting insert gives the higher surface finish and ANOVA analysis suggested that the depth of cut and feed are the main affecting factor for material removal rate and surface roughness
