Abstract

Materials with hardness more than 45 HRC are widely used in the manufacturing segments. To attain the prerequisite surface finish, industries rely on conventional grinding process. Elimination of this time intense procedure has become the need of the situation. Recent developments in manufacturing industries led to hard turning which gratify this requirement. In this study, turning of oil hardened non-shrinkable steel with PVD TiN coated ceramic insert is investigated. Optimizations of process parameter like cutting speed, feed and depth of cut resulting in better surface finish and material removal rate are established. Most desirable parameter values are projected by using grey relational analysis supported by Taguchi's L27 orthogonal array and analysis of variance.
