An Investigation of Flank Wear Land Inclination in Orthogonal Machining

Abstract

The sharp freshly ground tool forms wear land with machining. The present work attempts to measure the non-zero inclination of flank wear land with respect to cutting direction and study the effect of the machining parameters, like speed, feed, rake angle and clearance angle, on the formation of non-zero flank wear land inclination. The experimental plan was based on the face centred, central composite design (CCD). The results clearly indicated the presence of non-zero flank wear land inclination with the direction of cutting. The interactions between machining parameter strongly influences flank wear land inclination. This information may be helpful in improving existing machining model or to develop a new model.
