Analytical Modeling of Tool Wear Progression During Turning Particulate Reinforced Metal Matrix Composites

This paper presents an analytical model for the prediction of tool flank wear progression during bar turning of particulate reinforced metal matrix composites. In this paper, a methodology for analytically predicting the wear progression as function of tool/workpiece properties and cutting parameters is presented. According to this approach, the wear volume due to two body and three body abrasion is formulated. Then, the flank wear rate is formulated by considering the tool geometry in 3D turning. Turning tests were carried out for a range of cutting speeds, tool nose radius and volume fraction of particles. The results showed good agreement between predicted and measured tool wear progression.
