摘要
The role of lead inclusions and the effect of depth of cut and tool rake angle on the chip formation process of an annealed bearing bronze (CAD 932) were investigated under dry, orthogonal machining conditions. It was found that when machining with large depths of cut and high tool rake angles, a crack developed just ahead of the tool cutting edge. This result was interpreted in terms of the direction of the thrust force and the presence of lead inclusions in the work material. It was also found that during the machining operation, lead particles were squeezed out of the material in the primary and secondary deformation zones and deposited on the tool rake face and on the chip underside surface. The shear stresses in the primary and secondary deformation zones were found to be independent of the depth of cut and tool rake angle. © 1990.
