Abstract
The objective of this paper is to present a methodology to analytically model the tool flank wear rate in near dry turning under built-up edge (BUE) effect. It involves the analysis of cutting forces, cutting temperatures and tool wear modes of abrasion, adhesion, and diffusion. The BUE formation is also considered in the view of the dynamic strain aging in the modified Oxley's model. The important factors related to this model are contact stresses and temperatures that are obtained from the cutting force model and the cutting temperature model. To develop these models, a set of cutting experiments using carbide tools on AISI 1045 steels are performed to calibrate the coefficients in the models and to verify the proposed flank wear mechanisms. The comparisons between the model-predicted flank wear and experimental results show that the flank wear in near dry machining can be estimated well by the proposed models.
