摘要：

In this paper, a thermomechanical modelling of the material flow is developed, and the tool-chip contact length and the sliding-sticking zones are characterised analytically. Furthermore, the finite element method is used to solve the non-linear thermal problem in the chip. The effect of cutting conditions and material behaviour on the sliding-sticking zones and on the temperature distribution and local friction along the tool-chip interface is evaluated. It has been found that the sliding-sticking zones strongly control the local conditions of stress, velocity and temperature. A qualitative comparison between the proposed model and experimental results is provided. (C) 2011 Elsevier Ltd. All rights reserved.
