Paper Title:
Finite Element Analysis of the Effects of Tool-Chip Friction on Cutting Temperature Field
  Abstract

The heat generation caused by tool-chip friction and chip deformation strongly influences the tool wear and tool life in metal cutting processes. The focus of this paper is on the effect of tool-chip on cutting temperature field. A series of ¬finite element simulations have been performed, in which a modifi¬ed Coulomb friction law is used to model the friction along tool–chip interface. A tool rake angle ranging from 10° to 45°, a inclination angle ranging from 0° to 20°, and a friction coefficient ranging from 0.1 to 0.6 have been considered in simulations. The results of these simulations show that the maximum cutting temperature increases with the increasing of tool-chip friction coefficient at different rake angle and inclination angle. The form of tool wear mainly appears as crater wear when the friction coefficient is less than 0.5, and the cutting edge tends to split when the friction coefficient is larger than 0.6.
