The proposed approach to model stresses in cutting tools leading to evaluation of tool temperature distribution, and to eventually model the combined thermo-elastic stress state, is primarily intended for the development of efficient cutting tools rather than process control. The highlights of the approach are the semianalytical modeling of the tool-chip and tool-work contract stresses and friction, incorporation of the role of the secondary shear effects (albeit empirical) and the use of finite element method (FEM)-based estimation of the elastic (2-D) stress field. The contact stress information is used subsequently to model the temperature distribution in the tool. This approach was successfully evaluated in the case of single point turning tools using results from the experimentally measured temperature field in the tool based on the Binder Phase Transformation (BPT) technique. The temperature distribution in the tool for both dry and wet conditions as predicted by the FEM approach agreed quite well, in general, with experimentally obtained isotherms. Deviations in the observed results in the vicinity of the flank region appears to be related to the simplifications used in modeling the contact stresses therein. |
