Mathematical Modeling and FEA of Temperature Field in Plunge Milling Ti Alloy

In this essay,at first through analyzing the cutting-heat in the process of plunge milling Ti-Alloy from the metal cutting theory,the heat conduction equations of work piece were concluded,and the mathematical model of the titanium plunging was established on this basis.Then calculating the heat conductionequation in FEM,and using Matlab for numerical simulation,we get the temperature distribution of work piece.Finally comparing the numerical results with experimental data,we can verify the accuracy and reliability of the finite element model.It will be an important reference to the cutting parameter optimization and tool design in the process of titanium plunge milling.
