Modelling and Numerical Simulation of Cutting Stress in End Milling of Titanium Alloy using Carbide Coated Tool

The mechanistic force models were introduced in high accuracy force predictions for most applications. Experiment was made for the milling of titanium alloy by coated cemented carbide cutting tool. Based on the cutting force theory, test results and finite element method, we can get the expression of resultant cutting force accurately, which can be developed to a big cutting database. According to the analysis, the maximum deformation and effective stress showed an increasing trend for the machining with end-milling cutting tool. A reasonable set of milling parameters for the machining of titanium alloy by coated cemented carbide cutting tool was obtained by analyzing the cutting efficiency in relation to cutting force of the tools. It is expected that this study would provide a fundamental basis for the optimization of the cutting parameters for titanium alloy.
