Theories And Experiments Of Plunge Milling Cutting Force And Temperature On Titanium Alloy

This paper has concluded the machining characteristic and merits of plunge milling and deeply researched on the cutting force,cutting temperature, cutting vibration. Aimed at cutting material Titanium alloy, some experiments and analysis have been done to indicate the Adiabatic shear theory and the shortening coefficient of chip has been calculated. In order to test the cutting force during plunge milling process, data acquirement and analyze system and hardware platform have been established. The experimental equations of cutting force are formulated according to the experimental data. Then the relationships between cutting parameters and cutting force are analyzed. The stability in cutting process is an advantage of plunge milling, which has been proved by vibration experiments. It is well known that the vibration directly influences the surface roughness. The result of roughness tester showed good roughness. Ignoring the vibration in milling process, the mathematical model of cutting force is established according to the orthogonal cutting theory and experimental data. It can be concluded from the comparison between simulation results and experimental results that the simulation result is reasonable. The stress and displacement filed on the insert are analyzed by ANSYS software. The results are consistent with insert's wear, which support the optimization of insert. In the end the measurements and experiments on the cutting temperature are investigated.
