Influence of Cutter Orientations on Cutting Force in Ball End Milling of TC17

Abstract

In order to improve the ball end milling multi-axis milling titanium alloy workpiece machining method, the influence of cutter orientations on cutting force is studied in this paper by experiment. This paper uses the tool rotation angle and the tool inclination angle to describe the cutter orientations. Analyse the cutting force under different milling posture. The results prove that, when the tool inclination angle is constant, the change of tool rotation angle will cause changes in the value and direction of the cutting force. Though maintain the tool rotation angle, the change of the tool inclination angle will change the cutting speed, thus make the cutting force decrease first then increase.
