In the milling of titanium alloy, the distribution of milling force and its related law of change seriously affect the physical properties of workpiece materials, the stress distribution on a cutter’s rake face and the interaction between the workpiece, the cutter and the chip. This article reports on a study of the stress field distribution under the conditions of anti-friction and anti-wear when cutting titanium alloy with a micro-textured ball-end milling cutter. Milling test data were used to establish empirical models of milling force and the contact area between the cutter and the chip. Based on this, the force density function of the cutter coordinate system was obtained and the equivalent stress and displacement of the cutter were simulated and analyzed. This in turn provided the means to acquire the instantaneous stress and strain relating to the cutter at any time. Analysis of the simulation results shows that the position in which the stress and strain are concentrated on the cutter is consistent with actual processing. This confirms the accuracy of the force density function and provides the basis for further study of thermo-mechanical coupling behaviors when engaged in using micro-textured ball-end milling cutters for the cutting of titanium.

In this paper, a cutting force model in ball end milling of mold cavity corner is established. Based on infinitesimal milling force model, cutting element of ball end milling cutter is treated as equal diameter end milling cutter, then determine the location of points when the micro-element participated in the cutting, and the tool-workpiece contact area and cutting range is determined. Thereby a complete milling force model in corner machining with ball end milling cutter is established.

During the process of micro machining, the existence of tool runout not only aggravates the wear and breakage of the cutter, but also seriously affects the surface quality of the parts. In order to observe the runout of micro-milling cutter, a detection method based on machine vision was proposed in this paper, which can calculate the tool runout by measuring the maximum value of external fluctuation of the cutter assembly near the tool tip. The proposed method can realize the direct measurement of radial runout of a micro-milling cutter. A dedicated prototype measuring system was established, which includes an on-machine measurement unit, a controller and the software. To obtain the images of maximum profile of the cutter at different angles, the cutter should be perpendicular with the optical axis of camera lens in the on-machine measurement unit. The experiments verified that the proposed method is feasible and the developed measurement system can fulfill the needs of industrial applications.

When precision cutting titanium alloy, the cutting part of cutting tool is mainly concentrated in the cutting edge area, so there is a strong emphasis upon the cutting edge’s geometric parameters. Studies have found that putting a micro-texture on the cutting surface can reduce the cutting force. This article looks at the milling force involved in cutting titanium alloy with a micro-textured ball-end milling cutter with different shaped cutting edges. First, a milling model relating to different cutting edges is established based on the traditional model of milling force. Then, the effects of different cutting edge geometry parameters and micro-texture parameters on milling force are simulated and tested using a finite element method. With milling force serving as the evaluation index, the optimum micro-texture parameters for a blunt circular cutting edge are a micro-pit diameter of 40 μm, a distance between micro-pits of 175 μm, a distance from the cutting edge of 110 μm, and a blunt circle radius of 60 μm. For a negative chamfer edge, the optimum parameters were a micro-pit diameter of 50 μm, a distance between micro-pits of 175 μm, a distance from the cutting edge of 120 μm, an edge width of 200 μm, and an edge angle of 10°.
