Abstract
In view of the lack of researches on the influence of micro textures on the cutting performance of milling cutters, this paper studies the cutting performance of the micro-textured ball-end milling cutter, taking the distance from the cutting edge and the offset angle as the influencing factors, and through the comparative test with non-texture cutters, studies the cutting performance and formation of the chip. The results showed that when micro textures are close to the cutting edge, the milling force is larger, while the offset angle had no significant effects on the milling force. The optimized micro-textured parameters are 120 μm and 0.3°. Compared with the non-texture cutter, the micro-textured cutter had better effects of anti-wear and anti-friction, as well as surface quality of the workpiece. The deformation is more serious when the chip passes the rake face. This paper has some guiding significance for the preliminary design of micro-textured cutters.

Advanced cutting technology, represented by high performance cutting, has been developed rapidly and widely used in key development fields such as aerospace and energy equipment. Titanium Alloys with good thermal strength, high specific strength, corrosion resistance and other excellent properties are widely used in integral bladed disks, casings and key components of aircraft. When titanium alloys are prepared, the high cutting temperature, the large milling force, and the serious cutter wear are the common problems in the machining of these parts. These problems lead to shortened cutter life and adverse effects on the integrity of the surface of the parts. Through researches, micro textures with certain regular arrangement is prepared on the surface of friction pair [1, 2]. This method can significantly improve the friction performance of the contact surface of the friction pair and improve the surface quality of the workpiece. As a method to improve the reliability and service life of mechanical parts, microtextured cutting cutters have achieved preliminary success, so they have q
