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.
