Study of Different Micro Milling Blades on Milling Titanium Alloy TC4

With the development of micro-miniature, micro-milling technology has been widely used. Due to the difference in workpiece materials and processing technology, the selection of the edge structure of the micro- milling cutter during processing is particularly important. This paper analyzes the influence of micro-milling of titanium alloy TC4 on cutting force, cutting heat and tool stress distribution for micro-milling cutters with a diameter of 0.1mm based on Definite-3D, ANSYS and other finite element simulation software.The results show that the spiral-edge micro-milling cutter can effectively reduce the cutting force and cutting heat compared with the straight-blade micro-milling cutter. Considering the rigidity, strength, cutting performance and practicability of the tool, the traditional double-edged spiral-edge micro-milling is still the best choice. The research results of this paper can provide a theoretical basis for the design of micro-milling tools.
