Abstract GH4169 superalloy has excellent properties such as high strength, high
hardness and high temperature resistance, and is widely used in aerospace, automobile manufacturing, defense industry and biomedical fields. In the cutting process
of superalloy, there are some problems such as serious tool wear and poor surface
quality. The placement of micro-pit arrays on the rake face of cemented carbide tools
can effectively improve the friction and wear resistance of the tools and improve
the cutting conditions. In this article, ABAQUS software is used to simulate the
micro-pit array tool orthogonal micro-cutting GH4169 superalloy. The cutting simulation of GH4169 superalloy was carried out by using micro-pit diameters of 35 µm,
30 µm, 25 µm, 20 µm and non-texture, respectively. The cutting-chip contact state,
cutting force, cutting temperature and chip shape during the cutting process were
analyzed. The study found that the placement of micro-pit texture can effectively
reduce the cutting force during cutting and improve chip breaking. The micro-pit
texture can intercept debris and hard particles on the bottom surface of the chip,
reducing scratches on the rake face of the tool and the furrow effect of the hard
particles, effectively improving the wear resistance of the tool.

11.1 Introduction
With the rapid development of aviation manufacturing industry, the application of
superalloys is more and more extensive [1–3], which is mainly due to its good wear
resistance and excellent structure [4–6]. Under the condition of high temperature
and high pressure, the superalloy can still maintain high tensile strength and yield
strength, and has low creep and high corrosion resistance and oxidation resistance
