Research on Cutting Temperature of GH4169 Turning with Micro-Textured Tools

The GH4169 superalloy has the characteristics of high strength, strong thermal stability, large specific heat capacity, small conductivity, etc., but it is also a typical hard-to-cut material. When cutting this material with ordinary tools, force large, and temperature high, which leads to severe tool wear short service life. In order improve performance tools when GH4169, reduce temperature, extend life tool, micro-textured were used cut in spray cooling. effects micro-texture morphology dimensional parameters on analyzed. Firstly, micro-textures five different morphologies designed near nose rake face cemented carbide tools. three-dimensional models established by using ABAQUS, simulation analysis was carried out. Compared non-textured lowest selected according results temperature. Secondly, based optimized morphology, size designed. simulated analyzed, as well. Finally, processed applied experiments. model verified experiments, influence This paper provides theoretical reference basis for design application
