In the process of highspeed milling superalloy GH2132, the tool wear is serious and the tool life is short. Under certain conditions,the coated tool can generate a wearresistant or selflubricating oxide film layer in the stable wear stage, that is, selforganization structure, which can improve the cutting performance, delay the wear and prolong the service life of the tool. Based on this, selforganization structure on coated tool surface in high-speed milling was studied to improve tool life. The results show that in highspeed milling superalloy of GH2132, the stability existence conditions of surface self-organization structure of PVD-AlTiN carbide cutting tools are Fx=90~105 N, Fy=115~168 N, Fz=410~510 N,σs=-735~-873 MPa.The results provide reference for coated tool milling superalloy and contribute to green intelligent manufacturing.
