High-Speed Cutting Machining Simulation of Aero Engine Casing Hole

Abstract

For the high-speed machining aero engine casing hole, according to the principle of metal forming and the characteristic of metal cutting plane strain, with selecting some key physical factors of the cutter - chip contact friction and abrasion model, the Cartesian orthogonal cutting model of aero engine casing hole was established by using the Deform, a sort of finite element analysis software. With taking cutting temperature for preferred aim of the cutting parameters, select the appropriate cutting parameters, the aim of aero-engine casing high-speed (cutting speed up to 700m/min) cutting has been achieved by simulation, and the feasibility of the cutting process was researched and confirmed in theoretically by analyzing the cutting force, cutting temperature and tool wear condition.
