Abstract:

The remarkable high temperature strength, significant resistance to heat and fatigue of nickel-based superalloys lead to their wide application in the turbine sections of jet engines. However, their excellent performance is also accompanied by poor cutting ability, especially in the profile machining of structural parts. This paper first reviews the application of nickel-based alloys in turbine sections and the latest development of high efficiency grinding process. Then, the limits of high efficiency profile grinding (HEPG) are analyzed and the existing solutions are reviewed. Finally, a new strategy is proposed to further develop the potential of profile grinding in nickel-based alloys.

Key words: nickel-based superalloy, grinding, high efficiency profile grinding (HEPG), undeformed chip thickness, patterned form grinding wheel, grinding burn, profile accuracy
