摘要:

镍基高温合金因其优异的高温强度、热稳定性和抗疲劳特性,被广泛应用于航空发动机的核心部件,该材料机械加工性差,成型加工更加困难。本文阐述了镍基高温合金高效磨削工艺的研究现状,找出了成型磨削加工应用中存在的瓶颈,并对现有的解决方法加以剖析;提出以确保成型面具有相同单颗磨料切厚为目标优化成型砂轮磨粒排布,并与高效深切磨削工艺(HEDG)相结合的构想,以达到进一步挖掘高效成型磨削技术在航空难加工材料成型加工中潜力之目的。

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
