高硬度航空合金铣削颤振研究进展

高硬度、高强度合金在航天航空领域的应用越来越广泛,但这类合金在铣削过程中存在铣削力过大而容易引起刀具颤振的问题,而刀具颤振会降低工件的最终表面质量和生产效率。为了减少刀具颤振对加工质量的影响,铣削颤振稳定性预测被广泛应用于高硬度合金铣削的研究中。综述了高硬度航空合金铣削过程颤振稳定性分析的研究现状,重点阐述再生型颤振的动力学建模,分析刀具颤振与磨损的相互关系,介绍了近年来铣削颤振稳定性研究中抑制颤振的研究成果。

Research Progress on Milling Vibration for High-hardness Aeronautical Alloy

High-hardness and high-strength alloys are more and more widely used in aerospace field. However, in the process of milling the alloy, there is a problem that excessive milling force can easily cause tool vibration, which can decrease the final surface quality and production efficiency of the workpiece.In order to reduce the effect of tool vibration on machining quality, stability prediction of milling vibration is widely used in the study of high-hardness alloys milling.The research status of vibration stability analysis in high-hardness aeronautical alloy milling process was reviewed, the dynamic modeling of regenerative type vibration was emphatically expounded, the relationship between tool vibration and wear was analyzed, and the research results of vibration suppressionin milling stability research in recent years were introduced
