GH4169 nickel-based superalloy material has the characteristics of high hardness,high temperature resist-ance,corrosion resistance and so on,in order to avoid the flutter between the tool and the workpiece in the process of turn-ing,the surface quality after machining is affected.Based on the characteristics of workpiece to be processed,the dynamic model of workpiece-tool system in external circular turning is established and conduct stability analysis.The results show that GH4169 nickel-based superalloy with good surface quality can be obtained when the main deflection angle is about 93°.This study provides a basis for the selection of the main deflection angle of the tool for machining materials with high hardness and which are prone to chatter during machining,such as superalloy.
