Abstract:
 Abstract:In the boring process the boring bar in the cantilever state is used, which reduces stiffness of the boring bar Vibration is easy to be occurred, and the vibration affects the machining precision and surface quality When the vibration is serious, it may lead to scrap How to reduce the vibration in the boring process is a key problem to be solved This paper presents a new boring bar with a variable mass dynamic vibration absorber (VMDAV) based on dynamic vibration absorber theory The dynamic model of the new boring bar system is established The influences of the excitation frequency and the mass of the VMDVA on the vibration reduction characteristic are discussed A new vibration reduction method is proposed by adjusting the mass of the VMDVA to achieve the optimal vibration reduction performance Finally, the vibration reduction performance of the new boring bar is verified by analyzing the displacement of the main system under different mass of VMDVA These works could provide guidance for designing new types of boring bars, selecting cutting parameters, adjusting the vibration reduction performance of the proposed boring bar, and as a result, it provides a new idea for the design of boring bar
