摘要
零件精加工过程中,颤振现象时有发生,为了避免加工过程中的颤振,提高零件加工质量,以镗刀杆为例,通过理论分析先确定影响镗削系统稳定性的因素,根据影响因素,设计了一种减震刀杆,通过改变刀杆的材料改变刀杆的静刚度和通过增大镗杆内部阻尼来提高刀杆动刚度进而实现减震目的,最终制造了减震刀杆,并通过切削试验验证,减震效果明显。
In parts precision machining process, flutter phenomena occurs. In order to avoid flutter in the process, the machining quality of the parts should be improved. Taking boring bar as an example, through the theoretical analysis, the factors affecting the stability of the boring system is determined. According to the influencing factors, a shock absorber is designed. By changing the material, static stiffness is changed. By increasing internal damping, dynamic stiffness is improved and shock absorption is realized. Ultimately the shock absorber is created and verified by the cutting tests with obvious damping effect.
