Abstract
Machining vibration is one of the most important reasons that influences the tool life, machining efficiency and the final surface quality, the performance and the reliability of aero-engine is affected directly by compressor blades. To restrain machining vibration of compressor blade in multi-axis machining, the mechanism of vibration and milling force during machining thin-walled blades is analyzed. A model of machining vibration and a vibration differential equation are established. Response function of blade reflects that the amplitude is influenced by clamping stiffness of blade, the natural frequency and damping of blade-fixture system. The paper presents a method of tension clamping to increase stiffness and natural frequency of system. Experiments show that the method can reduce clamping deformation, increase blade stiffness and natural frequency of blade-fixture system. It can reduce machining vibration eventually.
