摘要：

To enhance the stiffness in multi-axis machining of thin-walled compressor blade to suppress vibration, an on-line stiffness enhancement method based on axial force control was developed. Mathematical derivation shows that the action of axial clamping tension force will reduce the deflection of the workpiece and enhance the stiffness. Based on the derivation and analysis results, an on-line stiffness enhancement device was developed for compressor blade machining. Different tension force were applied in the axial direction and frequency-amplitude relationships were obtained. Initial experimental results show that the proposed method can enhance the system stiffness in multi-axis machining of thin-walled blade. It can be further developed to get full control of the machining process. (C) 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
