识别无颤振切削条件，颤振稳定性波瓣，需要测量安装在主轴上的每个刀具的频率响应函数（FRF）。本文提出了一种方法，组装已知的动力学主轴刀具保持器与解析建模的立铣刀使用的容抗耦合技术。经典的接收技术是通过提出一种方法来识别端铣刀主轴/工具保持器联合动力学，其中包括平移和旋转自由度的增强。该方法需要测量FRF，并对主轴-工具保持器组件和连接到主轴的空白校准圆柱体进行冲击测试。从两个实验中完全识别出主轴和保持器的特性，并用于任意尺寸立米尔斯铣刀的频响函数的数学预测。所提出的方法是实验证明和验证在切削试验。(C)2003爱思唯尔科技有限公司。保留所有权利。
Identification of chatter free cutting conditions, the chatter stability lobes, requires a measurement of the frequency response function (FRF) of each tool mounted on the spindle. This paper presents a method of assembling known dynamics of the spindle-tool holder with an analytically modeled end mill using the receptance coupling technique. The classical receptance technique is enhanced by proposing a method of identifying the end mill-spindle/tool holder joint dynamics, which include both translational and rotational degrees of freedom. The method requires measurement of FRFs with impact tests applied on the spindle-tool holder assembly and blank calibration cylinders attached to the spindle. The spindle and tool holder characteristics are completely identified from the two experiments, and used for the mathematical prediction of FRF for end mills with arbitrary dimensions. The proposed method is experimentally proven and verified in cutting tests. (C) 2003 Elsevier Science Ltd. All rights reserved.
