Abstract"The study is aimed to investigate certain aspects of high-speed machining for improving the accuracy of thin-walled aerospace components. The approach used involved the development of finite-element model of the workpiece to be machined and its subsequent frequency response analysis. The response of the workpiece subjected to dynamic cutting force gives an indication of the best possible speeds from the point of view of accuracy. Based on the results of the analysis, it is possible to predict the range of spindle speeds at which the workpiece demonstrates very high dynamic rigidity. In addition, this study has established the superiority of high-speed machining to produce aerospace structures with high stiffness-to-weight ratio and also throws some light on the capability of high speed in machining of low rigidity sculptured-surface components.
