一个内钻是由一个侧面锁定装置夹紧。通过这种钻头获得的孔的形状被发现是扭曲的椭圆形。傅立叶分析表明，孔的不圆度是由于钻头上产生的离心力的谐波变化。主轴转速的抖振范围也显示在一个稳定性图中，表示系统的频率响应。
An endrill is clamped by a side-locking device. The shape of a hole obtained by such a drill is found to be of a distorted oval shape. Fourier analysis of the process reveals that the out-of-roundness of the hole is due to the harmonic variation of the centrifugal force developed on the drill-bit. The chattering ranges of the spindle speed are also shown in a stability chart representing the frequency response of the system.
