详细分析了利用五轴可倾式转台加工圆锥体的数控数据。为了检测锥体的加工精度，采用五轴联动铣刀对锥体进行加工。然而，NC数据必须与转盘上的工件的设置位置相对应地改变。通过改变圆锥体的顶角和中心位置，分析了各轴的运动范围和速度。分析结果表明，顶角越大，各轴的运动范围越大，运动速度越高。当中心位置沿Y方向移动时，每个反转点都独立地显示在圆形路径上。因此，建议将圆锥体的中心位置沿Y方向偏移，以获得较大的运动范围和较高的轴向速度。
NC data for machining the cone-frustum by means of five-axis machining centers with a tilting rotary table are analyzed in detail. The cone-frustum is machined by using a milling cutter at simultaneous five-axis control for inspecting the machining accuracy. However, the NC data have to be changed corresponding to the setting position of the workpiece on the rotary table. Thus, the moving range and velocity of each axis are analyzed by changing the apex angle and center position of the cone. It is found from the analyzed results that the larger apex angle gives the larger moving range and the higher velocity to all axes. When the center position moves along the Y-direction, every reversal point independently appears on a circular path. Therefore, it is recommended to offset the center position of the cone frustum along Y-direction to give the large moving ranges and the high velocities to the axes.
