本研究的目的是建立一种方法来估计，在真实的时间，加工误差所造成的振动的切削点的立铣刀。在切削试验过程中，测量了主轴转速从中速到高速时立铣刀刀柄处的振动位移和动态切削力。结果发现，当切削刃的径向方向垂直于进给方向时，在切削点处的振动位移在主轴速度为4500 rpm或更低时显示出与加工表面的高度良好的一致性。
The purpose of this study is to establish a method of estimating, in real time, the machining error caused by vibrations of the cutting point of an end mill. The vibration displacement at the shank of the end mill and the dynamic cutting force were measured during cutting tests while spindle speed was increased from medium to high. It was found that the vibration displacement at the cutting point at the moment when the radial direction of the cutting edge is normal to the feed direction showed a good agreement with the height of the machined surface at a spindle speed of 4500 rpm or less.
