In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

在断续切削中,铣削波形可被看作周期函数,将单齿铣削波形看成为脉冲函数,经过傅立叶变换,可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成,讨论所获得的频谱函数,是研究三维复杂槽型铣刀片切削性能的主要环节,以便了解影响单齿铣削波形幅值谱图的各种因素,并从功率谱图的组成情况来考察动态铣削波形的特性,从而进行槽型的设计和优选。
