    摘要： A cutting method in which, in cutting an inner circumferential face or an outer circumferential face of a work based on turning of a main shaft around a predetermined position serving as a center, control is enabled to make a cutting velocity constant accurately. To achieve the object, a cutting method is provided for an inner circumferential face or an outer circumferential face of a work, using a cutting tool projecting from a main shaft which turns around a predetermined position serving as a center and for which a turning radius is adjustable, wherein, in the case that a turning angular velocity of the main shaft is represented as ω, a distance from a turning center to a tip of the cutting tool is represented as R, and a cutting velocity of the tip of the cutting tool is set to a constant value C, making the cutting velocity of the cutting tool is made constant by performing control such that ω changes in association with a change in the distance R so that ω = C 2 − R ˙ 2 1 2 / R is formulated (where Ṙ denotes a time differential of the distance R), thus providing an even cut face.

    摘要翻译： 本发明提供一种切削方法，该切削方法在将以规定位置为中心的主轴的旋转作为中心对工件的内周面或外周面进行切削加工时，能够进行正确的切削速度控制。 为了实现该目的，使用从以预定位置为中心转动的主轴突出的切削工具对工件的内周面或外周面进行切削加工， 其中，在主轴的转动角速度被表示为ω，从转动中心到切削工具的尖端的距离被表示为R，并且切削工具的尖端的切削速度 被设定为恒定值C，通过进行控制，使ω与距离R的变化相关联地变化，从而使切削工具的切削速度恒定，从而形成ω= C2-R·212 / R（其中 Ṙ表示距离R的时间差），从而提供均匀的切割面。
