Cutting method for inner circumferential face or outer circumferential face of work

Abstract

A cutting method in which, in cutting a circumferential face of a work, control is enabled to make a cutting velocity constant accurately by 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 constant by performing control such that ω0 changes in association with a change in the distance R so that ω=(C2−{dot over (R)}2)1/2/R is formulated (where {dot over (R)} denotes a time differential of the distance R), thus providing an even cut face.
