ABSTRACT:
An apparatus for cutting an inner circle in a workpiece with a cutter of a numerically controlled machine tool linearly moves the cutter from the center of an inner circle in the workpiece in a radial distance according to an initially cut radius I, and cuts an inner circle in the workpiece according to a radial depth of cut K until a finally cut radius J is reached. As other command parameters, there are supplied an initial workpiece radius P which indicates the minimum distance from the center of the inner circle in the workpiece to the workpiece, and a cutting feed starting distance SN that the cutter starts to move at a cutting feed rate across the initial workpiece radius P before reaching the workpiece. The length of a linear path that the cutter linearly moves is compared with the initial workpiece radius P, a feed rate at which the cutter is to move along the linear path is determined depending on the result of comparison between the length of the linear path and the initial workpiece radius P.
