Abstract
A numerical controller controls a relative speed between a tool and a workpiece on the basis of a machining program. In a case where a corner part exists between a current block and a next block of the machining program, the next block is prefetched, and an allowable speed at the corner part at an end point of the current block is calculated. At least one of pre-interpolation acceleration of an acceleration part, a pre-interpolation speed of a constant-speed part, and pre-interpolation acceleration of a deceleration part that are relative speeds between the tool and the workpiece is adjusted so that the relative speed between the tool and the workpiece is maintained at a preset allowable speed while the corner part is passed through.
