A method for numerically controlling a machine tool comprises at least two tools which are arranged to move in unison with a constant position relationship with respect to one another. The tools are moved relative to a workpiece in accordance with absolute commands to machine in a prescribed manner. A single current position register, which is comprized a section for storing X coordinates and a section for storing Z coordiantes, is provided to store the current position of a first tool.
