Abstract
A machine tool includes a tool post having a tool unit for machining a workpiece, operation control means for controlling the operation of the tool unit in accordance with a plurality of commands described in a numerical control program and movement limiting means for inhibiting entry of the tool unit into a no-entry region. The plurality of commands include a limit value setting command for calculating a limit value of a position of the tool unit avoiding interference with a machine element located within a movable region of the tool unit and for determining the no-entry region by the calculated limit value. Upon reading the limit value setting command out of the numerical control program, the operation control means calculates the limit value and determines the no-entry region by the calculated limit value.
