  • Machine tool
    Patent number: 11919093
    Abstract: A machine tool includes a plurality of modules, and a control means for controlling operation of the modules, wherein the plurality of modules include a fixed module and two movable modules. The control means includes a restriction means for restricting the movement of the two movable modules for allowing only one of the movable modules to be moved to a facing position facing the fixed module; and a determination means for determining the movable module to be moved to the facing position. The control means is configured to control the operation of the plurality of modules so that, when the operation under cooperation of the fixed module and one of the movable modules has been completed, the restriction means releases the restriction of the movement of the other movable module to the facing position.
