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.
Claims3
A machined tool comprising:
- a workpiece holder means for holding a workpiece, a plurality of modules for performing a predetermined processing on the workpiece, and a control means for controlling the operation of the plurality of the modules;
- the plurality of the modules comprising:
- a fixed module that is movable in a first direction and is immovable in a second direction orthogonal to the first direction;
- and two modules that are movable in the first direction and the second direction and adapted to be arranged in parallel with each other on opposite side of the fixed module so as to face the fixed module;
- the control means comprising:
- a restriction means for allowing only one of the two movable modules to be moved to a facing position to the fixed module, by restricting the movement of the other movable module;
- and a determination means for determining the movable module to be moved to the facing position relative to the fixed module based on the predetermined processing;
- the restriction means being configured to control the operation of the plurality of modules so that, when the processing under cooperation of the fixed module and one of the movable modules determined by the determination means has been completed, the restriction of the movement of the other movable module to the facing position is released.
