Abstract
A machine tool including a tool holding unit and a workpiece holding unit includes: a clamper to which a part of a sub-tool, which is a separate tool from a main tool held by the tool holding unit alone, can be detachably connected; an attachment/detachment unit to which another part of the sub-tool can be detachably connected; a tool spindle that moves the clamper; an in-machine robot that moves the attachment/detachment unit; and a controller that controls driving of the tool spindle and the in-machine robot, to execute machining of a workpiece by the sub-tool.
Claims11
A machine tool including a tool holding unit and a workpiece holding unit, the machine tool comprising:
- a first connection unit to which a part of a sub-tool, which is a separate tool from a main tool which is held by the tool holding unit alone, can be detachably connected;
- a second connection unit to which another part of the sub-tool can be detachably connected;
- a first movable element that moves the first connection unit;
- a second movable element that moves the second connection unit;
- and
- a controller that controls driving of the first movable element and the second movable element, to execute machining of a workpiece by the sub-tool connected to the first connection unit and the second connection unit.
A tool to be detachably connected to a first movable element and a second movable element provided in a machine tool, the tool comprising:
- a first connected unit to be detachably connected to the first movable element;
- a second connected unit to be detachably connected to the second movable element;
- and
- a machining unit that contacts a workpiece and machines the workpiece.
A control program of a machine tool that executes machining of a workpiece by one sub-tool connected to a first movable element and a second movable element, the program, when executed, causing:
- a storage unit provided in the machine tool to store sub-tool data including a characteristic of the sub-tool;
- and
- a controller provided in the machine tool to interpret machining program data instructed by an operator, to calculate a movement trajectory of the sub-tool and to control movements of the first movable element and the second movable element based on the calculated movement trajectory and the sub-tool data.
