  • Patent number: 8114000
    Abstract: A tool changing unit moves between a magazine position and a changing position to transfer a tool. A machine tool has a plurality of tool changing positions. One of the tool changing positions is selected in advance for changing the tools next time. The tool changing unit and the tool mounted on a tool spindle move to the selected changing position for changing the tools in the selected changing position. Accordingly, the tool changing unit and the tool spindle move respective short distances for changing the tools, thereby shortening the non-machining time of a machine tool combined with the automatic tool changer.

  • Patent number: 5274562
    Abstract: A "safe" position for a tool changing operation in a numerically controlled machine tool is determined based on specific tool size and machining location. In one embodiment, tool change positions are taught in a teaching operation, and are stored for future reference. During machining, as each tool changing position is encountered, a pointer has advanced to the next such position so that, upon execution of the next tool changing command, the unit moves to the appropriate location. According to other embodiments, the machining program itself is made to store the tool changing positions. This data may be added to the program by an editor on the basis of the information found in the memory, or the data may be added in the initial creation of the program. The data on tool changing positions is then decoded from the machining program when the program is read or executed.

  • Patent number: 5244447
    Abstract: A tool management method in a factory automation (FA) system uses an FA computer and machining cells. An FA computer such as a cell controller is connected with computer numerically-controlled units via bi-directional communication lines. When data on a tool service life or the like is changed on the cell controller (S1, S2), the changed data on the tool service life is sent to a computer numerically-controlled unit (S3) to update the data on the tool service life stored in the computer numerically-controlled unit (CNC) (S4). Similarly, when the computer numerically-controlled unit changes the number of times the tool has been used or the like, the changed data is sent to the cell controller in the same way. This enables the cell controller to be always informed of the most recent tool management data. And as the computer numerically-controlled units can immediately obtain tool management data that has been changed at the cell controller, a more efficient tool management is ensured.
