A combined system having a function for rapidly detecting and correcting a positional misalignment between a machine tool and a robot. The combined system includes: a machine tool having a table and a workpiece fixing jig integrally movable with the table; a robot system separated from the machine tool and having a robot configured to supply or take out a workpiece to or from the jig; a network for information transmission between the machine tool and the robot; an interference judging part which judges occurrence of interference, based on a disturbance value of each axis of the robot, when the workpiece is supplied to or taken out from the jig; and an interference avoiding part which, when it is judged that the interference occurs, stops a motion of the robot and moves the table in a direction of at least one axis based on the disturbance value.

A machine tool system and an opening stop position calculating device are provided. The machine tool system includes an openable and closable door for closing an opening of a cover surrounding a machine tool. Furthermore, the machine tool system includes an opening width setting unit for setting an opening width of the door, an opening stop position calculating unit for calculating an opening stop position of the door at which a total time, which is obtained by summing a time required to move the door from a fully closed position to a position of the set opening width and a time required to move the door from an opening stop position where the door is opened and stopped to the fully closed position, is minimized, and a door control unit for controlling opening and closing of the door based on the calculated opening stop position when exchanging the workpiece.

A coordinate measuring machine includes a body, a controller configured to control the driving of the body, and an operation unit configured to provide a command to the controller via, for instance, an operation lever to manually operate the body. A contact detection sensor is attached to the operation unit. The controller includes a sensor signal determiner configured to detect an operation-enable signal in response to a detection signal from the contact detection sensor.

A device management apparatus includes a board working machine and a management section. The board working machine includes a first slot and a second slot, and performs a predetermined board work on a board to produce a board product. The first slot can hold a device used in the production of the board product. The second slot can preliminarily hold the device that is scheduled to be used in the production of the board product or can temporarily hold the device that has become unnecessary in the production of the board product. The management section updates a control program for controlling the device of a target device requiring update of the control program in the second slot.
