A precision machine tool includes: a tool support for supporting a tool; a tool table serving as a moving mechanism capable of moving the tool support; and one or multiple imaging devices fixed to the tool support, the imaging devices each having an imaging unit configured to capture the image of a machining point on a workpiece machined by the tool.

When measuring the position of a workpiece fixed to a table of a machine tool: rotary feed axes of the machine tool are pivoted such that an upper surface of the table faces in the direction of a line of sight of a camera, and an image of the workpiece is captured; the rotary feed axes are pivoted such that a side surface of the table faces in the direction of the line of sight of an image capturing device, and an image of the workpiece is captured; and the position of the workpiece is measured on the machine tool on the basis of the captured images.

A motorized apparatus for use in maintaining a turbine assembly includes a body configured to move through the turbine assembly. The motorized apparatus also includes at least one maintenance device coupled to the body. The motorized apparatus further includes a drive system configured to move the body relative to the turbine assembly. The drive system includes a motor and a steering component. The steering component is configured to steer the motorized apparatus relative to the turbine assembly.

A method for operating a motion-measuring system of a machine, such as a coordinate-measuring device or a machine tool. An image-recording device arranged on a first part of the machine records at least one recorded image of a second part of the machine. The first part and the second part can be moved in relation to each other. A capturing structure, which is formed by the second part and/or which is arranged on the second part, is captured by the at least one recorded image, and, by using information about an actual appearance of the capturing structure, a speed of the relative motion of the first part and the second part is determined from differences of the at least one recorded image from the actual appearance of the capturing structure.

Methods, sensors, and machines for transmitting machine access data of a machine to a wireless measurement sensor attached to the machine. A method of transmitting access data of a communication interface of a machine to a wireless measurement sensor attached to the machine includes: controlling a machine component of the machine which influences the measurement signals of the measurement sensor, according to specific information associated with the access data and evaluating the measurement signals to determine the access data of the communication interface of the machine.

A machine tool is provided which can execute various works while suppressing increase in cost or size. The machine tool includes a tool spindle device which is a movable member which can move with respect to a mounting surface of the machine tool, and one or more serial-manipulator-type robots attached on the tool spindle device, which can move with the tool spindle device, and which have two or more degrees of freedom, and the robot includes two or more end effectors provided at positions different from each other with one or more joints therebetween.

An image capturing apparatus includes: a coordinate value acquisition unit that acquires first coordinate values serving as position information of a moving target; an image capturing unit that captures an image of the target; a direction and distance calculation unit that calculates a direction of an optical axis that connects the target and the image capturing unit and a distance between the target and the image capturing unit on the optical axis on the basis of the first coordinate values and second coordinate values serving as position information of the image capturing unit; an attitude control unit that controls an attitude of the image capturing unit on the basis of the calculated direction of the optical axis; and an imaging magnification setting unit that sets an imaging magnification of the target in the image capturing unit on the basis of the calculated distance, wherein the image of the moving target is captured while changing the imaging magnification of the target and the attitude of the image capturing unit.

Multiple cameras are used for tool positioning, as-built documentation, and/or personnel monitoring in construction site. A camera unit comprises one or more imaging devices, a processing computer, and a communication device. The camera units are placed at multiple locations in a construction site to cover an area. The camera units are self-positioned by detecting a calibration target that moves within a working volume. The camera units can detect and calculate positions of objects, including measurement sticks, tools, personnel, etc., in the area.

The machine tool includes a tool post linearly movable along a direction parallel to an X axis and a direction parallel to a Z axis, a workpiece spindle which retains a workpiece in a condition rotatable about an axis parallel to the Z axis, and an in-machine robot which is installed in a machining chamber and has joints. The joints of the in-machine robot include a base joint rotatable about an axis parallel to the Z axis, and three parallel joints rotatable about an axis orthogonal to the axis of rotation of the base joint, the parallel joints being located on a distal end side of the base joint and successively arranged from the base joint. The axis of rotation of the base joint is displaced from that of the workpiece spindle.

A machine tool is disclosed which continues monitoring even when there is an obstacle such as swarf or a cutting fluid between a machining portion to be monitored and a visual sensor. A visual sensor is attached to an in-machine robot which is movable in a machine tool. A controller operates the visual sensor while judging influences of the swarf and the cutting fluid, automatically judges an orientation experiencing less influence, and executes monitoring from an optimum direction.
