A three-dimensional measurement device includes a camera for acquiring position information for three-dimensional points on the surface of an object on the basis of the time of flight of light, and a control device. The camera acquires, at a plurality of relative positions of the camera with respect to a workpiece, three-dimensional point position information. A plurality of evaluation regions are defined for the workpiece. The control device specifies, for each evaluation region, the three-dimensional point closest to a reference plane from among three-dimensional points detected in the evaluation region. The control device generates, on the basis of the multiple three-dimensional points specified for the respective evaluation regions, three-dimensional point position information in which multiple pieces of three-dimensional point position information acquired by the camera are combined.

A method for carrying out a robot-assisted measurement of measurable objects. The paths of a sensor are defined and transmitted to a robot co-ordinate system. The actual paths of the sensor guided on the robot are recorded. A plurality of measurable objects is measured, the sensor being guided with the robot along the actual paths. A compensating device makes it possible to compensate internal and/or external influences produced on the robot. The compensation stage is carried out after a determined number of measurements.

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.

A system and method for using a probe assembly to apply a desired force to a target surface. The method includes moving the probe assembly into an approach position, the approach position being a predetermined distance from the target surface. The probe assembly is then moved from the approach position to the target surface pursuant to a soft landing procedure. The soft landing procedure includes determining that the probe assembly has moved into soft contact with the target surface. The method further includes applying, subsequent to establishment of the soft contact between the probe assembly and the target surface, force to the probe assembly until an applied force on the target surface reaches the desired force. The applied force may then be monitored based upon an output of a load cell responsive to a force exerted by the probe assembly.

A coordinate measuring machine based on a delta robot structure comprising a base plate, arms, a movable platform with a probe, and a control unit for controlling the movement of the movable platform. The base plate is configured to accommodate a first workpiece and the probe is arranged the movable platform so as to utilize the free inside space of the delta robot structure between the arms as measuring volume.

A system to control a workpiece during its manufacturing in a machining system. The control being performed in the same manufacturing phase following machining operation. The workpiece being set in the work volume of the machining system. The check operation includes the acquisition of points on the surface of the part. The robot is moved by a cart so the robot can reach the protected working area. The measuring device is positioned relative to the workpiece by the robot. Acquisition of a plurality of points on the surface of the workpiece is performed. The position of the plurality points acquired is compared with the three-dimensional model stored in the memory of the computer.

A device for automatically detecting a through-hole rate of a honeycomb sandwich composite-based acoustic liner, including a customized tooling, a data acquisition system, a motion mechanism and a data processing system. The data acquisition system is configured to acquire a surface three-dimensional (3D) point cloud data of an acoustic liner using a two-dimensional (2D) laser profile sensor in a manner of parallel movement shooting, and connected with a graphics workstation. The motion mechanism includes an industrial robot, and the 2D laser profile sensor is fixed at an end of the industrial robot. The motion mechanism is configured to support the data acquisition system to perform translational scanning. The data processing system includes the graphics workstation, and plays a role of path planning and data storage. A method for automatically detecting a through-hole rate of a honeycomb sandwich composite-based acoustic liner is also provided.

A bore metrology method includes aligning a first structure, which defines an initial bore, with a second structure, which defines a pilot bore, such that the initial bore is partially obstructed by the second structure and the pilot bore is superimposed with the initial bore. The initial bore includes a bore locating target assembly within the initial bore, the bore locating target assembly having an optical target, the optical target having a reflector and an optical absorbing feature, the optical absorbing feature defining a pattern on the optical target. At least a portion of the reflector and at least a portion of the pattern are visible through the pilot bore. The method further includes imaging the portion of the reflector and the portion of the pattern that are visible through the pilot bore. The method further includes determining a centerline of the initial bore based on the imaging.

A control device adapted to control a robot including a robot arm provided with a force detector includes a processor that is configured to execute computer-executable instructions so as to control the robot, wherein the processor is configured to: operate the robot arm to move a screw gauge which is disposed on a tip side of the force detector of the robot arm, used for an inspection of a screw hole, and provided with an external thread, to make the external thread have contact with the screw hole; then detect force applied to the screw gauge using the force detector to perform force control in a direction perpendicular to a direction of an axis of the screw hole based on detection information of the force detector; and operate the robot arm to move the screw gauge based on the force control.
