A machine tool includes a headstock for supporting a workpiece spindle to allow the workpiece spindle to rotate and a camera for imaging a tool held in a predetermined area. The camera is fixed to the headstock above the workpiece spindle with an optical axis of the camera inclined with respect to a vertical direction. The machine tool may further include an illumination unit arranged to face the camera. In this case, the area is formed between the camera and the illumination unit. The camera is arranged to be closer to the headstock than the illumination unit is.

A machine tool includes an imaging portion for imaging a tool in an imaging area, a tool holding unit capable of holding the tool in the imaging area, a shutter provided between a machining area and the imaging area, and being movable between an open state and a closed state, a cover for covering a light-receiving surface of the imaging portion, and a purge mechanism for performing purge by causing fluid to flow between a light-receiving surface of the imaging portion and the cover. (i) After the purge by the purge mechanism is performed, the machine tool (ii) moves the shutter, and (iii) moves the cover after start of moving of the shutter.

A system for image guided assembly of a structure, the structure defining an interior area accessible through at least one access opening, the interior area including at least one fastener hole. The system including a first fastening tool including an arm with first and second ends; and a support plate on the first end, the support plate including at least one connection member to securely retain a fastener therein, the at least one connection member configured to facilitate alignment of the fastener with the at least one fastener hole; an image capturing device disposed on the arm first end configured to generate a captured image of the interior area; a light source associated with the arm first end, the light source configured to generate light at the first end of the arm; and a display device located outside the interior area for displaying the captured image of the interior area.

A cleaning device includes: a lens cover configured to cover an object lens of a camera provided in a machining area of a machine tool, the lens cover being transparent; a motor configured to rotate the lens cover; and a wiping member configured to, when the lens cover rotates, wipe at least an adhering substance that has adhered to a region of the lens cover in an angle-of-view of the camera.

The present disclosure is directed to calibrating position detection for a tool. The tool can use a sensor to detect a first value of a parameter. The tool can use a motor to extend the working member of the tool towards a working surface. The tool can include a base. The tool can detect, with the working member in contact with the working service, a second value of the parameter. The tool can determine a z-axis position of the working member relative to the working surface.

The invention relates to a method for documenting at least one work step with a hand-held tool, wherein the hand-held tool has at least one camera mechanically connected to the tool, in which the steps of activating the camera and capturing images of the work step which is performed with the hand-held tool, and the generation of image data pertaining to the work step are provided.

A cable bushing fitting machine includes: a fitting region; a mandrel disposed at said fitting region, said mandrel being hollow to receive a cable therethrough; a first rotatably mounted stripping jaw arranged in the fitting region; a second rotatably mounted stripping jaw arranged in the fitting region; a drive configured to mount cable bushings onto cable by successively disposing respective ones of the cable bushings onto the mandrel, feeding the cable through the mandrel, and executing a relative movement between the mandrel and the first and second rotatably mounted stripping jaws to locate the respective cable bushings onto the cable; a camera directed toward the fitting region to capture images of the respective cable bushings located on the cable; and at least the first rotatably mounted stripping jaw having a rotation axis, the first stripping jaw rotation axis being laterally offset from an optical axis of said camera by a distance sufficient to permit the camera unimpeded views of cable bushings in the fitting region when the first stripping jaw is at least to a first selected extent opened.

A method includes determining an orientation and position of a moving polarization target based at least in part on a first image of the polarization target captured by a polarization camera and on a recorded polarization of the light that formed the first image.

A machine tool includes a cover body for separating at least a machining area from the outside. The cover body has an opening for allowing the machining area to communicate with the outside and includes a door for opening and closing the opening. The cover body does not include a transparent window for allowing the machining area to be visually checked from the outside. The cover body can be formed to be of a sufficient strength throughout and, if an unexpected accident occurs, structures within the machining area can be reliably prevented from being shot out of the machining area.

A mobile machine tool (10), namely a manually-operated machine tool (10) or semi-stationary machine tool (10), for machining a workpiece (W), wherein the machine tool (10) has a plate-like guide element (30) with a guide surface (32) for guiding the machine tool (10) on the workpiece (W) or the workpiece (W) on the machine tool (10), wherein the machine tool (10) has a drive unit (11) with a drive motor (13) for driving a tool holder (14) arranged on the drive unit (11) in order to hold a work tool (15), wherein the machine tool (10) has a tool sensor (61, 62), the detection range of which (EB1, EB2) is directed at at least a partial region of the machine tool (10), and wherein the machine tool (10) has an evaluation device (80) for evaluating a tool sensor signal generated by the tool sensor (61, 62). A reference marking (R1, R2) which can be detected by the tool sensor (61, 62) is arranged within the detection range (EB1, EB2) of the tool sensor and the evaluation device (80) is configured to determine at least one correction value for the tool sensor signal depending on the reference marking (R1, R2).
