The disclosure provides a technical solution for determining centers and the spatial course of the centers of a hollow shaft rotatably clamped as a workpiece in a machine tool, which is machined on its outer surface at least in sections. The disclosure provides a technical solution in this respect using methods other than ultrasound. This aim is solved by using a sensor operating according to the eddy current principle, whereby process-engineering and device-engineering features are described in more detail.

A pure-rolling generating measurement method and device for gear helix artifact is proposed, which use a dividing table to accurately control the linear rail slide block assembly component to rotate according to the helix angle of different base circle. The height of the measuring point is the installation height of the working plane of generating rails, so as to ensure that the measuring point is always located on the dividing cylindrical surface of the gear helix artifact. When the gear helix artifact does pure-rolling motion, the slide block performs high-precision linear motion on the working surface of two fixed rails; the pure-rolling motion is proportional to the high-precision linear motion, so that the inductor micro-displacement probe can complete the measurement of the helix deviations of the gear helix artifact with different base circle helix angle.

A sensor device for measuring a rotational position of an element that is rotatable about an axis of rotation includes a sender member emitting a magnetic field and a plurality of receiving members receiving the magnetic field. Each of the receiving members has a pair of conductors that together delimit a pair of surrounded areas. Each of the surrounded areas tapers in and against a circumferential direction at ends of the surrounded areas.

A tool for detecting a covered edge of a structural member through sealant material of a fillet seal includes an edge detection probe mounted to a fixture. The probe outputs an interrogation signal toward the covered edge and receives a return signal indicative of a location of the covered edge. The tool includes an electronic control unit (“ECU”) in communication with the edge detection probe and a display screen. The ECU is configured to generate, from the return signal, one or more XY coordinates indicative of the edge location, and to display the edge location on the display screen. Additionally, the tool includes a seal measurement device. In response to the edge location, the device measures a predetermined dimension of the fillet seal, including a thickness and/or a shape of the fillet seal. A method includes detecting the covered edge using the tool.
