A metrological apparatus (15) is disposed for adjustment of an attitude of a workpiece (16) having an arcuate upper surface (17) relative to a rotary axis (C) of the metrological apparatus (15). The workpiece (16) is brought into a first rotary position (c1). A plurality of measured points within a measuring plane on the upper surface (17) is recorded. The workpiece (16) is moved into a further rotary position (c2) about the rotary axis (C), and again measured points in the measuring plane (E) on the upper surface (17) of the workpiece (16) are recorded. Based on these recorded measured points, the actual attitude (Li) of the workpiece (16) deviation from a specified target attitude (Ls) are determined. Adjustment parameters are determined, and an adjustment assembly (24) of the metrological apparatus (15) is activated as a function of the calculated adjustment parameters to adjust the workpiece (16).

A lapping device for gear helix artifact with equal common normal by rolling method, use the rotary table to accurately control the angle between the lapping surface of whetstone and the axis of the base-circle cylinder to control the helix angle of base-circle about the involute helicoid. Use the whetstone driven component to drive the whetstone to make a high-precision linear motion in the vertical direction to adjust the position of the lapping surface of whetstone. The distance between the two lapping surface of whetstone is precisely adjusted by the gauge block to control the processing length of the three tooth common normal of the gear helix artifact. The invention provides a lapping device for gear helix artifact with equal common normal by rolling method, it conforms to the generation principle of the involute helicoid, and there is no machining principle error.

This invention relates to a container wall thickness inspection device 1 for inspecting a container 10A in which regions with a relatively greater wall thickness (flat portion Rf) and regions with a relatively smaller wall thickness (corner portion Rc) are distributed in the circumferential direction, the container wall thickness inspection device 1 comprising: a wall thickness measurement device (electrostatic capacity detector 4) with a sensor unit 5 for measuring a wall thickness of a site facing the sensor unit 5 on the outer peripheral surface of the container 10A; a rotary drive mechanism for axially rotating the container 10A around the central axis of the container in order to measure a wall thickness of the container over the entire circumference by the wall thickness measurement device; a region detection device (photoelectric sensor 8) for detecting which region of the container 10A corresponds to the site being measured for its wall thickness by the wall thickness measurement device; and a determination device for making a pass/fail determination with respect to the wall thickness of the container 10A based on measured wall thickness values over the entire circumference of the container 10a, which are obtained from outputs of the wall thickness measurement device. The determination device comprises a storage unit for storing a pass/fail determination standard value with respect to the wall thickness for each region, and a comparison unit for comparing each measured wall thickness value obtained from the outputs of the wall thickness measurement device with a pass/fail determination standard value stored in the storage unit corresponding to the region detected by the region detection device.

A probe assembly for measuring a synthetic turf infill profile having a probe, a turf surface contact assembly and a sensor. The probe is configured to extend down through the turf infill profile until a tip of the probe contacts a lower boundary of the turf infill profile. The surface contact assembly is vertically movable relative to the probe while the probe is being moved downwardly into the turf infill profile, wherein the surface contact assembly has a contact area with the turf surface that is large enough to retain the surface contact assembly resting atop an upper boundary of the turf infill profile when the lowermost tip of the at least one probe has contacted the lower boundary of the turf infill profile. The sensor reads the distance between the upper and lower boundaries of the turf infill profile at a sampled location in the turf surface.
