    Abstract: A method of operating a machine tool apparatus, including: causing a tool mounted on the machine tool apparatus to work on a workpiece, during the working of the workpiece by the tool, at least one sensor monitoring the tool, machine tool apparatus and/or workpiece, for one or more signals indicative of the condition of the tool; and using the output of the one or more sensors to automatically configure when and/or how the tool and/or workpiece is inspected by at least one inspection device, the output of which is used to determine whether or not to keep using the tool.

    IPC: G01D5/347

    Abstract: A position measurement encoder including a scale and a readhead, the readhead including a sensor for sensing the scale, the sensor including a one-dimensional array of columnar pixels, configured such that the one-dimensional array of columnar pixels is divided into a plurality of rows wherein each columnar pixel has at least one individual sensing section in each row arranged to contribute to the columnar pixel's output. Each row is individually activatable so that which one or more of the individual sensing sections in the columnar pixels contribute to each columnar pixel's output can be selectively chosen and changed on a row-by-row basis.

    Abstract: A metrology apparatus including an articulated joint having: first and second bodies which can be locked together in a plurality of different angular orientations about a first axis; the first body including a prop which is actuatable by a motor between a retracted configuration at which the first and second bodies are in their locked state, and an extended configuration at which the first and second bodies are held apart by the prop along the first axis such that the first and second bodies are unlocked thereby permitting relative rotation of the first and second bodies, the prop and the second body being magnetically biased toward each other so as to magnetically retain the first and second bodies; and further including at least one supplemental bias member configured to bias the prop towards its retracted configuration.

    IPC: B23Q17/09

    CPC classification number: B23Q17/09

    Abstract: A hard-wired measurement device is mountable within an enclosure of a computer-controlled machine tool. The device includes a measurement sensor for measuring objects, such as tools, within the machine tool enclosure and a hard-wired interface module for providing an electrical connection via one or more wires with an associated external interface located outside of the machine tool enclosure. The device further includes a wireless communications module that enables wireless communication with an associated wireless device, such as a spindle probe, located within the machine tool enclosure.

    Abstract: A coordinate positioning arm includes: a base end and a head end; a drive frame for moving the head end relative to the base end; and a metrology frame for measuring a position and orientation of the head end relative to the base end. The drive frame includes a plurality of drive axes arranged in series between the base end and the head end. The metrology frame includes a plurality of metrology axes arranged in series between the base end and the head end. The metrology frame is adapted and arranged to be substantially separate and/or independent from the drive frame, for example by supporting the metrology frame substantially only at the base end and head end and by providing the metrology frame with sufficient degrees of freedom (via the metrology axes) to avoid creating an additional constraint between the metrology frame and the drive frame.

    CPC classification number: G01B5/012

    Abstract: A method of inspecting at least one feature of a part having a predetermined nominal shape, including: i) loading a contact probe onto a probe mount of a coordinate positioning apparatus which facilitates exchanging of probes thereon and relative movement of the mount and a part in three orthogonal degrees of freedom, the contact probe includes a reference member for engaging the part, and a stylus relative to the reference member and having a tip for contacting the surface to be measured; ii) bringing the reference member and stylus into contact with the part on one side of the feature, and then causing the stylus to traverse collecting measurement data concerning the relative position of tip and the reference member; and iii) extracting feature dimension information from the measurement data, and comparing the extracted dimension information to nominal dimension information for the nominal shape of the feature of the part.

    Abstract: In a workpiece production method a plurality of nominally similar workpieces are produced in a production process on one production machine. The order or time of production of some of the workpieces on the production machine is recorded. Some of the workpieces recorded are measured at two or more inspection stations. Dimensions or points of one workpiece are measured at one of the inspection stations, and corresponding dimensions or points of another of the workpieces are measured at another of the inspection stations. The results of the measurements of corresponding dimensions or points made at the two or more inspection stations are analysed together, taking account of the order or time of production of the workpieces. An output signal is produced based on the analysing of the results together. The output signal indicates performance of the production machine or of one or more of the inspection stations.
