  • Patent number: 9726481
    Abstract: A method of building up a measurement data set for a surface of an object using an analog measurement probe mounted on a machine tool apparatus which obtains scanned measurement data of the surface over a plurality of offset traverses. Subsequent traverses are offset from previous traverses such that over a series of traverses the analog probe's surface detecting region progresses i) laterally across the object, and/or ii) away from or towards the object. The course of relative motion for at least one subsequent traverse is generated and/or updated based on data obtained during at least one previous traverse.

  • Publication number: 20160306901
    Abstract: A method and apparatus for generating geometric data are to be used in the building of an object using a layer-by-layer additive manufacturing process. The method includes providing object data defining the object, identifying from the object data one or more regions of a surface of the object to be supported during the additive manufacturing process and, for the or each region, identifying one or more supporting structures that will provide support for the region and generating an arrangement of supports within the region. A support location of each support of the arrangement relative to the other supports of the arrangement is derived from a location of the supporting structures.

  • Publication number: 20120041740
    Abstract: The surface of a dental part is scanned by a probe, to obtain a digital model of the surface in a dental CAD computer system. In the digital model, first and second boundary lines are defined, above and below a portion in which the scanned data is missing or unsatisfactory. One of the boundary lines may correspond to a margin line between prepared and unprepared portions of the patient's tooth. A transition surface is generated in the computer system, extending between the first and second boundary lines. This improves the representation of the dental part in the digital model, which may subsequently be used for manufacture of a dental restoration.
