  • Patent number: 10500641
    Abstract: An additive manufacturing apparatus including a build chamber, build platform lowerable in the chamber so layers of flowable material can successively form across the platform, laser for generating a laser beam, scanning unit for directing the laser beam onto each layer to selectively solidify the material and a processor for controlling the scanning unit. The processor controls the scanning unit directs the laser beam to solidify a selected area of material by advancing the laser beam many times along a scan path. On each pass, the laser beam solidifies spaced apart sections of the scan path, each subsequent pass solidifying sections that are located between sections solidified on a previous pass. The processor controls the scanning unit to direct the laser beam to solidify selected area of material by solidifying sub-millimetre sized sections of non-continuously area and in an order such that consecutively solidified sections are spaced apart.

  • Patent number: 10401162
    Abstract: A machine tool is provided with a toolsetting probe mounted on a bed or table, and a workpiece-sensing probe which can be mounted in a movable spindle. Both probes are calibrated by using them to make measurements against each other. The arbitrary length of the workpiece-sensing probe is used to calibrate the toolsetting probe, rather than using a pre-calibrated artefact of known length mounted in the spindle. A stylus disc of the toolsetting probe has a pre-calibrated size or dimension, and the workpiece-sensing probe is calibrated with respect to that. This obviates the need for skilful manual calibration procedures using pre-calibrated artefacts and manual measurement tools.
