  • Publication number: 20200318683
    Abstract: The motion system for a CMM includes a measuring axis with an air bearing, a control unit for determining a position of the measuring probe in a reference frame and outputting the position as a measuring result. The first air bearing includes a guideway, slide having a slide surface and a gas outlet within the slide surface. The gas outlet is for providing a gas cushion in a gap between the slide surface and the guideway. A cover is arranged around the slide so a gap is provided between the cover and the guideway and a hollow space is provided between the cover and the slide. A wiper is arranged on the cover. A nozzle unit is supplied by a second gas supply line and for providing a high-pressure gas flow directed onto the guideway.

  • Publication number: 20200041311
    Abstract: A capacitive distance sensor for determining distances from an object, wherein the distance sensor has at least one sensor electrode and at least one compensation electrode. Deviations from an ideal parallel orientation of distance sensor and object and/or errors caused by capacitive edge effects can be compensated by means of the compensation electrode.
