  • Publication number: 20240353222
    Abstract: A method including the following steps of: providing a component, wherein the component has a gearing, wherein tooth flanks of the gearing have machining marks, determining at least one geometric feature of the machining marks, such as the height difference of the peaks and valleys, the flank-specific positions of the peaks and valleys, the offset or the like; carrying out an optical measurement of the gearing of the component, wherein a course of a measuring path for the optical measurement and/or wherein positions of measuring points for the optical measurement are defined taking into account the geometric feature of the machining marks and/or wherein an evaluation of measured values of the optical measurement is carried out taking into account the geometric feature of the machining marks.

  • Publication number: 20240151513
    Abstract: A coordinate measuring machine includes two or more linear axes, at least one rotational axis, an optical distance sensor for detecting measuring points on a workpiece to be measured, and a light source. The linear axes and rotational axis are adapted to carry out relative movements between the workpiece to be measured and the optical distance sensor. The light source is adapted to provide source light for the optical distance sensor and includes: an illuminant mounted on a carrier board and a material which emits broadband light under excitation, a laser for exciting the illuminant, a device for actively regulating the light intensity of the source light generated by the light source, a device for actively regulating a temperature within the light source, an optical system, and a light guide coupled to the optical distance sensor. The optical system is adapted to focus the source light into the light guide.

  • Publication number: 20220187060
    Abstract: A method includes the steps providing a component that has toothing with a predetermined nominal geometry; providing a measuring device that has an optical measuring system; and measuring the toothing of the component by the optical measuring system, wherein measuring points are detected. The method further includes the steps of evaluating the measuring points, wherein the evaluation of the measuring points has at least the following steps: grouping the measuring points into flank groups by filtering; modeling profile segments from the measuring points of the flank groups, wherein each flank group is assigned a profile segment; and determining one or more geometric parameters of the toothing on the basis of the profile segments.
