Abstract
A method having the steps of measuring a geometry of a toothing using an optical measuring system, wherein a numerical aperture of the optical measuring system is adjustable and the numerical aperture of the optical measuring system is adapted depending on at least one geometric parameter of the toothing to be measured and/or is enlarged or reduced.
Claims9
A method including the following steps:
- measuring a geometry of a toothing using an optical measuring system, wherein a numerical aperture of the optical measuring system is adjustable and is adapted, increased, or decreased, wherein the optical measuring system generates illumination beams,
- depending on at least one geometric parameter of the toothing to be measured, wherein at least one of the following requirements are fulfilled to adapt, increase or decrease the numerical aperture to the toothing to be measured:
- the geometric parameter is a tooth pitch or a gap width of the toothing,
- edge beams of the illumination beams of the optical measuring system are not shadowed by a tooth of the toothing,
- the numerical aperture is determined by calculation, on the basis of a predetermined nominal geometry of the toothing and a predetermined measuring angle.
