Coordinate measurement instrument and method for its use in concentricity measurements, whereby stepper motors are provided to adjust the angle of inclination of a rotatable feeler head relative to its support axis
Coordinate measurement instrument and method for its use in concentricity measurements, whereby stepper motors are provided to adjust the angle of inclination of a rotatable feeler head relative to its support axis
Coordinate measurement instrument has a mandrel (16) in which a feeler head (21) is mounted so that it can rotate about an axis parallel to the mandrel's symmetry axis (17). Mandrel and feeler head are mounted on a carriage (2) that moves along a traverse (1). At least one device (11-13) is provided for direct or indirect alteration of the inclination of the rotation axis of the feeler head. An Independent claim is made for a method for measuring the concentricity of a measurement object (19) such as a drilled hole.
