Contact measurement on the tooth flank of a gearwheel workpiece

A measuring apparatus comprising:

• at least one probe configured and adapted for contact measurement on at least one tooth flank of a gearwheel workpiece;
• and
• a controller configured to implement the following steps:
• defining a maximum region relating to a tooth flank of a gearwheel workpiece,
• defining a critical region relating to the tooth flank, wherein the critical region at least partly overlaps the maximum region,
• executing relative movements of the probe to guide the probe along the tooth flank and
• obtaining actual measured values of the tooth flank with a first resolution at a plurality of locations within the maximum region, and
• obtaining actual measured values of the tooth flank with a second resolution at a plurality of locations within the critical region, wherein the second resolution is higher than the first resolution.
