Method of measuring and testing a workpiece and gear cutting machine

A method for measuring and testing a workpiece belonging to a gear pair, wherein the method is carried out on a gear cutting machine producing the workpiece and the gear pair is either a worm gear or a cylindrical gear pair, comprising the method steps of:

• a. moving a mating test piece mounted at a working head, in a direction of the workpiece clamped in a workpiece mount of a machine table, and/or moving the workpiece mount in the direction of the working head, until the gear pair is in engagement and/or until the corresponding working axial spacing is reached;
• b. driving the workpiece about its workpiece rotational axis via rotational drive movement of the mating test piece of the gear pair;
• c. recording rotational position of a workpiece to be measured;
• and
• d. comparing a detected actual position with a reference position and calculating at least one value characterizing a rolling gear deviation while taking account of the comparison made.
