Abstract
In a method of machining a workpiece (60) having first and second gearings (61, 62), a reference tooth structure of the first gearing (61) is identified. The reference tooth structure is then measured with a reference measuring device (140) to determine a reference rotational angular position of the workpiece. Subsequently, the second gearing (62) is machined in such a way that the second gearing obtains a rotational angular position which is in a predetermined relationship to the determined reference rotational angular position.
Claims31
A method of machining a workpiece having first and second gearings, the workpiece being mounted for rotation about a workpiece axis, the method comprising:
- identifying at least one reference tooth structure of the first gearing with a reference identification device operating without contact;
- measuring the at least one reference tooth structure with a reference measuring device to determine a reference rotational angular position of the workpiece;
- and
- machining the second gearing with a machining tool in such a way that the second gearing obtains a rotational angular position that is in a predetermined relationship to the determined reference rotational angular position.
A positioning device for determining a reference rotational angular position of a workpiece having first and second gearings, the positioning device comprising:
- a reference identification device configured to identify at least one reference tooth structure of the first gearing without contact;
- and
- a reference measuring device configured to measure the reference tooth structure of the first gearing identified by the reference identification device to determine the reference rotational angular position of the workpiece.
A machine tool, comprising:
- a workpiece carrier;
- at least one workpiece spindle arranged on the workpiece carrier and configured to receive a workpiece having first and second gearings for rotation about a workpiece axis;
- and
- a positioning device for determining a reference rotational angular position of the workpiece, the positioning device comprising a reference identification device configured to identify at least one reference tooth structure of the first gearing without contact, and a reference measuring device configured to measure the reference tooth structure of the first gearing identified by the reference identification device to determine the reference rotational angular position of the workpiece.
