Classification: CPC G  B | IPC B  G

Claim 0:
1. A positioning method for automatically positioning a tool of a machine tool device relative to a workpiece and a component, wherein the machine tool device comprises a measuring device and a controller, wherein the positioning method comprises the steps of:
1.1 providing a component having a joining portion, wherein the joining portion is manufactured to a final dimension and is configured for joining the component to the workpiece, wherein the component has associated with it at least one first measured geometric datum indicative of a manufactured geometric property of the joining portion, wherein the first measured geometric datum is stored in machine readable form in a data storage;
1.2 positioning the component relative to the workpiece in a predetermined position based on the first measured geometric datum;
1.3 with the measuring device, measuring the joining portion after the component was arranged at the predetermined position to obtain at least one second measured geometric datum that corresponds to the respective first measured geometric datum stored in the data storage;
1.4 with the controller, retrieving the first measured geometric datum from the data storage and determining a deviation between the retrieved first measured geometric datum and the second measured geometric datum; and
1.5 with the controller, controlling the machine tool device such that the tool is moved to a predetermined working position, if the deviation is determined to be below a predetermined threshold,
wherein the data storage is a machine readable tag attached to the component,
the method further comprising the step of scanning the machine readable tag to retrieve the first measured geometric datum.
