Abstract

In order to improve a method for positioning a centre point of a second machine tool unit of a machine tool on a geometric axis of a first machine tool unit of the machine tool, wherein the second machine tool unit has a circular path concentric with the centre point, and wherein the first machine tool unit has a component that is rotatable about the geometric axis, in such a way that said method can be performed by an operator easily, reliably and within a short timeframe, it is proposed that a measuring unit is arranged in a defined manner relative to the geometric axis and the position of the circular path relative to the geometric axis is established using the measuring unit, that the position of the centre point of the circular path in the geometric plane relative to the geometric axis is calculated, and that adjustment paths in the geometric plane, which are associated with the adjustment directions, for positioning the centre point on the geometric axis are calculated, and that the machine tool units are moved relative to one another in accordance with these adjustment paths.
