Abstract
A method for the location determination of the involutes of a pre-gear cut workpiece within a gear-cutting machine using a gear-cut tool comprising the method steps: generating first and second relative movements between the workpiece and the tool; detecting respective, resulting first and second contact between a first tooth flank of the tool and a first tooth flank of the workpiece; and detecting a respective first and second set of coordinates for representing the relative movement of the workpiece and the tool; and determining the angles of rotation, the feeds, the axial distance and the crossed-axes angle of the tool and the workpiece based on the first and second set of coordinates and subsequent calculation of the location of the involutes on the basis of the angles of rotation, the feeds, the axial distance and the crossed-axes angle.
