Abstract: A workpiece contour (13) at least first and second contour geometries (K1-K2) adjoining one another tangentially at a first transition point (U1). Measurement points (M) are recorded along the geometries (K1-K2). Using some measurement points within the first geometry (K1), a first replacement element (G1) is determined and assigned to the first geometry (K1). Analogously, using some measurement points (M) of the second geometry (K2) a second geometry element (G2) assigned to the latter is determined. The size and/or the position of the second geometry element (G2) are calculated under the boundary condition that the second replacement element (G2) adjoins the first replacement element (G1) tangentially. The tangential transition point between the two replacement elements (G1), (G2) forms the first transition point (U1). This method can be iterated using additional or other measurement points (M), until the first transition point (U1) is determined with sufficient accuracy.

Measurement points (M) are recorded along the geometries (K1-K2). Using some measurement points within the first geometry (K1), a first replacement element (01) is determined and assigned to the first geometry (K1). Analogously, using some measurement points (M) of the second geometry (K2) a second geometry element (G2) assigned to the latter is determined. The size and/or the position of the second geometry element (G2) are calculated under the boundary condition that the second replacement element (G2) adjoins the first replacement element (G1) tangentially.
