CONTOUR METER AND METHOD FOR MEASURING THE CONTOUR OF A WORKPIECE HAVING TANGENTIALLY ADJOINING CONTOUR GEOMETRIES

摘要

The invention relates to a contour meter (10) and also to a method for measuring a workpiece contour (13). The workpiece contour (13) has a plurality of contour geometries (k). At least a first contour geometry (K1) and a second contour geometry (K2) adjoin one another tangentially at a first transition point (U1). Firstly, a multiplicity of measurement points (M) are recorded along the first contour geometry (K1) and the second contour geometry (K2). On the basis of some of the measurement points within the first contour geometry (K1), a first replacement element (G1) is determined and assigned to the first contour geometry (K1). Analogously to this, on the basis of some measurement points (M) of the second contour 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 here 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 thus determined first transition point (U1). This method can be repeated iteratively with the aid of additional or other measurement points (M), until the position of the first transition point (U1) has been determined with sufficient accuracy.
