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

摘要

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 (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. 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.

1. A method for measuring the contour of a workpiece (14) comprising a first contour geometry (K1) and a second contour geometry (K2) and a first transition point (U1), at which the first and the second contour geometry (K1, K2) adjoin one another, wherein the connection at the first transition point (U1) is to run tangentially, the method comprising:
(a) measuring a plurality of measurement points (M) along the first contour geometry (K1) and the second contour geometry (K2), (b) determining a first replacement element (G1) for the first contour geometry (K1) using at least one measurement point (M) in the area of the first contour geometry (K1), (c) determining a second replacement element (G2) for the second contour geometry (K2) using of at least one measurement point (M) in the area of the second contour geometry (K2), (d) calculating the position and/or the size of the first replacement element (G1) and/or of the second replacement element (G2) under the boundary condition that the first replacement element (G1) and the second replacement element (G2) adjoin one another tangentially, (e) determining the position of the first transition point (U1) at the location, at which the first replacement element (G1) and the second replacement element (G2) adjoin one another tangentially.
