Aligning Tools on a Press by Means of 3D Scanning

The paper presents the way the 3D scanning was used to correct miss-alignment of the tools on a metal sheet bending press. Parts obtained by bending where not conform to requirements, and the reason was unknown. In order to find the error, the shape, size, and alignment of bending board and stamp had to be checked. The particular very long tools imposed as the single appropriate method of measurement: 3D scanning. The point clouds gathered by 3D scanning were processed to get the 3D models of the tools. Analyzing the models of the tools and their relative position led to conclusions that revealed the error and allowed fixing the problem.
