Description
Entwicklung Lokal operierender Bearbeitungssysteme (LOBsys)
FKM 2001
Booklet No. 259
Project No. 231
When machining large workpieces, it is necessary to use correspondingly large machine tools to hold the workpiece in order to be able to machine it with the required accuracy. If a compact, locally operating machining system (LOBsys) uses a reference that has been approached once and then obtains its accuracy from the local coordinate system valid from the reference location, the effort and costs can be reduced. At the same time, the accuracy requirements are maintained. In an initial project phase, the application potential of locally operating processing systems was analyzed and evaluated. The result of these investigations was that this type of machine is a specialist. The sometimes very different demands placed on this type of machine require a wide variety of sensors and problem-optimized actuators. However, higher-level issues exist in the area of referencing, control and setup of these systems. As a result of these investigations, a sensor head was projected and constructed, which serves as an application example for such a system in aircraft assembly. In terms of positioning, the sensor head achieves a measuring accuracy of 50 IJm after calibration. In a second project phase, this type of machine was realized as a model. Finally, test runs with the sensor head were carried out on a machine for repairing large forming tools. The objective of the project was achieved. Scope of report:
