Paper Abstract

The optimization of re-production processes in the industrial manufacturing has long been the main interest in order to stay competitive. Only lately the idea spreads that optimizing the pro- duction, in the sense of innovation, could bring further improvement. This paper discusses aspects of introducing automation technology into the manufacturing of one-of-a-kind products. The co-ordination of 3D-optical feed-back with a graphic layout-, off-line programming and simulation system, and with a dual robot cell for flame-cutting, arc-welding and assembly is being developed at the BIBA as a demonstrator and testbed. The main emphasis is put on the active structured lighting for optical 3D-measurement with LCD-line projectors. The concept of the coded light approach and the phase shifting method for the 3D- data acquisition are described. With attention to the application in a robot cell for one-of-a- kind production the components of the measurement system are designed as robot based tools. For calibration and inspection purposes operation sequences are planned with the graphic simulation system. For the extraction of special points out of the 3D-clusters a simple and pragmatic method is applied.
