“…The highly reflecting aluminium surface may have a negative impact on image evaluation. The reflections may be reduced by using diffuse or polarizing light, for example [13]. If the profile surface is illuminated with polarizing light, the light reflected from the profile surface will also be polarized.…”

Abstract. This article describes a clamping concept for the flexible machining of spatially curved profiles developed at the wbk Institute of Production Science of the Universität Karlsruhe (TH). Simple geometrical considerations form the basis of the prototypically implemented clamping system design. The approach presented in this article allows for accuracy improvements regarding the positioning of the profile in the clamping system on the basis of markings applied onto the surface of the profile. Besides, the preliminary test rig set up and first results on the detection of the markings by means of digital image processing are presented.

A new thermographic online system for quality control in the laminating process is presented in this paper. The developed online system allows a 100% control of the laminating process of wood-based panels. Different types of invisible defects can be selected for detection. The system is implemented on a standard PC and tested in an industrial production process of particle boards with a transportation speed of about 50 m/min. A processing speed of 12 images/sec was reached and in the case of a detected fault an alarm message is sent to the operational personnel.

The article describes some important considerations for an industrial application for the thixoforging of steel alloys. Extensive experience in the forming of aluminium, brass and steel alloys was made with the automated thixoforging unit set-up at the Institute for Metal Forming Technology. After a brief description of the thixoforging unit, the cycle of automated thixoforging is explained. Beside the demands of reheating in an inert atmosphere, some aspects of process monitoring are described. In relation to this, the installed industrial vision system is presented. The requirements for batch production dies in automated units are focused upon. The results of the experimental forming of steel alloys with two different materials for the thixoforging dies are presented. A comparison of both alloys 1.2714 and CuCrZr is made.
