Abstract:
This diploma thesis deals with the ¿Quality assurance in the industrial production for finger joint in structural use¿. Therefore, a quality handbook (Appendix A) was prepared, which can be used as a guideline for both quality managers and production personnel. It encloses the important process of plant certifications for five different markets (Europe, USA, Japan, Australia, and Germany), as well as a description of the associated production requirements, test instructions and the third party inspection control conditions. Furthermore, are listed; possible influences on the quality of finger jointed products, like production equipment, raw material, the climate in the production area, and their possibilities of improvements. Checklists and working sheets for quality managers and the production personnel complete the quality handbook. The scientific part of this paper deals with the statistical comparison of the finger joint quality. Therefore, two production sites (one in Central Europe and one in Northern Europe) were selected to take two testing rounds. The first testing round demonstrates the current state of the quality. Afterwards the quality handbook was implemented and after a short test phase the second test round was carried out. The second round demonstrates, whether there are significant differences on quality of the product by implementing the quality handbook. For appointing the quality a four-point bending test was carried out. The samples were tested flat and edgewise. The influence of adhesive bonding was done by the analysis of the type of fracture and the visual judgement of the fracture surfaces. Mill sites are not compared statistically, because of the big differences in plant characteristics, raw material, as well as the generated products.
