EBSD – orientation analysis of monocrystalline diamonds used for diamond metal composites – Influence of sample preparation

This paper focuses on a new field of application for the EBSD‐technique. Generally, EBSD‐mappings are performed on different metal alloys used for quality assurance and to get information about the microstructure regarding grain orientation, grain size and distribution. In contrast, the orientation determination of monocrystalline diamond grains with an EBSD system is not a conventional method. Thus, this work describes the EBSD testing sequence in detail and illustrates the preparation of orientation data for a statistical design. Furthermore, dependencies of the sample preparation, alignment to the detector, and the analyzed position on the diamond on the quality of the Kikuchi‐patterns, respectively on the indexing rates, have been scrutinized. Finally, the orientation obtained of each tested diamond sample has been utilized in a statistical design to show a direct influence of the crystal orientation on the wear behavior of the diamond grains.     

The impact of quality management orientation on maintenance performance

This paper aims to examine the relationship between quality management orientation dimensions and maintenance performance. The concept of quality management orientation is proposed and defined as a set of norms and values regarding customer orientation, quality responsibility, prevention and process orientation. Empirical data were drawn from a sample of Slovenian organisations in order to address the research question. The data were analysed using exploratory factor analysis, confirmatory factor analysis, correlation analysis and regression analysis. The findings indicate that quality management orientation is important predictor of maintenance performance. Data analysis results also show that quality management orientation dimensions are positively related to maintenance performance. By testing the impact of quality management orientation on maintenance performance, this study shows that strong foundation on quality management orientation is an effective way of improving maintenance performance.     

An Objective-Oriented Rating System of Vendor Quality Performance

This article establishes a rating system for vendor's performance from the orientation of customer satisfaction by objective-orientation driving. Its purpose is to provide a methodology of “how to integrate the capability between vendor and manufacturer and to apply different strategies under the needs of quality improvement.”

The study is undertaken to specify the interaction and the mutual movement among the three groups in the supply chain “Vendor-Manufacturer-Customer” and to integrate the results of four factors: incoming inspection, performance of line reject, service quality of vendor, and product reliability. It tries to transform these factors into measurable, quantitative, just-in-time (JIT) parameters that are utilized in the planning and establishment of this rating system of vendor's performance. The concept of objective orientation is adopted in the “performance” calculations.

We obtain a very satisfactory completeness, flexibility, effectiveness, and sensitivity of parameters-to-model from the results of simulation and demonstration. The multi-parameters rating system of this study can be very beneficial to manufacturers in selecting the best vendor and in driving quality improvements.

Effect of governing metal thickness and stack orientation on weld quality and mechanical behaviour of resistance spot welding of AA5754 aluminium

A study was carried out to investigate the effect of governing metal thickness (GMT) and stack orientation on weld quality and mechanical behaviour of resistance spot welded (RSW) AA5754 aluminium. Individual samples from 27 different joint stacks in three test geometries; lap-shear, coach-peel and cross-tension were evaluated for quasi-static and fatigue performance; micro examination was also conducted on some of the samples to assess weld quality. The results derived from over 1000 samples show that: the GMT has a significant effect on welding quality by controlling progression of weld nugget from under-developed to over penetrated. The GMT also determines the feasible quasi-static joint strength regardless of stacks in the three joint geometries tested, though the effect differs with respect to test geometry. The fatigue behaviour is dominated by the effect of GMT on attainable weld size, overall joint stiffness and stress concentration, providing good quality of weld nuggets is achieved. No notable effect of stack orientation on weld quality and joint strength was found with respect to the joint stack asymmetry and welding orientation to the electrodes. These fundamental relationships between weld qualities, joint strength, GMT and stack orientation for RSW of aluminium will have significant relevance to design and manufacturing communities.
