The paper presents arguments for and proposals of changes in the series of standards ISO 15530. In particular, authors propose to change the classification of themethods of uncertainty evaluation, change the title of the ISO 15530-4 and make changes that will facilitate the use of these standards to industrial employees. In authors’ opinion the classification of the uncertainty evaluation methods for coordinate measurements should be based on the models given in ISO 14253-2 and GUM, i.e. the terms of “black box” and “transparent box” as well as type A and B methods. Authors think that both...

The paper presents an idea of a new measuring method based on image tomography. This method insists in registration of images of the moving bubbles from two perpendicular directions. Two images are used for determination of the center of mass, movement trajectory and local velocities. Volume and area of the bubble are defined by approximation of the bubble shapes by the known geometric figures. The paper also presents the algorithm of reconstruction of the bubble shapes and movement trajectories, as well as exemplary test results. The obtained results were compared with theoretical...

This paper deals with implementation of requirements of standard ISO 9001. Quality management systems in accordance with requirements of standard ISO 9001 are implemented and accepted in broad number of companies in Croatia. First organizations that implemented these requirements were production companies from industry. Authors investigate differences at implementing requirements of standard ISO 9001 at organizations dealing with different kind of production companies. Using statistical tests, requirements of quality management system are determined, which have significant number of...

The article presents the authors’ method for monitoring the Friction Stir Welding (FSW) processes with use of thermal imaging camera. The FSW method is a modern and still not very common method for joining materials by mixing them after plasticizing with a special tool and allows the combination of non-welding and difficult to weld materials, including combining different (dissimilar) materials. FSW method is a new method and there still are few tools to assess the quality of the process, especially on-line, that is in the making of the weld. The authors propose a new method for on-line...

Nanoindentation testing has proven to be effective for the determination of the mechanical properties of small structures. Accurate material measurements demand that nanoindentation instruments, especially their depth sensing system, be carefully calibrated. Here a homodyne laser interferometer is realized for insitu investigation of the displacement measuring performance of a commercial nanoindentation instrument. By means of real-time inspection of the axial movement of a spherical indenter mounted on the transducer of the nanoindentation instrument, the developed laser interferometer is...

Choosing the right laser tracker system for large-scale metrology is not easy. Currently on the market there are several manufacturers of laser tracker systems, such as: Leica, Faro, API and Nikon. What is new is the Etalon LaserTracer. They differ in terms of construction, application and also the accuracy of the system. What is more there is no one common international standard for the evaluation of their accuracy. The international standard is currently under preparation. So the accuracy of laser tracker systems are provided in a many different way by manufacturers. Therefore, there is a...

Quality engineering is an interdisciplinary science which is concerned with not only producing satisfactory products for customers but also reducing the total loss. Quality engineering involves engineering design, process operations, after-sales services, economics and statistics. Although the Taguchi Robust Design is the first concept comes to mind when thinking of quality engineering, the definition of this major has been used in different manners in the literature. There are also differences on the definition of the quality which has been made by experts. The aim of this study is to...

The measurements were performed on the surfaces made of different materials and typical of diversified character. Glass roughness standards with sinusoidal profile, approximately sinusoidal profile and metallic comparative standards after lathing and grinding were object ofresearch. Analysis was performed including the surface and profile evaluation. Statistical analysis was conducted. Measurement sections and other filter parameters were selected in accordance with standards. Measurements were carried out with stylus tip contact method – using TOPO 01P device designed by The Institute of...

Besides dimensional and shape accuracy, eliability and life cycle of components produced in different wayshighly depend on the quality of the processed surface. There are some automotive industrial parts where it is important to have appropriate surfaces. In these cases it is necessary to examine the measurement process for its suitability, for its capability. The calculation methods of capability of measurement processes in automotive industry differ from each other. There are three main calculation methods: MSA, VDA 5 and the international standard, ISO 22514-7. During this research our...
