The technology of sheet-bulk metal forming enables the production of complex workpieces with filigree surface structures in only a few forming steps. In order to provide a rapid and production-related workpiece inspection of not only large workpiece features, but also small features in an appropriate quality, a multi-sensor optical measurement system with different resolutions is required. Workpiece features of medium size can be measured by two types of fringe projection sensors. With a structured approach according to Six Sigma, which is based on the five phases design, measure, analyze,...

In this study, an effective noncontact technique for the detection of human physical activity is proposed. We have develop a method for measuring human physical activity, which is based on detecting the electrostatic induction current generated by the walking motion under non-contact and non-attached conditions. A theoretical model for the electrostatic induction current generated because of a change in the electric potential of the human body is alsoproposed. By comparing the obtained electrostatic induction current with the theoretical model, it becomes obvious that this model effectively...

The article presents the results of the research conducted in Polish and French SMEs referring to the context of the implementation and application of the concept of Lean Six Sigma. The research was conducted in the form of case studies, observations and individual interviews. The pilot studies led to the identification of the needs, expectations, concerns and experience of these companies. At the same time possible benefits and the barriers related to the implementation of the Lean Six Sigma methodology in the SMEs were disclosed. The results of the research considered also the suggestions...

Thermal issues are relatively well developed and described in machine tools and their development is quite rapid in recent decades. This is related to increased awareness of the impact of thermal conditions on the accuracy and efficiency of their work and the increased requirements of users (up to 75% of the overall geometrical errors of machined workpieces can be induced by the effects of temperatures). There is a large stock of published research and case studies aimed at compensation and reduction of thermal error of machine tools. Branch of coordinate measuring machine (CMM) is strongly...

Measurement System Analysis (MSA) is a mandatory element of quality management systems in automotive industry. Suppliers has to comply both with ISO/TS 16949 and meet customer requirements specified in APQP (Advanced Product Quality Planning), PPAP (Production Part Approval Process) and MSA manuals. Manufacturing companies (not only in automotive industry) perform MSA studies for all measuring instruments specified in Control Plans. There are variety of methods available, with gauge R&R as the most popular, to conduct assessment of capability of a measuring system. However, although the...

The watt balance, a metrological instrument that might provide the new definition of the kilogram, consists of a moving coil which has a tight tolerance for its straight motion. Normal straightness sensors cannot be used for the watt balance because any electronic device might disturb the magnetic field around the coil. We propose a simple optical sensor to measure out-of-straightness of a moving coil. The sensor is comprised of a cube-corner prism and a reflector having a sharp edge. When a laser beam is incident on the cube-corner prism which is located on the moving coil, any...

Knowledge and understanding of modern machining processes often requires the use of advanced microscopy techniques, such as, among others confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). This work focused on the application of these microscopic techniques for measuring and analyzing of traces made by single abrasive grain cut, formed on the internal cylindrical surface of the sample made of INCOLOY ® alloy 800HT ® . The work was divided into two parts. In the first one, the most important types of materials machinability and grindability tests were briefly...

This work presents a concise review of selected issues related to non-contact optical metrology in applications where automated in-process inspection is involved. A brief description of the in-process inspection and applicable procedures were presented. A laser method based on analysis of scattered light was elaboratedin greater detail. In addition to the above, a short review of selected technical solutions in a form of an experimental and commercially manufactured measurement systems was presented. This review concentrates on describing of the most important metrological parameters,...

Laryngectomy is a medical operation, resulting in the loss of “normal” speech. Laryngectomees can learn to speak using their oesophagus; this takes intensive training, often in groups of about 5-10 patients and a trainer. It has become clear that in hospitals the requirements for rooms,meant for this type of rehabilitation are often not met. The aim of this research is to improve the acoustic functionality of the rooms for rehabilitation of laryngectomees. To this end, the acoustic parameters of such rooms have been measured: reverberation times, background levels, sound insulation of...

Measurement results represent important information, which are necessary for evaluating and improving the quality of manufactured products and to control manufacturing processes. Furthermore, they build the basis for numerous decisions in the field of quality management, process and production automation or product development and design. Knowledge about the acquisition, evaluation and interpretation of measurement data as well as an understanding of the relevant influences on those measurement results are essential for employees working in the field of manufacturing metrology. Measurement...
