Hybrid approach and sensor fusion for reliable condition monitoring of a mechatronic apparatus

In this paper the results are presented of a methodology for identification of the best setting of a mechatronic device at its set-up and/or of fault occurrence in working conditions. The condition monitoring approach merges the information deriving from experimental data of sensors and from a simulation model. The methodology is used to identify the most suitable quantities to be measured, independently on location for sensors. The hybrid information suggests a synthetic set of features, able to identify specific statuses of the mechatronic system, different as for initial setting and/or...

The long way to reliable inline production measurement in metal wire products manufacture

Optical inline measurement is common in textile production, but not in the manufacture of some metal wire products using comparable techniques. The reason is that some ISO standards require highly precise measurements which are hardly feasible in the running production. Major factors for getting results of the aperture - the most important value in this respect - are the time needed to focus the camera, strong vibrations of the weaving machines as well as the light on reflecting surfaces and reference objects. Even in offline measurement, the comparability of the results is limited due to...

Application of modern software engineering principles for continuous quality (CQ) management in research

Transparency of changes, automated testing of new developments against documented criteria, combination of developments from different sources and automated publication of validated results are key aspects of modern collaborative software engineering. Various infrastructures, guidelines and tools are available for continuous integration (CI) and continuous deployment (CD) of software. The same principles could be used to design infrastructures for continuous quality (CQ) management in research and the implementation of the Open Science paradigm. In this work we provide a vision of how such a...

Industry 4.0 in Germany, Austria and Hungary: interpretation, strategies and readiness models

Global economy increasingly responds to trends of industrial digitization and start to develop their own digitalization strategies e.i. through application of Industry 4.0 concepts. Thereby, initiatives and developments are often carried out on a company-, industry- or country-level, which can result in a lack of international co-operation and utilization of synergy-effects. To analyse the Industry 4.0 development status on a macro level and to enhance transnational developments, in the first part of this study we introduce the national Industry 4.0 platforms of three EU member states – the...

Review of Methodologies for the Assessment of the Technological Capability of RTOs

A New Perspective of the Cyber-Physical Production Planning System

The following three research fields and levels can be identified in the field of production planning and control (PPC): production planning, production scheduling and production control. These topics were thoroughly investigated from different points of view by several authors in the recent years. However, the connection and interaction of these fields in the era of cyber-physical production systems (CPPS) has not received so many attention from the research community. The objective of this conceptual paper is to overview the current status of these fields; to examine the possible connection...

The role of laboratories in the international development of accreditation

Laboratories are the larger group of stakeholders of ILAC, the international organization for accreditation. The impact of laboratory activities as independent entities that ensure safety and quality of products and services is growing and becoming a key issue in many fields. New challenges of globalization and international trade, technology developments and increasing expectations of citizens and consumers requires a robust implementation of accreditation to promote the fair competition and the sustainability of laboratories. For this purpose, harmonization and consistency of accreditation...

Experimental Investigation of Single Point Incremental Forming of Aluminium Alloy Foils

Incremental Sheet Forming is a prosperous process to manufacture sheet metal parts that is well adapted for prototypes or small batch production. Compared to traditional sheet forming technologies this relatively slow process is only profitable for the above mentioned production types but it can be used in different applications in automotive and aircraft industries, in architecture engineering and in medical aids manufacturing. In this paper indirectly obtained axial forming force on Single Point Incremental Forming (SPIF) of variable wall angle geometry were studied under different process...

Evaluation of material structure changing after ultrasonic milling of aluminium foam by Computed Tomography (CT )

In our everyday lives, we spend more and more time in our vehicles, where we are exposed to growing accident hazards. That is why we are increasingly focusing on security. This is particularly true for electric cars, where the size of the power source and the firewall are not the same as for conventional vehicles. The so-called energy-absorbing zone has a key role during an accident. In the era of modern materials the aluminum foam can works as an energy-absorbing structure. However, the machining of this material is hard at this time. This article attempts to investigate, through Computed...

Condition Monitoring of Wind Farm based on Wireless Mesh Network

Since the last years of twentieth century the use of wind energy rapidly increased and it is imposed as one of the best alternatives to burning fossil fuels. Nowadays, in renewable energy resources, wind energy is the leading candidate for electricity production due to its lower investment cost and well-developed technology in manufacturing high-power wind turbines. Basing on a Reliability Centred Maintenance (RCM) analysis, this paper focuses on the use of a Wireless Mesh Network in order to monitoring several condition parameters to identify possible incipient failures analysing the...
