Abstract
The proposed research program integrates four for the modern manufacturing key research fields. In next, the research topics related to each field are outlined.   Production systems. Research into new manufacturing concepts of distributed manufacturing systems, including structuring and control and based on the principles of autonomy, self-organization, self -earning, cloud manufacturing, internet of things and Big Data will be performed; the principles of product-service systems, on-line monitoring and remote control, production of personalized products will be investigated; applications of mechatronics and cyber-physical systems will be developed; principles of concurrent product developed will be researched.   Laser systems. Development will include fiber and hybrid laser sources which are suitable for high precision machining; and pulsed laser sources with pulse duration in the range of ns and sub-ns. Research of laser measuring systems will include systems for simultaneous 3D shape and color measurement of bodies in real time. Research will also be focused adaptive control of laser systems and on the development of new opto-mechatronic systems based on optical elements with free surfaces, electrically focus-tunable lenses, and microlens arrays.   Laser machining processes, surface modification and non-destructive testing. Research will focus on the development of new laser machiningprocesses related to surfaces modification to improve mechanical properties and their applications. The focus of the research will be on optimizing the various laserprocesses in terms of surface integrity, which requires the study material properties and individual components with regard to material changes caused bythe process parameters. It will be developed a method for non-destructive based on acoustic emission signals. The testing method will be developed for monitoring of die-casting process of reinforced polymeric materials. New challenge will betesting of glued joints of the same or different types of materials by means of ultrasound. Joining of materials. Research will be focused on weldability of dissimilar materials; repair welding of tools to extend the in-service tool life; development of filler materials for repair welding and additive manufacturing; additive manufacturing using a welding robot; friction stir welding and processing; and on different joining technologies.    The proposed topics are highly relevant for advances of manufacturing science as well as for the economic and social development of Slovenia. The research will be conducted in a close relationship with industry. The researchers will also look for cooperation on international projects within the European research initiatives and broader. The research goals will be primary directed into transfer of new knowledge into industry and medicine, as well as in publishing research papers in prestigious scientific journals.
Significance for science
(I) Production systems. The research will build on previous excellent results in the areas of manufacturing system structuring, management of manufacturing complexity, and personalized tools for planning and carrying out medical procedures. Within the program, these results will be upgraded with new theories of distributed manufacturing, focusing on cloud computing and social aspects – the role of humans in the factories of the future. New organizational and business models for product-service systems will be developed, along with associated systems for product personalization such as collaborative environments, adaptive manufacturing systems, and measurement systems. An overview of existing research at home and abroad shows that for the success of the product on the global market the important elements are: time, quality and high added value. Designing a general model of lean six sigma process of concurrent product and process development will require the use of new scientific approaches that will bring together very different concepts.   Within the program section (II) Laser Systems a new generation of laser systems with enhanced capabilities, particularly in respect of energy efficiency, reliability, security and the ability to manufacture new products will be developed. It is expected that the ultrafast fiber lasers will open new fields of micro-and nano manufacturing processes. Developed monitoring methods of laser machining processes will enable optimization of laser processes and spreading to new areas of application. By developing of systems for3D shape and color measurement in real-time, the development of new diagnostic methods, particularly in the areas of orthopedics, pulmonology and dermatology is expected. Furthermore, we expect that the mutual integration of laser measurement and machining systems will enable new solutions to design of small-series and personalized products. Research in the field (III) Laser machining processes, surface modification and non-destructive testing, will yield new insights and their application in the most complex structures. The results will enable accelerated introduction of newer techniques for finishing surfaces in production or in use. Based on the research results it will be possible to conduct a new process with higher quality in terms of surface roughness, mechanical properties and corrosion resistance.   (IV) Joining of materials: New findings in the field of joining dissimilar materials will contribute to the development of science and offer high-quality publication in journals with high SCI. We expect that the importance for the development of science will be achieved in the field of joining Al and Cu for the needs of volume production in automotive and electrical industry with the procedures of the hybrid welding, FSW and in repair welding of tools. Institut za varilstvo: The greatest significance for testing of joining of materials research is applicability and optimization of the existing theoretical principles.
Significance for the country
(I) Production systems. The research will be carried out in collaboration with industry, which will allow for direct transfer of research results into industrial practice and, in turn, significantly contribute to the socio-economic development on Slovenia. Furthermore, it will be performed through international projects, and promoted in scientific and professional conferences in Slovenia and abroad. Research in the field of personalization of medical devices will lead to cheaper medical tools, as well as cheaper and more efficient execution of medical procedures. Research results will be included in the eductional process at all levels of study. The lean six sigma process of concurrent product and process development will allow especially small and medium-sized Slovenian companies to (despite the limited human resource potential) successfully develop products – fast, with low cost, high quality and high added value.   Activities of the program section (II) Laser Systems will take place in the wider context of research which is already established with our industrial and medical partners. These are internationally recognized companies (Danfoss, LPKF, RLS, Alpina, Yaskawa, Hidria, etc.) and academic institutions (UKC-LJ , UKC-MB , Golnik Hospital, etc.) that significantly invest into human resources, and into development of new systems, products and services. In this context the Laser Systems allow a general increase of technological knowledge which is further transmitted to all other branches in Slovenia and abroad. The research will also contribute significantly to the creation of new high-added-value jobs. This provides opportunities for a technological breakthrough of Slovenia in the field of high-added-value services and processes. New laser systems will allow considerably lower ejection of products and will speed-up the production process. Further, 3D real time body measurement will enable the introduction of laser measurement systems as part of routine medical tests that will contribute to improving the reliability of treatment. The Slovenia’s international competitiveness in will therfore be significantly increased. (III) Laser machining processes, surface modification and non-destructive testing. Slovenia will achieve higher quality and pricing of products with the introduction of advanced technology surface treatment, and will be a global competitor in this field. These new technologies are widely used worldwide in the automotive and process-chemical industry as well as in the aerospace industry. For Slovenia would represent a huge impact the deployment of these new technologies in the automotive industry and for the manufacture of a variety of metallic implants in medicine.   (IV) Joining of materials: Working closely with industry in R&D of joining technologies at (1) the development of new smaller and lighter multimaterial products with longer in-service life (glow plugs - Hidria AET, commutator – Kolector, joining of different Al alloys), (2) extending the in-service life of industrial tools (toolmakers and foundries), and (3) R&D in the field of friction stir welding and processing for development of superplastic Al alloys will increase: the value added of existing or new products, employability of young people of both sexes, value added per employee, lower power consumption and less emissions and a competitive advantage to companies. The increase in revenues in the industry will increase investment in infrastructure; greater employability will increase consumption and lead to economic growth. Cleaner technologies will enable greater protection of natural and cultural heritage. Institut za varilstvo: There are several top companies in Slovenia, which will gladly use our developed technology on their products. The Welding Institute, which annually participates with over 700 Slovenian companies, is the best link between design and practice.
