Keynote: The value of user focused design, exemplified through a collaborative process for developing learning arenas
Time : 09:00AM to 09:30AM
Petter Øyan, professor of industrial design. Graduated from Hochschule für Gestaltung, Schwäbisch Gmünd, Germany 1981. More than 20 years of international, professional design experience as freelance design consultant and partner in a product design consultancy. Broad portfolio of product development projects, ranging from office workspaces to laboratory instruments, and from international enterprises to technology start-ups.
Industrial Design uses a wide range of tools and processes to explore and identify the behaviour, needs and wishes of the users of products and systems, and based on analysis of this information develop innovative solutions and products. Fast technological and societal development leads to faster changes in the development of workspaces and learning arenas. Working life and education becomes more global and consequently more competitive, or even collaborative. It is therefore necessary to understand the “user group” our students represent, and the work practices they bring with them from earlier education as well as the expectations they have for their futur e working world. Digital workspaces make a good case for experimenting with design processes. To get relevant information to feed into the development of our learning facilities, we have set up a series of projects where students in the role of designers are coached through a collaborative design process involving students, teachers and the university administration, as well as suppliers of technology and equipment. There are several models for the over-all design process as well as for the different phases of a project, suitable tools must be chosen according to the assignment, the framework and the task. The concepts and recommendations are lifted into our real development process, analysed and tested by prototyping, to give feedback on the quality of user interaction with objects and systems, physically and emotionally. I will present this process and analyse the value for our facility development.
University of Stuttgart, Germany
Keynote: Manufacturing engineering in thermal spray technologies by advanced robot systems and process kinematics
Time : 9.30AM - 10.00AM
Prof. Gadow has completed his M.Sc. and PhD both in chemistry at the University of Karlsruhe (T. H.), Germany, now KIT. As assistant professor he was head of the ceramics and composites group at ICT, University of Karlsruhe. In his industrial career he was head R&D and general manager in world leading companies in technical ceramics, surface technologies and advanced mechanical engineering. Since 1995 he is full professor and managing diretor of IFKB, the institute of manufacturing technologies of ceramic components and composites at the University of Stuttgart, Germany. He managed various national and international projects in advanced cermics, surface and nano technologies. He is the acting dean of the faculty of mechanical, automotive and production engineering with 17 research institutes in Stuttgart. Furthermore he is managing director of New Materials Technologies at TTI GmbH, Stuttgart. He has published more than 700 papers in reviewed journals and more than 60 patents in the field of product development with new materials and manufacturing processes. He is serving as an editorial board member and peer reviewer of various scientific journals and visiting professor worldwide.
Plasma physics and material science have dominated academic research in thermal spray technologies in recent decades. Value adding by creation and manufacturing of competitive products with advanced coating technologies employed needs a state of the ar t approach in manufacturing engineering . Thinking in process chains and managing all steps of them with a focus on product performance, reliability and customer satisfaction is an indispensable methodology for modern manufacturing engineering with complex high technologies. Materials mechanics and the understanding of process induced residual stresses and their interaction with operational load stresses are further issues in product development of coatings and layer composite structures. Intensive heat and mass transfer up to supersonic conditions have a distinct influence on coating properti es. The same is true for the torch trajectories and robot kinematics programming with their influence on local resolution of these parameters and subsequently on the achievable dimensional tolerances and reproducibility in industrial processes.rnFor high process reproducibility and optimized coatin g quality in thermal spray applications on complex geometries, APS ( Atmospheric Plasma Spraying ), HVOF (High Velocity Oxygen Fuel) and further torches are guided b y advanced robot systems. The trajectory of the torch, the spray angle and the relative speed between torch and component are crucial factors which affect the coating microstructure and phase composition as well as the mechanical, th ermophysical and electrophysical properties and especially the residual stress distribution. Thus the requirement of high performance thermally sprayed coatings with narrow dimensional tolerances leads to challenges in the field of robot assisted handling, and software tools for efficient trajectory generation and robot programming are demanded. By appropriate data exchange, the automatically generated torch trajectory and speed profile can be integrated in FEM (Finite Element Method) models in order to analyze their influence on the heat and mass transfer during deposition.rnLast not least the process variants have to be matched to meet the best fit of functional requirements of the coating product in its specific application field. Modeling and simulation concepts are shown to demonstrate their potential and benefit for industrial product development. Case studies are introduced in the fields of new combustion e ngines, ship propulsion and nuclear power plant engineering.
