Keywords: Life cycle, Circular Economy, Absolute sustainability |
Abstract : The global society faces an existential threat if it fails to meet current and future material needs of its populations, while staying within
the carrying capacity of our planet. An approach that has been put forwards to address this complex challenge is to aim to close our
society’s material flows through introduction of a Circular Economy (CE). This paper provides an extensive literature review to
understand the evolution of material circularity concepts and strategies, and their potential for increasing material efficiency and reduce
environmental impacts towards meeting the material needs of our societies in an environmentally sustainable manner. Based on the
review it can be concluded that CE may have a strong potential to help address the challenge. However, this requires broadening the focus
of CE from technical and economical to political and socio-cultural dimensions, adopting a whole-systems approach, aiming to redesign
economic and social relations to not just reduce the impact humanity has on the environment but actually achieve a balance in humannature
relations with a planetary boundary thinking. Pursuing purely technical and economic avenues to implement CE for increasing
material circulation and sustainable growth on the foundation of our current linear economic system, will not achieve its full potential. It
will not be sustainable but continue to produce the challenges that we currently have.

Abstract : This keynote paper mainly focuses on advancements of machining technology and systems for enhanced performance, increased system integration and
augmented machine intelligence, critically hinging on new sensors, sensor systems and sensing methodologies being robust, reconfigurable and intelligent,
while providing direct adoption and plug-and-play use in industrial practice. One chief novelty is given by the key enabling technologies of Industry 4.0
where integration of sensing systems in manufacturing plants is a cornerstone for transforming conventional manufacturing concepts into digital
manufacturing paradigms. Application examples to industrial processes, future challenges and coming trends in machining monitoring are shown.

Keywords: Design, Service, Value creation |
Abstract : Industrial Product-Service Systems (IPS²) have been increasingly researched and practiced in a variety of fields and sectors. Nevertheless, such
solutions are not as significantly implemented as expected by the CIRP keynote in 2010: it is not a dominant business of manufacturing companies
today despite their economic and environmental advantages. One reason for this delay is assumed to be that the initial efforts were mainly on
business and service when design was an afterthought. The promising digital technologies that have become easily implementable in practice will
in the next years facilitate design and implementation of IPS² smartly to satisfy users and contribute to sustainability. This keynote analyses
literature and practice in the last decade, aiming to propose the main characteristics of IPS² of the future and design processes adequate for IPS².
The design process of both production systems for sustainability and high-value systems for sustainable development goals may need to be supported
differently than today. The list of recommendations for future research on IPS² design is provided at the end of the paper.

Keywords: Simulation, Metal forming, Modelling, Visualization, Digital twin |
Abstract : The simulation of manufacturing processes has significant importance. The research and development of metal forming simulation started in the 1960s
from the elastoplastic analysis of a simple plastic deformation, and it now covers a wide range of forming processes. The accuracy and applicability of
metal forming simulation have significantly progressed, driven by the development of plasticity theory and numerical methods such as the remeshing
technique and contact analysis algorithm. Now the targets of metal forming simulations are undergoing a transition from the macroscale analysis of
deforming bodies to coupled analyses of deformations of deforming bodies and tools, and multiscale analyses of microstructure and texture. Past
achievements of metal forming simulation show that it has reached the level of ‘visualizing forming phenomena’, but it will continue to evolve in the
digital era, impacting the digital society and factories of the future, where machines work autonomously without human intervention. Emergent
technologies require advanced materials, augmented reality, and, of course, metal forming simulation. In this paper, we reinforce the role of simulation
as a means of performing computational (virtual) experiments and as a tool for the high-fidelity numerical visualization and quantification of unknown,
unmeasurable, and invisible phenomena in formed components and their assembly. We will also discuss simulation–machine interactions, such as online
simulation with process operation, to realize the triad of ‘process operation – data – simulation’ in the near future.

Abstract : Because of their many applications, including automotive, aeronautics, optics, and so forth, demand for grinding tools sees unabated growth. But the energy
and resource intensive nature of their manufacture leads to questions of sustainability. This paper details how recent developments in basic tool technology
(structure, binder, abrasives) is increasing tool and abrasive resilience while reducing production inputs. The advent of smart grinding tools involving
aspects of surface engineering, process hybridization, and process monitoring is also discussed. The paper concludes with an outlook of further energy
savings, tool recycling and uses of additive manufacturing with the aim of achieving long-term sustainability.

Keywords: Production, Synthesis, Domain Randomization, Industrial Revolution |
Abstract : Optimisation of factories, a cornerstone of production engineering for the past half century, relies on formulating the challenges with limited degrees of
freedom. In this paper, technological advances are reviewed to propose a “daydreaming” framework for factories that use their cognitive capacity for
looking into the future or “foresighting”. Assessing and learning from the possible eventualities enable breakthroughs with many degrees of freedom and
make daydreaming factories antifragile. In these factories with augmented and reciprocal learning and foresighting processes, revolutionary reactions to
external and internal stimuli are unnecessary and industrial co-evolution of people, processes and products will replace industrial revolutions.
