Keywords: Assembly, Robot, Human-robot collaboration |
Abstract : In human-robot collaborative assembly, robots are often required to dynamically change their pre-planned tasks to collaborate with human operators in
a shared workspace. However, the robots used today are controlled by pre-generated rigid codes that cannot support effective human-robot
collaboration. In response to this need, multi-modal yet symbiotic communication and control methods have been a focus in recent years. These methods
include voice processing, gesture recognition, haptic interaction, and brainwave perception. Deep learning is used for classification, recognition and
context awareness identification. Within this context, this keynote provides an overview of symbiotic human-robot collaborative assembly and highlights
future research directions.

Keywords: Metal forming, Integration, Smart tooling |
Abstract : Forming is widely used due to its high efficiency in material utilization and its high production rate in general. Most forming processes control the
geometry of final products through a set of tooling. The increasing demands on lightweight products have challenged the performances and
functionalities of tooling. This paper provides a systematic review of recent advancements related to tooling performance and functionalities, including
tool materials, tooling fabrication processes (e.g., machining, heat treatment, coating, surface texturing, and additive manufacturing), sensing, and data
analytics. Finally, recommendations on future research directions for metal forming tooling are provided.

Keywords: Design, Product development, Model-based systems engineering |
Abstract : Smart products supported by new step-changing technologies, such as Internet of Things and artificial intelligence, are now emerging in the market.
Smart products are cyber physical systems with services through Internet connection. For example, smart vehicles equipped with advanced embedded
intelligence are connected to other vehicles, people, and environment, and offer innovative data-driven services. Since smart products are softwareintensive, data-driven, and service-conscious, their development clearly needs new capabilities underpinned by advanced tools, methods, and models.
This paper reviews the status and trends of these emerging development technologies such as model-based systems engineering and digital twin.

Keywords: Process monitoring, In-process measurement, Visualization |
Abstract : This paper aims to visualize spatio-temporal phenomena in electro physical and chemical processes in order to understand machining mechanisms and
to achieve a technological breakthrough. In situ measurement methods to visualize the time evolution of stress, strain, temperatures, fluid velocities, and
species density distributions, together with 2D or 3D images of the workpieces being processed are summarized. Applications of these methods to
fundamental studies on electrical discharge machining, electrochemical machining, laser processing and additive manufacturing are introduced. Signal
recording and processing technologies and real time monitoring enabling closed-loop feedback control are also discussed.

Keywords: Modelling, Metal forming, Process limits |
Abstract : Modelling of metal forming processes is an essential task of production engineering. Due to the latest technological developments, a huge variety of
models is already available and extending continuously. Thus, it is important to find a suitable model. This paper gives an overview on the common
classification and characterization of modelling and models in metal forming, as well as introduces a model selection procedure. Based on this
classification, various relevant process limits for metal forming are investigated regarding existing models. The conclusion of the paper shows open
topics as well as upcoming challenges in modelling process limits in metal forming.

Keywords: Micro machining, Miniaturization, Micro structures |
Abstract : The demand for miniaturized products and functionalized parts is increasing, and many such products are made of hard and brittle materials
machined by abrasive processes. The first part of this keynote paper is dedicated to a discussion of micro parts and micro structures machined –
at least in part - by abrasive processes, followed by a discussion of the associated abrasive processes. The strengths and limitations of these
processes, among which include dicing, micro grinding, micro abrasive blasting, and vibration and magnet field assisted finishing are discussed.
The paper concludes with a discussion of future trends in the field.

Keywords: Robot, Machining, Process planning, Control |
Abstract : Robotic machining centers offer diverse advantages: large operation reach with large reorientation capability, and a low cost, to name a few. Many
challenges have slowed down the adoption or sometimes inhibited the use of robots for machining tasks. This paper deals with the current usage and
status of robots in machining, as well as the necessary modelling and identification for enabling optimization, process planning and process control.
Recent research addressing deburring, milling, incremental forming, polishing or thin wall machining is presented. We discuss various processes in
which robots need to deal with significant process forces while fulfilling their machining task.

Keywords: Production, Network, Global Production |
Abstract : Industrial companies are nowadays acting in global production networks (GPNs). A comprehensive scientific overview of those networks is still missing.
To close this gap, a framework for designing and operating GPNs is introduced. It structures influencing factors, challenges, enablers and outlines the need
for decision support systems. The state of the art in designing and operating GPNs is reviewed. Three trends are identified that help to transform historical
grown networks into changeable GPNs with a focused network footprint. In conclusion, a need for future research in forming the production strategy,
designing the network footprint and managing the network is given.
