The multiple facets of modern sheet metal manufacturing techniques are applied throughout a wide spectrum of economy, ranging from the automotive industry and machine manufacturing to electrical engineering and electronics. This wide range of applications means that sheet metal manufacturers produce parts from a few grams up to 1,000 kg and more, from electrotechnical parts up to components in automotive industry, as well as batch sizes ranging from just at a few pieces to mass production. Worldwide, around 12,300 companies employing 600,000 workers produce sheet metal goods worth over 732 billion US dollars (all numbers reflect the situation in 1999). These are impressive numbers for sheet metal manufacturing, to which forming processes are central, but also for cutting and joining technologies with their increasing importance. All of these processes have developed dynamically in the recent past, and this trend will no doubt continue. The automotive industry is the main impetus worldwide for new developments as is seen in its efforts to optimize lightweight constructions. Basic research at universities has been instrumental in promoting new developments through a better understanding of materials and processes. As we are standing at the very beginning of a new millennium, a new achievement profile for the sheet metal industry is emerging which will foster a fast and economical product development process.
One such interdisciplinary arena is promoting the close cooperation between material scientists, technologists, manufacturing engineers and computer scientists in academia and industry. This cooperation is supported by the SheMet conference Series, which was founded in Birmingham, England, in 1993, and since has been hosted in yearly rotation by the University of Central England in Birmingham, the University of Ulster at Jordanstown, Northern Ireland, the University of Twente in the Netherlands, the Institute of Manufacturing Technology of the Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany.
From 2001 onward, the conference has moved to a biennial schedule, furthermore the KU Leuven, Belgium and the University of Palermo, Italy have joined the group of organizers whereas the University of Twente and Birmingham City University have stopped hosting the conference.

Novel laser technology opportunities in processing sheet metal
Over the last decades, lasers have been adopted in a wide spectrum of sheet metal processing applications and they represent a core production technology of modern process lines. Nevertheless, challenges, which cannot be opposed by established system technology, arise for instance due to new materials and material pairings, the electrification in the automotive industry as well as the demand for traceability in the digital production process. Therefor these challenges state some of the main driving forces for new technologies in the field of laser materials processing. Due to this, for example new beam sources, more advanced processing optics, but also new sensing technologies are developed and made industrially available. One example for this are the variety of solutions for increasing the weldability of copper or the increased number of remote processing applications. The novel technologies not only serve the demand from industry, they also open up new opportunities. For example, the faster beam deflection allows avoiding defects by beam oscillation during the process. In addition to that, the available system technology can be used to reach not yet used process regimes to realize processes with an increased economic and ecologic efficiency like remote cutting. In the near future uprising technologies, like beam shaping, will open up a complete field of opportunities by making additional degrees of freedom available for the realization of innovative laser applications in sheet metal processing.

New trends in coin minting
Although the creativity of sculptors plays an important role in the development of new proof coins for collection purposes, it is nowadays impossible to produce innovative collector coins without a serious commitment to technological development. The convergence of recent trends in numerical simulation of coin minting, in advanced coin minting presses and in the utilization of other materials than those usually taken from groups 10 and 11 of the periodic table are pushing the limits of innovation in coin minting. The consequence of all this is that coin minting has evolved to such a level of complexity that some of the geometries, materials and techniques used in newly minted proof coins would simply be out of consideration two or three decades ago.
With this in mind, it is the purpose of this presentation to provide a state-of-the-art review in science and technology of coin minting and to introduce some of the actual trends in the production of collection coins. Special emphasis is placed on innovative design techniques, new materials and joining processes. Two examples will be comprehensively discussed. Firstly, the development and application of finite element based design procedures for correcting the coining die profiles and extending their service life. Secondly, the development of a new polymer-metal coin that is produced by combination of coin minting and joining by forming in a single die stroke. The utilization of coining disks made from sandwich composites with the purpose of obtaining new aesthetic effects and/or incorporating advanced security features will be also discussed.

Numerical modelling issues and strategies on sheet metal forming simulation
The optimization of products and processes, as well as short development times, requires intensive use of numerical frameworks and tools for virtual testing. There is a multitude of software packages designed to help engineers, mostly resorting to Finite Element Analysis (FEA) with the common aim to provide accuracy and simultaneous efficiency and offering a diverse library of finite elements and material laws for distinct simulation needs. This talk provides an overview of common numerical pathologies and issues related to the simulation of sheet metal forming processes. Applied examples will show the importance of carefully choosing some model and simulation parameters in order to obtain results in a fast and reliable way.

XXL Profile Bending
Bending XXL boom profiles and large radius shells for markets such as yellow goods, transportation and offshore is traditionally a highly labour-intensive process that involves multiple setups and part handlings to achieve an accurately formed part. As such, productivity suffers and the risk for error and operator injury is high. Though bending technology has made significant strides in reducing press brake set up time and improving the accuracy and repeatability of forming, these jobs remain a challenge fundamentally because of their XXL size. The advent of new high-strength materials with tensile strengths up to 1,300 MPa and higher, small batch production, tight tolerances and falling skill levels in the work shop have added to the challenges of XXL bending.
In this presentation we examine the current demands and trends in XXL bending and introduce an award-winning adaptive bending solution, Synchro-Form. Synchro-Form addresses the challenges of large-profile bending, making it possible to bend large profiles with consistent accuracy, at high throughput and with minimal operator intervention. This next-generation adaptive bending technology is changing XXL bending. By using an in-process quality management system to measure the accumulated angle and compensate for angle deviation in the bends that follow, this advanced technology can improve productivity of large profile bending up to 50% or more, depending on the specific profile. An example of an XXL bending application in the aerospace sector will be featured, detailing Synchro-Form technology in action.
Trained in electromechanical engineering (VHTI – Kortrijk), Steven Lucas began his career 24 years ago at LVD, a renowned Belgian manufacturer of press brakes and shears, punch presses, laser cutting machines, software and modular automation. Steven advanced from a field engineer position with LVD’s World Service team to international Sales Manager. Because of his solid experience in bending technology and proven skills in key account management, he was appointed Press Brake Product Manager in 2008. In this capacity, Steven is responsible for the international press brake sales team and is involved in sales activities with key accounts across the globe. Integral to his role is keeping abreast of market trends and technology.
Steven’s strong interest in new technologies and close work with customers has often incited LVD to develop and implement technical innovations, such as the customized Synchro-Form press brake, especially developed for Kawasaki Heavy Industries and their work with aviation giant Boeing. As a result, LVD is recognized as a world leader in bending.
Prediction and validation of forming limits in sheet metal forming with non-proportional load histories
Due to the increasing customer demands on quality, safety, lightweight and design, more and more complex sheet metal parts have to be produced. In order to overcome the resulting challenge of time pressure, Finite Element Analysis are of utmost importance for production technology. For those models a profound knowledge about the material is essential. One of the main objectives in sheet metal forming simulations is the feasibility prediction limited by localized necking.
The forming limit Curve (FLC) is a conventional model to estimate the forming limits of sheet metals for proportional loading conditions in Finite Element Analysis. Previous studies found that a standard linear Forming Limit Curve is not suitable for predicting the influence of non-proportional load histories. Models to address this problem are i.a. the Generalized Forming Limit Concept (GFLC). Those models require reliable databases and profound knowledge about the material.
The Generalized Forming Limit Concept is purely based on measurable data, which is why no material model has to be used to assess complex strain paths regarding formability. Nevertheless, the bi–linear material tests, which are needed as database, e.g. Nakajima tests or cruciform specimens, have to guarantee precise results. By analyzing an acceptable number of bi–linear experiments it is possible to calibrate the phenomenological GFLC model. Therewith an arbitrary load history can be evaluated with respect to localized necking. The cost effectiveness of the approach is given through the possibility of scaling the results. Non–proportional load histories of materials within the same material class can be estimated without any individual experiments for model fitting. Only a linear forming limit curve is needed.
