  text: 'Additive Manufacturing (AM) has been growing rapidly with doubledigit growth
    rates during the last years and a rising trend towards end products. The further
    development of the technology highly depends on some critical success factors.
    For the future, it is vital to know which innovations will be necessary to satisfy
    the needs of industry. The impulsive forces will be those branches whose special
    characteristics are met by AM. Within the DMRC study “Thinking ahead the Future
    of Additive Manufacturing – Analysis of Promising Industries” (Gausemeier 2011),
    especially aircraft production, automotive production and the electronics industry
    have been identified as very promising to profit from the use of AM. Experts have
    selected these branches by assessing the prospective attractiveness of current
    application fields. Those branches are characterized by low quantities, complex
    part designs, lightweight design and/or high unit prices. For the aerospace industry,
    all four elements are of high relevance, which is why it has been a pioneer in
    applying and developing AM technology since the early beginning (Gausemeier 2011
    and 2012). '

  text: 'Additive Manufacturing (AM) is often deemed to be a driver for product piracy
    in public media. The reasons for this are mainly seen in the fact that it provides
    a possibility to easily copy three-dimensional objects when used in combination
    with scanning technologies. This contribution will not focus on the knowledge
    and skills needed to master AM technology but on its potential contribution to
    prevent product piracy and reverse engineering. The reverse engineering process
    will be analyzed to understand the practice of imitators and to transfer the characteristics
    of AM into specific measures. Finally a five-step methodology is presented which
    can be used as a guideline to implement protection measures in products to be
    (re-) developed. This guideline is supposed to be used by industrial companies
    since an expert survey has identified them as being very likely to profit from
    the use of AM (Echterhoff et al. 2011). '

  text: Nowadays, the material efficiency and part reliability are two majorissues
    in product development. Thus a product optimization often requires complex structures
    that are hard to be manufactured conventionally. Additive Manufacturing (AM) however
    offers great potentials for producing complex shaped parts economically. Different
    approaches are feasible to exploit these potentials based on the part’s application
    from shape optimization of structural components to the integration of functions
    and other entities of assemblies. Several parameters are defined that influence
    the costs and quality of the future product and carefully have to be balanced.
    To do so, the use of already known tools for the optimization and design needs
    to be reconsidered and adapted to the special characteristics of AM. As not all
    optimization potentials can be realized perfectly, a decision methodology is required
    to obtain the relevant potentials and to get to a trade-off between all requirements
    including the ecological impact. The paper shows different approaches for product
    optimization with AM and procedures for decision making in order to get to the
    optimal solution.

  text: Additive Fertigungsverfahren bieten in der Luftfahrtindustrie großes Potential.
    Die Geometriefreiheit ermöglicht die Produktion von komplexen und gewichtsoptimierten
    Bauteilen. Die mangelnde Erfahrung der Unternehmen mit dieser Fertigungstechnologie
    erschwert jedoch die Entscheidung, an welcher Stelle Additive Manufacturing ökonomisch
    sinnvoll eingesetzt werden kann. Die Kosteneinflussfaktoren unterscheiden sich
    an vielen Stellen von denen traditioneller Fertigungsverfahren und müssen gänzlich
    neu bewertet und eingeordnet werden. Dabei verlagert sich auch der Fokus weg von
    den reinen Herstellkosten hinzu einer ganzheitlichen Kostenbetrachtung. Wesentliche
    Vorteile lassen sich auch meist in der Supply Chain erzielen und müssen im Zuge
    des Entscheidungsprozesses für ein Fertigungsverfahren bei einem bestimmten Bauteil
    berücksichtigt werden. Daher werden in der Präsentation die Charakteristika der
    Luftfahrt analysiert und die Methodik einer Entscheidungsunterstützung vorgestellt.
    Im Zuge dessen gilt es die Kostenbewertung additiver Fertigungsverfahren näher
    zu beleuchten, um die Fertigungs- bzw. Reperaturkosten mit traditionellen Verfahren
    vergleichen zu können. Weiterhin müssen Veränderungen in der Supply Chain identifiziert
    und bewertbar gemacht werden. Qualitätskriterien müssen ebenfalls mit in die Betrachtung
    einbezogen werden. Anschließend wird aufgeziegt wie diese Einflussfaktoren in
    die Entscheidungsunterstützung integriert sind.

  text: The mechanical characterization of fused deposition modeling (FDM) parts is
    mostly done by static tests. In many applications, parts are also dynamically
    loaded. Here, fatigue tests can help to identify the expected lifetime of a part.
    This article discusses the fatigue behavior of FDM specimens manufactured with
    Ultem 9085. For this, tensile bars are manufactured according to ASTM D638 in
    different build orientations. Tests are performed in a range of pulsating tensile
    stresses, and S-N curves are documented for different build orientations. For
    higher loads, the FDM anisotropy characterizes the lifetime of used specimens,
    which is similar to static tensile bars. For lower loads, including a higher number
    of cycles to failure, S-N curves of different build orientations converge. In
    further tests, tensile bars were chemically smoothed with chloroform vapor. Chemical
    smoothing reduces surface roughness and increases tensile strength of specimens
    in the upright build direction. Fatigue tests of chemically treated specimens
    show no significant lifetime increase.

  text: Das Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS etablierte in
    enger Kooperation mit Partnern in den letzten Jahren erfolgreich eine geschlossene
    Technologiekette zur Umsetzung maßgeschneiderter mikrophysiologischer Systeme.
    Darauf aufbauend wurde eine universelle Mikrobearbeitungsplattform zum automatisierten
    Fertigen konzipiert und entwickelt. Dies umfasst neue Technologien für Schlüsselprozesse
    wie das Herstellen mikrofluidischer Komponenten mittels ARBURG Kunststoff-Freiformen
    sowie das Erzeugen funktionaler Strukturen und das Einbringen von Produktschutzmerkmalen
    auf innenliegenden Polymergrenzflächen mittels Direktem Laserinterferenz-Verfahren.

  text: The material Ultem 9085 is a flame-retardant thermoplastic polymer, which
    can be processed with Fused Deposition Modeling (FDM). Due to ist high strength-to-weight
    ratio and FST rating, Ultem 9085 parts are used in aviation. Process related staircase
    effects on rounded and slanting part areas require a surface treatment for end
    use parts. These processes include smoothing by mass finishing or coating in order
    to reduce surface roughness. An alternative smoothing technique is chemical surface
    treatment, such as the use of Acetone for ABS materials. In this paper, the surface
    of Ultem 9085 parts is treated with Chloroform vapor in order to solve material
    at the surface and smooth it. Therefore, specimens built in different build orientations
    are treated and tested with regard to surface roughness values and mechancial
    strength properties. The analysis of surface roughness and treatment time shows
    a significantly higher efficiency for chemical treatment in comparison to mass
    finishing. By employing chemical treatment, it is possible to reduce surface roughness
    by more than 80 % to Rz values of approximately 15 µm. Mechanical tests and measurements
    of the Melt Volume Rate (MVR) show no material destruction for chemical surface
    treatment at room temperature for less than 150 min.

  text: Wire bonding has been an established packaging technology for decades. When
    introducing copper as wire material for high power applications, adaptations to
    the bonding process and to machines became necessary. Here, challenges occur due
    to the stiffer wire material and changing oxide layers on the contact partners.
    To achieve sufficient process stability, a clean bond area is required, which
    can only be achieved with high shear stresses in the contact partners surfaces.
    These necessitate high normal forces to plastically deform the wire and substrate.
    To achieve such high stresses in the contact area, the bonding tool needs to be
    able to transmit the needed tangential forces to the top side of the wire. The
    wire itself performs a shear movement and transmits the force into the contact
    area to clean the contaminant and oxide layers and to level the desired bond surfaces.
    The main function of the tool is to transmit these forces. If the bond tool can
    only transmit low forces in the direction of excitation, the parameter space for
    a stable bond process is severely restricted. Here, a modeling approach to estimate
    how well different tool shapes meet the demand of transmitting high tangential
    forces is presented. The model depends on wire deformation and thus on the ultrasonic
    softening effect.

  text: The transportation of dry fine powders is an emerging technologic task, as
    in biotechnology, pharmaceutical or coatings industry particle sizes of processed
    powders are getting smaller and smaller. Fine powders are primarily defined by
    the fact that adhesive and cohesive forces outweigh the weight forces. This leads
    to mostly unwanted agglomeration (clumping) and adhesion to surfaces, what makes
    it more difficult to use conventional conveyor systems (e. g. pneumatic or vibratory
    conveyors) for transport. A rather new method for transporting these fine powders
    is based on ultrasonic vibrations, which are used to reduce friction and adhesion
    between powder and the substrate. One very effective set-up consists of a pipe,
    which vibrates harmoniously in axial direction at low frequency combined with
    a pulsed radial high frequency vibration. The high frequency vibration accelerates
    the particles perpendicular to the surface of the pipe, which in average leads
    to lower normal and thereby smaller friction force. With coordinated friction
    manipulation the powder acceleration can be varied so that the powder may be greatly
    accelerated and only slightly decelerated in each excitation period of the low
    frequency axial vibration of the pipe. The amount of powder flow is adjustable
    by vibration amplitudes, frequencies, and pulse rate, which makes the device versatile
    for comparable high volume and fine dosing using one setup. Within this contribution
    an experimental set-up consisting of a pipe, a solenoid actuator for axial vibration
    and a piezoelectric actuator for the radial high frequency vibration is described.
    An analytical model is shown, that simulates the powder velocity. Finally, simulation
    results are validated by experimental data for different driving parameters such
    as amplitude of low frequency vibration, pipe material and inclination angle.

  text: Ultrasonic heavy wire bonding is a commonly used technology to conduct electrical
    devices in power electronics. In order to facilitate powerful solutions combined
    with an increased efficiency, involving a material change from aluminum to copper
    wire as conductor material takes place in recent years. Due to the material related
    properties, copper wire bonding requires significant higher bond processing parameters
    such as bond force and ultrasonic power compared to aluminum which can lead to
    damages or a failure of the bonded component. Therefore, a profound knowledge
    of the processes prevailing during wire bonding is essential to optimize the application
    of the copper wires and consequently to achieve the demands on quality and reliability.
    The behavior of different natural surface oxides of aluminum and copper are assumed
    to be one reason for the deviation in the required bond parameters. Accordingly,
    the impact of differently pre-treated substrates surfaces on which the bonding
    is applied were investigated in this study. First, all conditions investigated
    (as-received, oxidefree, AlOx and the CuOx) were characterized by utilizing scanning
    electron microscopy, energy dispersive X-ray spectroscopy, focused ion beam microscopy
    and atomic force microscopy. In addition, hardness tests were performed as well
    as perthometer measurements. Afterwards, a 500 $\mu$ m copper wire was bonded
    on the generated surfaces investigated. In consideration of the roughness, shear
    test of various bond times and microscopic images were evaluated. Finally, the
    results were compared and discussed. Overall, the current study indicates that
    an Al-oxide layer is beneficial for welding process in Cu wire bonding. On the
    contrary, the Cu-oxide is detrimental and leads to a delayed welding of the joining
    parts. Based on the obtained results, it can be expected that due to an ideal
    set of Al-oxide layers, lower optimal bond parameters can used to reach high bond
    strength with good reliability properties.

  text: Ultrasonic wire bonding is a common technology for connecting electrodes of
    electronic components like power modules. Nowadays, bond connections are often
    made of copper instead of aluminum due to its thermal and mechanical assets. One
    of the main cost factors in the wire bonding process is the acquisition cost of
    consumables such as bonding tools. For copper wire bonding tool lifetime is much
    lower than for aluminium bonding. This paper presents a micro wear model for wedge/wedge
    bonding tools that was validated by observing wear patterns with a scanning electron
    microscope. The wear coefficient is determined in long-term bonding tests. The
    application of Fleischer´s wear approach incorporating frictional power to a finite
    element simulation of the bonding processes is used to shift element nodes depending
    on the rising frictional power for finite element modeling. The presented simulation
    method can be used to take tool wear into consideration for creating tools with
    increased lifetime. This enables the production of reliable bond connections using
    heavy as well as thin wire of any material. The paper discusses the predominant
    influences of wear on the main tool functions and their changes over tool life.
    Furthermore, the influence of the tool groove angle on the tool wear was investigated.
    One of the main results is that the wear is largest during the last phase of each
    bonding process, when the contact area between tool and wire is largest.

  text: Redundancy is a common approach to improve system reliability, availability
    and safety in technical systems. It is achieved by adding functionally equivalent
    elements that enable the system to remain operational even though one or more
    of those elements fail. This paper begins with an overview on the various terminologies
    and methods for redundancy concepts that can be modeled sufficiently using established
    reliability analysis methods. However, these approaches yield very complex system
    models, which limits their applicability. In current research, Bayesian Networks
    (BNs), especially Dynamic Bayesian Networks (DBNs) have been successfully used
    for reliability analysis because of their benefits in modeling complex systems
    and in representing multi-state variables. However, these approaches lack appropriate
    methods to model all commonly used redundancy concepts. To overcome this limitation,
    three different modeling approaches based on BNs and DBNs are described in this
    paper. Addressing those approaches, the benefits and limitations of BNs and DBNs
    for modeling reliability of redundant technical systems are discussed and evaluated.

  text: Tire-wheel assembly is the only connection between road and vehicle. Contacting
    directly with road within postcard size of contact area, it is mounted and guided
    by the suspension system. Therefore kinematics and compliances of suspension system
    greatly influence the frictional coupling of tire tread elements and road surface
    asperities by affecting pressure and sliding velocity distribution in the contact
    zone. This study emphasizes the development of a numerical methodology for frictional
    rolling contact analysis with focus on interaction of suspension system dynamics
    and tire-road contact using ADAMS. For this purpose a comprehensive flexible multibody
    system of the multi-link rear suspension is established, where both flexible and
    rigid bodies are modeled to allow large displacements with included elastic effects.
    To meet accuracy requirements for the high frequency applications, such as road
    excitations, the amplitude- and frequency-dependency of rubber-metal bushings
    is included. Furthermore the proposed flexible viscoelastic suspension model is
    enhanced by a Flexible Ring Tire Model (FTire), which describes a 3D tire dynamic
    response and covers any road excitations by tread submodel connected to road surface
    model. Concerning the verification and validation procedure numerous experiments
    are carried out to confirm the validity and the accuracy of both the developed
    submodels and the entire model. The devised approach makes it possible to investigate
    the influence of suspension system design on dynamical rolling contact and to
    evaluate tire tread wear. Therefore it can be a useful tool to predict frictional
    power distribution within the contact area under more realistic conditions.

  text: This paper presents a benchmark data set for condition monitoring of rolling
    bearings in combination with an extensive description of the corresponding bearing
    damage, the data set generation by experiments and results of datadriven classifications
    used as a diagnostic method. The diagnostic method uses the motor current signal
    of an electromechanical drive system for bearing diagnostic. The advantage of
    this approach in general is that no additional sensors are required, as current
    measurements can be performed in existing frequency inverters. This will help
    to reduce the cost of future condition monitoring systems. A particular novelty
    of the present approach is the monitoring of damage in external bearings which
    are installed in the drive system but outside the electric motor. Nevertheless,
    the motor current signal is used as input for the detection of the damage. Moreover,
    a wide distribution of bearing damage is considered for the benchmark data set.
    The results of the classifications show that the motor current signal can be used
    to identify and classify bearing damage within the drive system. However, the
    classification accuracy is still low compared to classifications based on vibration
    signals. Further, dependency on properties of those bearing damage that were used
    for the generation of training data are observed, because training with data of
    artificially generated and real bearing damages lead to different accuracies.
    Altogether a verified and systematically generated data set is presented and published
    online for further research

  text: Usage of copper wire bonds allows to push power boundaries imposed by aluminum
    wire bonds. Copper allows higher electrical, thermal and mechanical loads than
    aluminum, which currently is the most commonly used material in heavy wire bonding.
    This is the main driving factor for increased usage of copper in high power applications
    such as wind turbines, locomotives or electric vehicles. At the same time, usage
    of copper also increases tool wear and reduces the range of parameter values for
    a stable process, making the process more challenging. To overcome these drawbacks,
    parameter adaptation at runtime using self-optimization is desired. A self-optimizing
    system is based on system objectives that evaluate and quantify system performance.
    System parameters can be changed at runtime such that pre-selected objective values
    are reached. For adaptation of bond process parameters, model-based self-optimization
    is employed. Since it is based on a model of the system, the bond process was
    modeled. In addition to static model parameters such as wire and substrate material
    properties and vibration characteristics of transducer and tool, variable model
    inputs are process parameters. Main simulation result is bonded area in the wiresubstrate
    contact. This model is then used to find valid and optimal working points before
    operation. The working point is composed of normal force and ultrasonic voltage
    trajectories, which are usually determined experimentally. Instead, multiobjective
    optimalization is used to compute trajectories that simultaneously optimize bond
    quality, process duration, tool wear and probability of tool-substrate contacts.
    The values of these objectives are computed using the process model. At runtime,
    selection among pre-determined optimal working points is sufficient to prioritize
    individual objectives. This way, the computationally expensive process of numerically
    solving a multiobjective optimal control problem and the demanding high speed
    bonding process are separated. To evaluate to what extent the pre-defined goals
    of self-optimization are met, an offthe- shelf heavy wire bonding machine was
    modified to allow for parameter adaptation and for transmitting of measurement
    data at runtime. This data is received by an external computer system and evaluated
    to select a new working point. Then, new process parameters are sent to the modified
    bonding machine for use for subsequent bonds. With these components, a full self-optimizing
    system has been implemented.

  text: Multibody models of mechatronic systems are usually interdisciplinary and
    are continuously gaining complexity, due to a growing demand for comprehensive
    models of systems including effects of electro mechanics, elastic bodies, contacts
    and friction. To be capable of simulating large models with subassemblies and
    contact between bodies, reduction techniques are required, which need certain
    experience in the choice of parameters. This publication discusses different possibilities
    for the modal description of structures in flexible multibody models with application
    to an Adaptive Frontlighting System in ADAMS. It will be shown that mode count,
    assembling of structures before and after modal reduction and influence of damping
    parameters of particular structures and subassemblies affect the behavior of the
    entire system. A common reduction technique for flexible structures in multibody
    models is the component mode synthesis, which uses a certain number of modes for
    description of the modal behavior of a structure. The influence of the mode count
    will be shown by means of different modal descriptions of one structure that contributes
    to a comprehensive model. Another study will prove that modal data of subassemblies
    and assemblies of modal reduced single structures lead to different models. The
    definition of damping parameters depends on the number of structures that have
    been added to an assembly before modal reduction and on the number of modal reduced
    structures. The comparison of subassemblies and the entire model to experimental
    data will highlight the accuracy, computational overhead, complexity of models
    and modeling efficiency of the comprehensive model for the frontlighting system.

  text: To increase quality and reliability of copper wire bonds, self-optimization
    is a promising technique. For the implementation of self-optimization for ultrasonic
    heavy copper wire bonding machines, a model of stick-slip motion between tool
    and wire and between wire and substrate during the bonding process is essential.
    Investigations confirm that both of these contacts do indeed show stick-slip movement
    in each period oscillation. In a first step, this paper shows the importance of
    modeling the stick-slip effect by determining, monitoring and analyzing amplitudes
    and phase angles of tooltip, wire and substrate experimentally during bonding
    via laser measurements. In a second step, the paper presents a dynamic model which
    has been parameterized using an iterative numerical parameter identification method.
    This model includes Archard’s wear approach in order to compute the lost volume
    of tool tip due to wear over the entire process time. A validation of the model
    by comparing measured and calculated amplitudes of tool tip and wire reveals high
    model quality. Then it is then possible to calculate the lifetime of the tool
    for different process parameters, i.e. values of normal force and ultrasonic voltage.
