text: In many branches in the designengineerdepartment, product designs are just
variations of existing parts. To bring the additive manufacturing technology closer
to the Designer, it is necessary to show them which of their existing, conventionally
manufactured parts can be produced with this technology. Apartselection methodology
supportsdesigners in the decision whether a part is suitable for additive manufacturingor
not. Due to the potential of the technology, which was especially seen in the
aerospace industries, many criteria of the methodology were initially adapted
for this industry. Furthermore the methodology is based on a quantified weighting
system, which comes to a certain subjectivity. For future use, a development towards
a less subjective methodology should be accomplished. Through a more detailed
adaption for individual industries and a simplification of the input mode, the
objectivity of the criteria can be increased. Likewise, the input time can be
reduced by simplifying the questioning. A more efficient part selection will be
achieved by a better weighting system.In the BMBF project “OptiAMix” this methodology
is supposed to be further developed for highly different branches. By a better
weighting system, the part selection will be more efficient. Therefore,the willingness
for the use of the improved selection andfor the additive manufacturing technology
will be increased.

text: Although infringements of intellectual properties in terms of product piracy
are growing for years and threaten investments in research and development most
companies still rely on legal measures like property rights. A more preventive
effect to protect against counterfeits can be achieved using technical measures
complicating reverse engineering, improving traceability and assuring data protection.
Additive Manufacturing can contribute a lot to the effectivity and efficiency
of those technical measures but presently they are often unconsidered during product
development. To support decision makers and designers through all the steps of
a product development process an integrated systematic approach has been developed.
Protective measures using AM are allocated to specific process steps and responsible
persons in charge so that the result is a guideline for “design for protection”.
The main idea is to help developing piracy-robust products for that the return
of investment is not threatened by counterfeits and its economical impacts.

text: In conventional manufacturing, ramp-up-management describes the planning and
organization of the period between finished product development and the achievement
of full production capacity for defined products. This classification has to be
adapted and restructured by means of product independent and tool-free production
in additive manufacturing. Therefore ramp-up-management already starts with decisions
on the extentof the use of additive manufacturing, includes the building of technology-know-how
as well as the technology integration into processes and infrastructure of the
company and ends with the attainment of a sufficient process reliability for the
AM-machine. This paper focuses on technology integration in processes and infrastructure,
which is part of the German research project OptiAMix. In this project, new systems
for process state analysis adapted to additive manufacturing and methods for the
optimal integration of additive manufacturing are developed. Furthermore ways
of using the synergies of existing infrastructures and new innovative production
technologies are determined.

text: Designing parts for additive manufacturing (AM) offers a broad range of geometrical
and functional potentials. On the one hand the manufacturingtechnology offers
the possibility of manufacturing highly complex freeform shapes, often referred
to as bionic shapes. By use of these, perfect force fluxes without stress risings
due to imperfect notches are realizable, getting the most value of used material.
On the other hand these complex structures require a reliable geometry representation
in compatible CAD-files. Conventional CAD systems were developed to generate geometries
that are manufacturable with conventional machining. These are not capable of
representing the high complex designs for AM. Especially for geometries generated
by CAE like from topology optimization the conventional CAD systems fail to take
advantage of the combination of CAE and AM. This paper explains why there is a
lack of compatibility of well-known CAD systems with the potentials of AM. Therefore
the AM-side of the problem is described by showing some potentials of AM and the
need of high complex structures for this manufacturing technology. For the other
side of the problem conventional methodologies for geometry representation of
CAD systems are described and their limitations with regard to AM are worked out.
Finally a voxel based geometry representation is presented as a solution for computer
aided geometry generation of high complex AM–structures.

text: Even in times where additive manufacturing has a peak in media and industry
interest, only few companies have already implemented this technology. Many companies
struggle with the use of AM even if they have already identified the benefits
of this technology for their business. Additional knowledge along the whole product
development chain is necessary to succeed in implementing this technology. As
all other production technologies, AM has certain strength and weaknesses which
affect the suitable part candidates. Redesign or manufacturing approaches of unsuited
part candidates are no very likely to be successful. In general, aspects like
design rules need to be known along the product development process in order to
achieve technology-based benefits during production and post-processing resulting
in economic success. This paper will present a holistic approach which will assist
the designer during product development and manufacturing based on an example
part from the space industry. Then methodology starts with an appropriate part
selection as a key parameter for the product development process. Based on the
promising part candidates, deductions for the further product development process
will be described. This includes approaches for functional integration as well
as a methodology for the compilation of part requirements. Those are utilized
for a black box methodology, ensuring a time-efficient redesign based on FEA optimization
and design rules for additive manufacturing. Best practices for integrating (or
in the best case avoiding) traditional technologies are discussed. Based on this,
the development of industrialization and test and verification plans for production
are shown. This includes the marking of parts for traceability during the whole
product lifecycle for quality reasons as well as for product protection. Furthermore,
production and production planning are discussed. This is followed by post-processing
and testing procedures of the part. The paper will close with a detailed economic
view on the topic and some deductions regarding the changes in the supply chain.
The methodology itself is discussed and explained on a real sample metal part.
The general methodology is discussed on the basis of the space industry but is
subject to be adapted to other industries.

text: Fused Deposition Modeling (FDM) is used for prototypes, single-partproduction
and small batch productions of thermoplastic components. This manufacturing technique
has the huge benefit that no forming tool is needed. The knowledge about dimensional
deviations which occur in the FDM process is necessary for calculating fits and
for determining tolerances. A major challenge is the reproducibility of the dimensional
accuracy of FDM parts and the reproducibility between different FDM machines.
There are many influential factors on the dimensional accuracy in the FDM process
for example geometric, material-specific or process-specific factors, which are
considered in this paper. The influence of the part position on the build platform
of a Stratasys Fortus 400mc is analyzed in terms of the achievable dimensional
accuracy. For this purpose, the temperature distribution in the actively heated
build chamber is investigated and possible correlations to the dimensional accuracy
are identified. The reproducibility of one machine is examined by a multiple production
of the test specimens. In addition, a comparison with three other FDM machines
from Stratasys is made. Afterwards, the long-term reproducibility of the dimensional
accuracy is verified to consider how environmental influences such as maintenance
or modification of machine components affect the dimensional accuracy of the FDM
process.

text: Compared to conventional polymer processing technologies the material selection
in the Fused Deposition Modelling (FDM) process is restricted. To expand the range
of materials the requirements for the material properties and the semi-finished
products (filaments) must be clarified. For this, a machine- and process-independent
rating of the processability is necessary. The established standards for the tensile
strength test apply to specimens with nearly isotropic mechanical properties.
The FDM process generates anisotropic parts. The properties are mainly influenced
by the machine quality and the data processing. It is not possible to test a material
for FDM independently of the machine and the data processing. In this paper, machine
and process specific influences are investigated. Considering these influences,
a custom-built specimen is created to test the tensile strength of the welding
seams for polyamide 6. This procedure allows a machine- and process-independent
rating of the processability in terms of tensile strength for different materials.

text: A widely used Additive Manufacturing (AM) technology is Fused Deposition Modeling
(FDM) to create prototypes and end-use parts with close-to-production thermoplastics.
For their use as a final product, it is necessary that additively manufactured
parts strictly adhere to the geometrical requirements of the technical drawing.
In this paper, the holes and cylinders of the cylindrical elements are investigated
in terms of achievable geometrical accuracy. For this purpose, different test
specimens that allow a measurement of inner and outer diameters from 3 to 80 mm
were designed. All specimens were measured with a coordinate measuring machine
(CMM) to evaluate deviations from the nominal dimension and form deviations. The
measuring method includes a scanning of the surface to record the course of dimensional
deviations over the diameter. Thus, it was possible to visualize how deviations
on cylindrical elements manufactured in FDM occur. In order to counteract these
deviations and to improve the dimensional accuracy, different shrink factors and
filling patterns were investigated. Consequently, an improvement of the dimensional
accuracy was achieved.

text: 'In order to improve the credibility of modern simulation tools, uncertainties
of different kinds have to be considered. This work is focused on epistemic uncertainties
in the framework of continuum mechanics, which are taken into account by fuzzy
analysis. The underlying min-max optimization problem of the extension principle
is approximated by α-discretization, resulting in a separation of minimum and
maximum problems. To become more universal, so-called quantities of interest are
employed, which allow a general formulation for the target problem of interest.
In this way, the relation to parameter identification problems based on least-squares
functions is highlighted. The solutions of the related optimization problems with
simple constraints are obtained with a gradient-based scheme, which is derived
from a sensitvity analysis for the target problem by means of a variational formulation.
Two numerical examples for the fuzzy analysis of material parameters are concerned
with a necking problem at large strain elastoplasticity and a perforated strip
at large strain hyperelasticity to demonstrate the versatility of the proposed
variational formulation. '

text: Zuverlässigkeit, Sicherheit und Verfügbarkeit gewinnen bei der Anwendung von
technischen Systemen eine immer größere Bedeutung. Aus diesem Grund hat sich Condition
Monitoring, die Zustandsüberwachung eines technischen Produkts, in verschiedenen
Industriebranchen etabliert. Die sensorbasierte Überwachung eines Produkts während
seiner Betriebsdauer in Kombination mit Condition Monitoring Methoden ermöglichen
die Bestimmung des aktuellen Zustands des Produkts und somit eine Diagnose, ob
das Produkt seine ihm zugeschriebene Funktion zum aktuellen Zeitpunkt erfüllt.
Neben Diagnosen bietet Condition Monitoring auch die Möglichkeit Prognosen aufzustellen,
dabei wird die restliche Nutzungsdauer des Produkts aufbauend auf geeigneten Sensordaten
geschätzt. So kann eine intelligente Wartungsplanung umgesetzt werden, die im
Gegensatz zu klassischen Ansätzen keine festen Wartungsintervalle benötigt und
die Nachteile einer rein reaktiven Wartung kompensiert. Stattdessen ist es möglich
ein Element bis vor das Ende seiner Lebensdauer zu nutzen und erst dann zu warten,
um eine optimale Nutzung zu gewährleisten. Durch eine Bestimmung der verbleibenden
Restlebensdauer während des Betriebs ist eine optimale Wartungsplanung möglich,
wodurch die Verfügbarkeit und die Auslastung der überwachten Produkte signifikant
gesteigert werden kann. In dieser Arbeit soll ein produktspezifisches Condition
Monitoring System für Gummi-Metall-Elemente entwickelt werden. Diese Elemente
werden zur Federung, Geräusch- und/oder Schwingungsisolation in vielen verschiedenen
Anwendungen eingesetzt, wie bspw. in Nutz- und Schienenfahrzeugen oder Windenergieanlagen.
In Industrie und Forschung werden bereits Zustandsüberwachungen von Systemen mit
integrierten Gummi-Metall-Elementen eingesetzt, allerdings noch keine Condition
Monitoring Systeme zur alleinigen Zustandsüberwachung dieser Elemente. Aktuell
ist es üblich die Lebensdauer dieser Elemente aufbauend auf beschleunigten Lebensdauerversuchen
und Erfahrungswerten abzuschätzen. Mit dem Ziel die Lebensdauer des fokussierten
Produkts präziser vorherzusagen und damit eine intelligente Wartungsplanung zu
ermöglichen, wird die Entwicklung eines Condition Monitoring Systems für Gummi-Metall-Elemente
angestrebt und in dieser Arbeit erläutert.

text: In vielen verschiedenen Industriezweigen hat sich Condition Monitoring aufgrund
seiner finanziellen und sicherheitstechnischen Vorteile bereits etabliert. Um
die Verlässlichkeit und die Auslastung zu steigern, sowie um die Lebenszykluskosten
zu reduzieren, steigt auch im Schienenfahrzeugbereich die Anzahl an eingesetzten
Condition Monitoring Systemen. Studien zu Versagensmodi von Schienenfahrzeugen
haben gezeigt, dass Versagensursachen meistens in den Radprofilen oder im Fahrwerk
liegen [1]. Wird das Fahrwerk heute mittels Condition Monitoring überwacht, werden
hierfür häufig Sensoren an den Wagons angebracht, um bspw. deren Schwingungen
zu kontrollieren [2, 3]. In dieser Arbeit liegt der Fokus auf Gummi-Metall-Elementen
(GM-Elementen) der Jörn GmbH.; als elastische Lager im Drehgestell sind diese
Teil des Fahrwerks eines Schienenfahrzeugs. Mit dem Ziel die Wartungsplanung dieser
Elemente zu optimieren, ist untersucht worden, ob diese Elemente einzeln mittels
Condition Monitoring überwacht werden können. Die hierfür durchgeführten beschleunigten
Lebensdauertests werden im nächsten Abschnitt erläutert. Anschließend werden die
modellbasierten Methoden dargestellt, die aufbauend auf den im Versuch aufgezeichneten
Daten eine Prognose der nutzbaren Restlebensdauer (RUL, remaining useful lifetime)
der GM-Elemente aufstellen. Im letzten Abschnitt folgen eine kurze Zusammenfassung
und ein Ausblick.

text: 'In der Windenergieindustrie haben die Größen Zuverlässigkeit, Sicherheit
und Verfügbarkeit eine enorme Bedeutung erlangt aufgrund des Trends Windenergieanlagen
zur optimalen Windausnutzung an schwer zugänglichen Positionen aufzustellen, wie
bspw. Offshore. Dies führt zu erschwerten Wartungsbedingungen und damit zu höheren
Kosten. Der Einsatz von Condition Monitoring hat sich in dieser Industrie etabliert,
denn diese Technik ermöglicht eine Zustandsdiagnose des überwachten Systems und
eine Prognose seiner nutzbaren Restlebensdauer (remaining useful life: RUL), jeweils
basierend auf geeigneten Sensordaten. In dieser Arbeit wird ein Konzept für ein
produktspezifisches Condition-Monitoring-System für Gummi-Metall-Elemente (GM-Elemente)
vorgestellt, welches den Schwerpunkt auf die Prognose der RUL dieser Elemente
setzt. In Windenergieanlagen werden zahlreiche GM-Elemente zur Geräusch- und Schwingungsisolation
verwendet. Der Einsatz des hier vorgestellten produktspezifischen Condition-Monitoring-Systems
kann somit einen erheblichen Beitrag zum verlässlichen Betrieb von Windenergieanlagen
liefern, da die Überwachung einzelner Komponenten in die Zustandsüberwachung der
gesamten Anlage integriert und dadurch der Betrieb der Anlage optimiert werden
kann. In dieser Arbeit werden einige Herausforderungen diskutiert, die sich bei
der Entwicklung eines Condition-Monitoring-Systems für GM-Elemente ergeben. So
wird evaluiert, welche Größen sich zur Beschreibung der Alterung eines spezifischen
Elements eignen und wie diese gemessen werden können. Temperaturen werden bereits
in einigen technischen Systemen, wie auch in Windenergieanlagen, aufgezeichnet
und ausgewertet, aber ihr Potential für die Bestimmung der RUL der überwachten
Komponente ist noch nicht ausgeschöpft. Hier wird eine Lösungsmöglichkeit vorgestellt,
die auf Temperatursensoren aufbaut. Als Grundlage für die Entwicklung des Condition-Monitoring-Systems
wurden beschleunigte Lebensdauerversuche der GM-Elemente auf einem Versuchsstand
zur Schwingungsanalyse durchgeführt. In diesen Lebensdauerversuchen wird die mechanische
Alterung eines GM-Elements über einen kraftgeregelten Hydraulikzylinder erzielt.
Dabei wird das Ende der Lebensdauerversuche in einem ersten Schritt über die Wegamplitude
des Zylinders bestimmt. Während dieser Versuche wurden diverse Sensoren eingesetzt.
Die aufgezeichneten Temperaturdaten zeigen, dass sich Temperaturmessungen eignen
die Lebensdauer von GM-Elementen mittels Condition Monitoring Prognosemethoden
zu schätzen.'

text: The transportation of dry fine powders is an emerging technologic task, as
in biotechnology, pharmaceu-tical and coatings industry the particle sizes of
processed powders get smaller and smaller. Fine powdersare primarily defined by
the fact that adhesive and cohesive forces outweigh the weight forces, leadingto
mostly unwanted agglomeration (clumping) and adhesion to surfaces. Thereby it
gets more difficult touse conventional conveyor systems (e.g. pneumatic or vibratory
conveyors) for transport. A rather newmethod for transporting these fine powders
is based on ultrasonic vibrations, which are used to reducefriction between powder
and substrate. Within this contribution an experimental set-up consisting of apipe,
a solenoid actuator for axial vibration and an annular piezoelectric actuator
for the high frequencyradial vibration of the pipe is described. Since amplitudes
of the radial pipe vibration should be as large aspossible to get high effects
of friction reduction, the pipe is excited to vibrate in resonance. To determinethe
optimum excitation frequency and actuator position the vibration modes and resonance
frequenciesof the pipe are calculated and measured. Results are in good accordance.

text: In power electronics, copper connector pins are e.g. used to connect control
boards with power modules. The new chip generation based on SiC and GaN technology
increase the power density of semiconductor modules significantly with junction
temperatures reaching 200°C. To enable reliable operation at such high temperature,
the soldering of these connector pins should be substituted by a multi-dimensional
copper-copper bonding technology. A copper pin welded directly on DBC substrate
also simplifies the assembly. With this aim, a proper bond tool and a suitable
connector pin geometry are designed. This paper presents a two-dimensional trajectory
approach for ultrasonic bonding of copper pieces, e.g. connector pins, with the
intention to minimize mechanical stresses exposed to the substrate. This is achieved
using a multi-dimensional vibration system with multiple transducers known from
flip chip bonding. Applying a planar relative motion between the bonding piece
and the substrate increases the induced frictional power compared to one-dimensional
excitation. The core of this work is the development of a new tool design which
enables a reliable and effective transmission of the multidimensional vibration
into the contact area between nail-shaped bonding piece and substrate. For this
purpose, different bonding tool as well as bonding piece designs are discussed.
A proper bonding tool design is selected based on the simulated alternatives.
This tool is examined in bonding experiments and the results are presented. In
addition, different grades of hardness for bonding piece and substrate are examined
as well as different bonding parameters. Optical inspection of the bonded area
shows the emergence of initial micro welds in form of a ring which is growing
in direction of the interface boundaries with increasing bonding duration.

text: The integrated modeling of behavior and reliability in system development
delivers a model-based approach for reliability investigation by taking into account
the dynamic system behavior as well as the system architecture at different phases
of the development process. This approach features an automated synthesis of a
reliability model out of a behavior model enabling for the closed loop modeling
of degradation of the system and its (dynamic) behavior. The approach is integrated
into the development process following Systems Engineering. It is based on standard
models used in model-based development methodologies i.e. SysML or Matlab/Simulink.
In addition to the theoretical description of the necessary steps the procedure
is validated by an application example at two stages of the development process.

text: Piezoelectric inertia motors also known as stick-slip motors or (smooth) impact
drives use the inertia of a body to drive it in small steps by means of an uninterrupted
friction contact. In addition to the typical advantages of piezoelectric motors,
they are especially suited for miniaturisation due to their simple structure and
inherent fine-positioning capability. Originally developed for positioning in
microscopy in the 1980s, they have nowadays also found application in mass-produced
consumer goods. Recent research results are likely to enable more applications
of piezoelectric inertia motors in the future. This contribution gives a critical
overview of their historical development, functional principles, and related terminology.
The most relevant aspects regarding their design i.e., friction contact, solid
state actuator, and electrical excitation are discussed, including aspects of
control and simulation. The article closes with an outlook on possible future
developments and research perspectives.
