text: Theimplementation of additive manufacturing as an industrial manufacturing
process poses extraordinary challenges to companies due to their far-reaching
differences to conventional processes. In addition to the major differences in
the production process, the pre and post process steps in particular also require
a rethinking for companies and their employees. To overcome these challenges and
specifically to assist SMEs in the integration of technologies five industrial
companies are researching together within research project "OptiAMix", funded
by the German Federal Ministry of Education and Research (BMBF) and coordinated
by the Paderborn University. This paper focuses on the development of an optimal
and standardized process chain and its implementation in a general integration
methodology. This enables the standardized integration of additivemanufacturing
in order to create a uniform understanding of the procedures and tasks within
the company for the industrial application of additive manufacturing at an early
stage as well as the full exploitation of its high potentials. Therefore, the
methodology also includes other technology-specific components such as strategic
component selection, decision support for "make or buy" and the implementation
of automated component marking.

text: By adding fibers to a polymer matrix, a reinforcement of the material can
be achieved. Short fiber-reinforced polymers can easily be processed by the Fused
Deposition Modeling (FDM) process without major modifications to the processing
machine. For instance,short fiber-reinforced filaments can be processed to produce
short fiber-reinforced components in the FDM process. In many other additive manufacturing
processes this is not possible at this low cost. The choice of the matrix material,
fiber type, fiber length and fiber orientation have a major influence on the properties
of the produced component. In this paper, short fiber-reinforced filaments are
processed by the FDM process. The processing properties and the resulting part
properties are investigated with regard to fiber-specific influences. Additionally,
the effects of different strand geometries and thus changed flow fields on the
fiber orientation and mechanical part properties are investigated.

text: Bainite is a steel microstructure consisting of three phases, bainitic ferrite,
austenite and carbides. It forms in two different morphologies, upper and lower
bainite, where different diffusion mechanisms are dominant. The aim of this work
is to simulate both transformations within a unified model. To this end, we extend
an own previously published model for lower bainite with diffusion across the
phase interface. As a central idea we introduce weighted Helmholtz energy functions
and a weighted mobility tensor, respectively. The individual Helmholtz energy
functions and mobility terms are related to the different diffusion mechanisms
which are responsible for the formation of both morphologies. Two representative
examples illustrate the capability of the coupled phase field/diffusion model
and show the expected behaviour.

text: Rubber-metal-elements are used in a wide range of applications for vibration
and sound isola- tion. Nowadays it is state of the art to calculate the lifetimes
of these elements under mechanical stress prior to their service life. To establish
more reliable and safer rubber-metal-elements, continuous monitoring by dif- ferent
sensors can be used. Especially prognostics enable a rise in reliability, availability
and safety. To estab- lish these advantages, estimating the remaining useful lifetime
of rubber-metal-elements should be realized during its service life based on current
information on its condition. Therefore a suitable measure to monitor the condition
of the element is necessary. This work focuses on temperature signals. This approach
allows in- cluding the ambient temperature and thereby involving changing operating
conditions. For estimating the RUL of rubber-metal-elements a model-based prognostics
approach based on particle filtering is proposed. Its performance is analyzed
regarding relevant parameters to enable the best performance for the applied data.

text: The handling of fine powders is an important task in modern production processes.
However, as fine powders strongly tend to adhesion and agglomeration, their processing
with conventional methods is difficult or impossible. Especially when processing
small amounts of highly sensitive fine powders, conventional methods reach their
technical limits. In process steps such as dosing, transport, and especially mixing
of fine powders new methods are required. Apart from the well-known method of
manipulating powder properties by adding chemical additives, this contribution
aims at improving the handling of dry fine powders by using vibrations at different
frequencies. Modules are presented, which enable the continuous dosing, the homogeneous
mixing and the transport of dry fine powders. Finally, these modules are combined
for the production of a homogeneous mixture of two dry fine powders.

text: Abstract:Since fine powders tend strongly to adhesion and agglomeration, their
processing withconventional methods is difficult or impossible. Typically, in order
to enable the handling of finepowders, chemicals are added to increase the flowability
and reduce adhesion. This contributionshows that instead of additives also vibrations
can be used to increase the flowability, to reduceadhesion and cohesion, and thus
to enable or improve processes such as precision dosing, mixing,and transport
of very fine powders. The methods for manipulating powder properties are describedin
detail and prototypes for experimental studies are presented. It is shown that
the handling of finepowders can be improved by using low-frequency, high-frequency
or a combination of low- andhigh-frequency vibration.

text: State-of-the-art industrial compact high power electronic packages require
copper-copper interconnections with larger cross sections made by ultrasonic bonding.
In comparison to aluminium-copper, copper-copper interconnections require increased
normal forces and ultrasonic power, which might lead to substrate damage due to
increased mechanical stresses. One option to raise friction energy without increasing
vibration amplitude between wire and substrate or bonding force is the use of
two-dimensional vibration. The first part of this contribution reports on the
development of a novel bonding system that executes two-dimensional vibrations
of a tool-tip to bond a nail- like pin onto a copper substrate. Since intermetallic
bonds only form properly when surfaces are clean, oxide free and activated, the
geometries of tool-tip and pin were optimised using finite element analysis. To
maximize the area of the bonded annulus the distribution of normal pressure was
optimized by varying the convexity of the bottom side of the pin. Second, a statistical
model obtained from an experimental parameter study shows the influence of different
bonding parameters on the bond result. To find bonding parameters with the minimum
number of tests, the experiments have been planned using a D-optimal experimental
design approach.

text: Ultrasonic bonding and welding are common friction based approaches in the
assembly of power electronics. Interconnections with cross-sections of 0.3 mm²
up to 12 mm² made from copper are well suited in high power applications. For
increasing friction energy, which is responsible for bond formation, a two-dimensional
vibration approach is applied to newly developed interconnection pins. Using two-dimensional
vibration for bonding requires identification of suitable bonding parameters.
Even though simulation models of wire bonding processes exist, parameters for
the two-dimensional pin-bonding process cannot be derived accurately yet. Within
this contribution, a methodology and workflow for experimental studies identifying
a suitable bond parameter space are presented. The results of a pre-study are
used to set up an extensive statistical parameter study, which gives insights
about the bond strength change due to bond process parameter variation. By evaluation
of electrical data captured during bonding, errors biasing the resulting shear
forces are identified. All data obtained during the experimental study is used
to build a statistical regression model suitable for predicting shear forces.
The accuracy of the regression model’s predictions is determined and the applicability
to predict process parameters or validate simulation models is assessed. Finally,
the influence of the tool trajectory on the bond formation is determined, comparing
one dimensional, elliptic and circular trajectories.

text: Selbstoptimierung bietet die Möglichkeit der autonomen Anpassung des Systemverhaltens
an veränderliche Ziele. Dabei ist vor allem der Aspekt Zuverlässigkeit von maßgeblicher
Bedeutung, da über einen an die aktuelle Systemzuverlässigkeit angepassten Betriebspunkt
die Leistungsfähigkeit verbessert wird, während das Ausfallverhalten besser vorhersehbar
wird. Zur Anpassung des Systemverhaltens an die aktuelle Zuverlässigkeit mittels
Selbstoptimierung müssen die ersten beiden Schritte des Selbstoptimierungsprozesses
unterstützt werden. Für die Analyse der Ist-Situation ist eine Erkennung des aktuellen
Degradationszustands mittels Condition Monitoring notwendig. Zur Auswahl geeigneter
Verfahren werden bestehende Ansätze hinsichtlich ihrer Eignung klassifiziert.
Der zweite Schritt, die Bestimmung der Systemziele, wird durch eine strukturierte
Methode zum Finden verlässlichkeitsrelevanter Zielfunktionen ergänzt. Dabei werden
kritische Komponenten identifiziert, Optimierungsparameter festgelegt und die
Verlässlichkeit in Abhängigkeit des Systemverhaltens quantifiziert. Entwickler
selbstoptimierender Systeme werden somit durch geeignete Mittel bei der Implementierung
beider Schritte unterstützt. Abschließend wird der praktische Einsatz der vorgestellten
Methoden anhand zweier Beispiele gezeigt.
