The fuel consumption of a modern combustion engine is one of the
most important purchase criteria in contemporary society.
Increasing oil prices and exhaust emissions taxes force the
automotive industry to continuously improve the vehicle engines.
The fuel consumption is closely related to the frictional losses of
an engine. New material pairings or constructive modifications of
the piston group can reduce such losses. Another innovative concept
to lower the frictional forces is the micro-structuring of
thermo-mechanically highly stressed surfaces. Within an
interdisciplinary research group sponsored by the German Research
Foundation, scientists at the Leibniz Universität Hannover and
Universität Kassel have been working together to investigate this
research topic. This final report presents their findings and
offers scope for further discussion.
This contributed volume contains the research results presented at
the 4th Machining Innovations Conference, Hannover, September 2013.
The topic of the conference are new production technologies in
aerospace industry and the focus is on energy efficient machine
tools as well as sustainable process planning. The target audience
primarily comprises researchers and experts in the field but the
book may also be beneficial for graduate students.
Manufacturing is the basic industrial activity generating real
value. Cutting and abrasive technologies are the backbone of
precision production in machine, automotive and aircraft building
as well as of production of consumer goods. We present the
knowledge of modern manufacturing in these technologies on the
basis of scientific research. The theory of cutting and abrasive
processes and the knowledge about their application in industrial
practice are a prerequisite for the studies of manufacturing
science and an important part of the curriculum of the master study
in German mechanical engineering. The basis of this book is our
lecture "Basics of cutting and abrasive processes" (4 semester
hours/3 credit hours) at the Leibniz University Hannover, which we
offer to the diploma and master students specializing in
manufacturing science.
This contributed volume collects the scientific results of the DFG
Priority Program 1180 Prediction and Manipulation of the
Interactions between Structures and Processes. The research program
has been conducted during the years 2005 and 2011, whereas the
primary goal was the analysis of the interactions between processes
and structures in modern production facilities. This book presents
the findings of the 20 interdisciplinary subprojects, focusing on
different manufacturing processes such as high performance milling,
tool grinding or metal forming. It contains experimental
investigations as well as mathematical modeling of production
processes and machine interactions. New experimental advancements
and novel simulation approaches are also included.

Cyber-Physical and Gentelligent Systems in Manufacturing and Life
Cycle explores the latest technologies resulting from the
integration of sensing components throughout the production supply
chain, and the resulting possibilities to improve efficiency,
flexibility, and product quality. The authors present cutting edge
research into data storage in components, communication devices,
data acquisition, as well as new industrial applications. Detailed
technical descriptions of the tools are presented in addition to
discussions of how these systems have been used, the benefits they
provide, and what industry problems they could tackle in the
future. This is essential reading for researchers and production
engineers interested in the potential of cyber physical systems to
optimize all parts of the supply chain.
The focus of this book is an application of Digital Twin as a
concept and an approach, based on the most accurate view on a
physical production system and its digital representation of
complex engineering products and systems. It describes a
methodology to create and use Digital Twin in a built environment
for the improvement and optimization of factory processes such as
factory planning, investment planning, bottleneck analysis, and
in-house material transport. The book provides a practical response
based on achievements of engineering informatics in solving
challenges related to the optimization of factory layout and
corresponding processes. This book introduces the topic, providing
a foundation of knowledge on process planning, before discussing
the acquisition of objects in a factory and the methods for object
recognition. It presents process simulation techniques, explores
challenges in process planning, and concludes by looking at future
areas of progression. By providing a holistic, trans-disciplinary
perspective, this book will showcase Digital Twin technology as
state-of-the-art both in research and practice.
