Download or read book Component Surfaces written by Jan C. Aurich and published by Springer Nature. This book was released on 2023-10-03 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sheds new light on component surfaces and the scientific fundamentals of their creation, characterization, and application. The book also provides a new interdisciplinary perspective on the topic, studying component surfaces with a multiscale approach and linking fundamental and applied research. The book builds on the success of the coordinated research project funded by Deutsche Forschungsgemeinschaft (DFG) from 2011 – 2023: the CollaborativeResearch Center CRC 926 “Microscale Morphology of Component Surfaces (MI-COS)”, in which, over the years, 100+ researchers have co-operated at the University of Kaiserslautern, Germany, and affiliated institutes, yielding 500+ scientific papers in journals from different fields of science and engineering. Divided into 2 main parts, the book starts with an introduction to the concept of Manufacturing-Morphology-Property (MMP) Relationships and dives into the fundamentals and technologies, including topics such as the geometrical, microstructural, and chemical characterization, indentation, and scratching on the nanoscale, micro milling and micro grinding, cryogenic machining, cold spraying, and additive manufacturing. In the first part, readers discover more about the interactions between particles and surfaces, the interrelationship of manufacturing, surface morphology and properties of titanium, the influence of manufacturing and load conditions on the phase transformation and fatigue of austenitic stainless steels, and the influence of surface morphology on fatigue and tribological behavior of Transformation-Induced-Plasticity (TRIP)/Twinning-Induced Plasticity (TWIP) Steels. The second part of this book is devoted to the applications of component surfaces, covering topics like the manufacturing of areal material measures, MMP relationships for rotating shaft sealing systems, the influence of the surface morphology on rolling bearing life under mixed lubrication, MMP relationships for chain joints, and MMP for biofilms. Scientists and engineers who deal with the influence of surfaces on macroscopic properties of components and who are interested in designing and manufacturing these surfaces to obtain desired component properties will understand the appeal of this work. Given its interdisciplinary breadth, the book also appeals to scholars and professionals in the fields of mechanical engineering, process engineering, and physics.

Download or read book Precision Metal Additive Manufacturing written by Richard Leach and published by CRC Press. This book was released on 2020-09-21 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design. Richard Leach is a professor in metrology at the University of Nottingham and heads up the Manufacturing Metrology Team. Prior to this position, he was at the National Physical Laboratory from 1990 to 2014. His primary love is instrument building, from concept to final installation, and his current interests are the dimensional measurement of precision and additive manufactured structures. His research themes include the measurement of surface topography, the development of methods for measuring 3D structures, the development of methods for controlling large surfaces to high resolution in industrial applications and the traceability of X-ray computed tomography. He is a leader of several professional societies and a visiting professor at Loughborough University and the Harbin Institute of Technology. Simone Carmignato is a professor in manufacturing engineering at the University of Padua. His main research activities are in the areas of precision manufacturing, dimensional metrology and industrial computed tomography.

Download or read book Tribology and Mechanics of Magnetic Storage Devices written by Bharat Bhushan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1035 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic recording is presently a $50 billion industry. It spans audio, video, and digi tal applications in the form of tapes and disks. The industry is expected to grow by a factor of five or more in the next decade. This growth will be accompanied by dramatic improvements in the technology, and the potential exists for magnetic-recording den sities to improve by at least one order of magnitude! Magnetic-recording process is accomplished by relative motion between a mag netic head and a magnetic medium. Types of magnetic media for digital recording are: flexible media (tapes and floppy disks) and rigid disks. Physical contact between head and medium occurs during starts and stops and hydrodynamic air film develops at high speeds. Hying heights (mean separation between head and medium) are on the order of 0. 1 micrometer comparable to surface roughness of the mating members. Need for higher and higher recording densities requires that surfaces be as smooth as possible and flying heights be as low as possible. Smoother surfaces lead to increased static/ kinetic friction and wear. In the case of magnetic tapes, in order to have high bit capac ity for a given size of a spool, we like to use as thin a tape substrate as possible. Thinner tapes are prone to local or bulk viscoelastic deformation during storage. This may lead to variations in head-tape separations resulting in problems in data reliability.

Download or read book Geometry of Surfaces written by Stephen P. Radzevich and published by Springer. This book was released on 2019-08-14 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This updated and expanded edition presents a highly accurate specification for part surface machining. Precise specification reduces the cost of this widely used industrial operation as accurately specified and machined part surfaces do not need to undergo costly final finishing. Dr. Radzevich describes techniques in this volume based primarily on classical differential geometry of surfaces. He then transitions from differential geometry of surfaces to engineering geometry of surfaces, and examines how part surfaces are either machined themselves, or are produced by tools with surfaces that are precisely machined. The book goes on to explain specific methods, such as derivation of planar characteristic curves based on Plücker conoid constructed at a point of the part surface, and that analytical description of part surface is vital for surfaces machined using CNC technology, and especially so for multi-axes NC machines. Providing readers with a powerful tool for analytical description of part surfaces machined on conventional machine tools and numerically controlled machines, this book maximizes understanding on optimal treatment of part surfaces to meet the requirements of today’s high tech industry.

Download or read book Fundamentals of Tribology and Bridging the Gap Between the Macro and Micro Nanoscales written by Bharat Bhushan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 961 pages. Available in PDF, EPUB and Kindle. Book excerpt: The word tribology was fIrst reported in a landmark report by P. Jost in 1966 (Lubrication (Tribology)--A Report on the Present Position and Industry's Needs, Department of Education and Science, HMSO, London). Tribology is the science and technology of two interacting surfaces in relative motion and of related subjects and practices. The popular equivalent is friction, wear and lubrication. The economic impact of the better understanding of tribology of two interacting surfaces in relative motion is known to be immense. Losses resulting from ignorance of tribology amount in the United States alone to about 6 percent of its GNP or about $200 billion dollars per year (1966), and approximately one-third of the world's energy resources in present' use, appear as friction in one form or another. A fundamental understanding of the tribology of the head-medium interface in magnetic recording is crucial to the future growth of the $100 billion per year information storage industry. In the emerging microelectromechanical systems (MEMS) industry, tribology is also recognized as a limiting technology. The advent of new scanning probe microscopy (SPM) techniques (starting with the invention of the scanning tunneling microscope in 1981) to measure surface topography, adhesion, friction, wear, lubricant-fIlm thickness, mechanical properties all on a micro to nanometer scale, and to image lubricant molecules and the availability of supercomputers to conduct atomic-scale simulations has led to the development of a new fIeld referred to as Microtribology, Nanotribology, or Molecular Tribology (see B. Bhushan, J. N. Israelachvili and U.
