Book Description
The function of a component part can be profoundly affected by its surface topography. There are many examples in nature of surfaces that have a well-controlled topography to affect their function. Examples include the hydrophobic effect of the lotus leaf, the reduction of fluid drag due to the riblet structure of shark skin, the directional adhesion of the gecko foot and the angular sensitivity of the multi-faceted fly eye. Surface structuring is also being used extensively in modern manufacturing. In this way many properties can be altered, for example optical, tribological, biological and fluidic. Previously, single line (profile) measurements were adequate to control manufacture of surfaces, but as the need to control the functionality of surfaces increases, there is a growing need for three-dimensional (areal) measurement and characterisation techniques. For this reason there has been considerable research, development and standardisation of areal techniques. This book will present the areal framework that is being adopted by the international community. Whereas previous books have concentrated on the measurement aspects, this book concentrates on the characterisation techniques, i.e. how to interpret the measurement data to give the appropriate (functional) information for a given task. The first part of the book presents the characterisation methods and the second part case studies that highlight the use of areal methods in a broad range of subject areas - from automobile manufacture to archaeology.

Book Description
The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.

Book Description
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.

Book Description
X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.

Book Description
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.
