Download or read book Characterisation of Areal Surface Texture written by Richard Leach and published by Springer Science & Business Media. This book was released on 2013-04-03 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Optical Measurements written by Franz Mayinger and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing possibilities of computer-aided data processing have caused a new revival of optical techniques in many areas of mechanical and chemical en gineering. Optical methods have a long tradition in heat and mass transfer and in fluid dynamics. Global experimental information is not sufficient for developing constitution equations to describe complicated phenomena in fluid dynamics or in transfer processes by a computer program . Furthermore, a detailed insight with high local and temporal resolution into the thermo-and fluiddynamic situations is necessary. Sets of equations for computer program in thermo dynamics and fluid dynamics usually consist of two types of formulations: a first one derived from the conservation laws for mass, energy and momentum, and a second one mathematically modelling transport processes like laminar or turbulent diffusion. For reliably predicting the heat transfer, for example, the velocity and temperature field in the boundary layer must be known, or a physically realistic and widely valid correlation describing the turbulence must be avail able. For a better understanding of combustion processes it is necessary to know the local concentration and temperature just ahead of the flame and in the ignition zone.

Download or read book Digital Optical Measurement Techniques written by and published by . This book was released on 2018-05 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its ruggedness and often contactless characteristics, optical systems are one of the most adopted, particularly when fast changes in displacement need to be measured. Moreover, due to the physical principles that support the operation of some of those systems (e.g., optical interferometry), they allow the measurement of linear displacements with resolutions and accuracies below the nanometer. Miniaturization and mass replications have begun to lead the optical industry in the transition from traditional analog to novel digital optics. Digital optics is information optics in its maturity. It assumes using digital processing units as an integral part of optical imaging and measurement systems. Digital processors are used both for control of optical systems and for processing optical signals. One of the main use of digital signal processing in optical imaging and measuring devices is data calibration, and, in particular, data denoising.Digital Optical Measurement Techniques presents cutting-edge information on the development and application of optical techniques and laser technology in engineering.

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 404 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.
