Laser Fabrication And Machining Of Materials

This book covers the fundamental principles and physical phenomena behind laser-based fabrication and machining processes. It also gives an overview of their existing and potential applications. With laser machining an emerging area in various applications ranging from bulk machining in metal forming to micromachining and microstructuring, this book provides a link between advanced materials and advanced manufacturing techniques. The interdisciplinary approach of this text will help prepare students and researchers for the next generation of manufacturing.

Advanced materials are becoming increasingly important as substitutes for traditional materials and as facilitators for new and unique products. They have had a considerable impact on the development of a wide range of strategic technologies. Structural ceramics, biomaterials, composites and intermetallics fall under this category of advanced mater

LASER-ASSISTED MACHINING This unique book develops exhaustive engineering perceptions of different laser-assisted techniques, reviews the engineering context of different laser fabrication techniques, and describes the application of laser-assisted fabrication techniques. Lasers are essential in the area of material processing because they can produce coherent beams with little divergence. The fabrication process known as surface cladding includes joining (soldering, welding), material removal (laser-aided drilling, cutting, etc.), deformation (extrusion, bending), and material addition. Some remarkable advantages of laser-assisted material development include faster processing rates and preservation of essential alloying components. However, the lack of widespread understanding of various material phenomena and how laser parameters affect them prevents the technology from being widely accepted on an industrial scale. Among the subjects Laser-Assisted Machining covers include high-powered lasers in material processing applications, laser-based joining of metallic and non-metallic materials, direct laser cladding, laser surface processing, laser micro and nano processing, emerging laser materials processing techniques, solid-state lasers, laser cutting, drilling and piercing, laser welding, laser bending or forming, laser cleaning, laser automation and in-process sensing, femtosecond laser micromachining, laser-assisted micro-milling/grinding, laser-assisted jet electrochemical micro-machining, laser-assisted water jet micro-machining, hybrid laser-electrochemical micromachining process, quill and nonreciprocal ultrafast laser writing, laser surface engineering, ultrashort pulsed laser surface texturing, laser interference patterning systems, laser interference lithography, laser-guided discharge texturing. Audience The book will be used by researchers in the fields of manufacturing technology and materials science as well as engineers and high-level technicians for a better understanding of various innovative and novel techniques to cope with the need of micromachining, as well as microfabrication industries for successful implementation of microproduct manufacturing.

Laser Machining: Theory and Practice addresses state-of-the-art laser machining in a way useful for research- ers, academicians and practitioners, particularly manufacturing engineers, who are considering lasers as a solution to the machining requirements of their factories and plants. This book provides detailed information on the theory behind laser machining, as well as its requirements, uses and applications. In order to place laser machining in its correct context, the author begins with an overview of conventional material removal processes and go on to describe in detail the physical mechanisms involved in lasers, the different types of lasers involved in laser machining, and laser machining systems, which include optics, positioning systems, manipulators, etc. The theoretical treatment of the laser includes a section on the basics of heat transfer and fluid mechanics, and analyses of one, two and three-dimensional laser machining processes. The book closes with a description of state-of-the-art laser machining applications in research and industrial practice.

Provides an in-depth understanding of the fundamentals of a wide range of state-of-the-art materials manufacturing processes Modern manufacturing is at the core of industrial production from base materials to semi-finished goods and final products. Over the last decade, a variety of innovative methods have been developed that allow for manufacturing processes that are more versatile, less energy-consuming, and more environmentally friendly. This book provides readers with everything they need to know about the many manufacturing processes of today. Presented in three parts, Modern Manufacturing Processes starts by covering advanced manufacturing forming processes such as sheet forming, powder forming, and injection molding. The second part deals with thermal and energy-assisted manufacturing processes, including warm and hot hydrostamping. It also covers high speed forming (electromagnetic, electrohydraulic, and explosive forming). The third part reviews advanced material removal process like advanced grinding, electro-discharge machining, micro milling, and laser machining. It also looks at high speed and hard machining and examines advances in material modeling for manufacturing analysis and simulation. Offers a comprehensive overview of advanced materials manufacturing processes Provides practice-oriented information to help readers find the right manufacturing methods for the intended applications Highly relevant for material scientists and engineers in industry Modern Manufacturing Processes is an ideal book for practitioners and researchers in materials and mechanical engineering.

Laser assisted fabrication involves shaping of materials using laser as a source of heat. It can be achieved by removal of materials (laser assisted cutting, drilling, etc.), deformation (bending, extrusion), joining (welding, soldering) and addition of materials (surface cladding or direct laser cladding). This book on ́Laser assisted Fabrication’ is aimed at developing in-depth engineering concepts on various laser assisted macro and micro-fabrication techniques with the focus on application and a review of the engineering background of different micro/macro-fabrication techniques, thermal history of the treated zone and microstructural development and evolution of properties of the treated zone.

Advances in Laser Materials Processing: Technology, Research and Application, Second Edition, provides a revised, updated and expanded overview of the area, covering fundamental theory, technology and methods, traditional and emerging applications and potential future directions. The book begins with an overview of the technology and challenges to applying the technology in manufacturing. Parts Two thru Seven focus on essential techniques and process, including cutting, welding, annealing, hardening and peening, surface treatments, coating and materials deposition. The final part of the book considers the mathematical modeling and control of laser processes. Throughout, chapters review the scientific theory underpinning applications, offer full appraisals of the processes described and review potential future trends. A comprehensive practitioner guide and reference work explaining state-of-the-art laser processing technologies in manufacturing and other disciplines Explores challenges, potential, and future directions through the continuous development of new, application-specific lasers in materials processing Provides revised, expanded and updated coverage

New chapters on bending and cleaning reflect the changes in the field since the last edition, completing the range of practical knowledge about the processes possible with lasers already familiar to users of this well-known text. Professor Steen's lively presentation is supported by a number of original cartoons by Patrick Wright and Noel Ford, which will bring a smile to your face and ease the learning process. From the reviews: "...well organized, and the text is very practical...The engineering community will find this book informative and useful." (OPTICS AND PHOTONICS NEWS, July/August 2005)
