A Clear, Comprehensive Introduction to Standards in the Engineering Professions Standards supplement the design process by guiding the designer toward consistency, safety, and reliability. As daily life involves increasingly complex and sophisticated instruments, standards become indispensable engineering tools to ensure user safety and product quality. Primer on Engineering Standards: Expanded Textbook Edition delves into standards creation and compliance to provide students and engineers with a comprehensive reference. The different types of standards are dissected and discussed in terms of development, value, impact, interpretation, and compliance, and options are provided for situations where conformance is not possible. The process of standards creation is emphasized in terms of essential characteristics and common pitfalls to avoid, with detailed guidance on how, where, and with whom one may get involved in official development. Organized for both quick reference and textbook study, this new Expanded Textbook Edition provides a quick, clear understanding of critical concepts, ramifications, and implications as it: Introduces the concepts, history, and classification of standards, rules, and regulations Discusses the federal, state, and local government’s role in standards development and enforcement Distinguishes voluntary consensus standards, limited consensus standards, and jurisdictional versus non-jurisdictional government standards Covers the need for and process of exemptions to existing standards Examines the characteristics of a good standard, and discusses opportunities for involvement in development Includes case studies to demonstrate standards applications, and extensive appendices to direct further inquiry The successful design, fabrication, and operation of any product relies on foundational understanding of pertinent standards; indeed, standards and guidelines form a central pillar of the engineering profession. This helpful resource goes beyond a list of rules to help students and practitioners gain a better understanding of the creation, import, and use of standards.
This textbook covers in detail digitally-driven methods for adding materials together to form parts. A conceptual overview of additive manufacturing is given, beginning with the fundamentals so that readers can get up to speed quickly. Well-established and emerging applications such as rapid prototyping, micro-scale manufacturing, medical applications, aerospace manufacturing, rapid tooling and direct digital manufacturing are also discussed. This book provides a comprehensive overview of additive manufacturing technologies as well as relevant supporting technologies such as software systems, vacuum casting, investment casting, plating, infiltration and other systems. Reflects recent developments and trends and adheres to the ASTM, SI and other standards; Includes chapters on topics that span the entire AM value chain, including process selection, software, post-processing, industrial drivers for AM, and more; Provides a broad range of technical questions to ensure comprehensive understanding of the concepts covered.
This book assesses the state of the art of coatings materials and processes for gas-turbine blades and vanes, determines potential applications of coatings in high-temperature environments, identifies needs for improved coatings in terms of performance enhancements, design considerations, and fabrication processes, assesses durability of advanced coating systems in expected service environments, and discusses the required inspection, repair, and maintenance methods. The promising areas for research and development of materials and processes for improved coating systems and the approaches to increased coating standardization are identified, with an emphasis on materials and processes with the potential for improved performance, quality, reproducibility, or manufacturing cost reduction.
The selection of the proper materials for a structural component is a critical activity that is governed by many, often conflicting factors. Incorporating materials expert systems into CAD/CAM operations could assist designers by suggesting potential manufacturing processes for particular products to facilitate concurrent engineering, recommending various materials for a specific part based on a given set of characteristics, or proposing possible modifications of a design if suitable materials for a particular part do not exist. This book reviews the structural design process, determines the elements, and capabilities required for a materials selection expert system to assist design engineers, and recommends the areas of expert system and materials modeling research and development required to devise a materials-specific design system.
