This FMEA Standard describes Potential Failure Mode and Effects Analysis in Design (DFMEA) and Potential Failure Mode and Effects Analysis in Manufacturing and Assembly Processes (PFMEA). It assists users in the identification and mitigation of risk by providing appropriate terms, requirements, ranking charts, and worksheets. As a Standard, this document contains requirements "must" and recommendations "should" to guide the user through the FMEA process. The FMEA process and documentation must comply with this Standard as well as any corporate policy concerning this Standard. Documented rationale and agreement with the customer is necessary for deviations in order to justify new work or changed methods during customer or third-party audit reviews. Widespread use of design and process FMEA is a benefit to consumers and manufacturers. The application of FMEA has been in place in the automotive industry since the late 1960's with emphasis on standard ranking criteria and forms since the early 1990's. The FMEA methodology has proven itself useful in the prevention and mitigation of potential failure modes. However, a growing need developed for improved failure mode ranking criteria and a change in thinking about the use of the Risk Priority Number (RPN). This standard includes updated ranking charts and de-emphasizes the use of an RPN threshold as the primary factor in determining preventive or corrective action efforts. It also includes a Boundary Diagram and Process Flow Diagram example as use of these tools has increased. The section for Potential Failure Mode and Effects Analysis for Machinery (Machinery FMEA) is a form of Design FMEA and has been removed. Machinery FMEA is a type of Design FMEA for equipment. There are numerous books, reference manuals and training references on the subject of FMEA. This standard serves as a common starting point for the development of an effective DFMEA and PFMEA.
Outlines the correct procedures for doing FMEAs and how to successfully apply them in design, development, manufacturing, and service applications There are a myriad of quality and reliability tools available to corporations worldwide, but the one that shows up consistently in company after company is Failure Mode and Effects Analysis (FMEA). Effective FMEAs takes the best practices from hundreds of companies and thousands of FMEA applications and presents streamlined procedures for veteran FMEA practitioners, novices, and everyone in between. Written from an applications viewpoint—with many examples, detailed case studies, study problems, and tips included—the book covers the most common types of FMEAs, including System FMEAs, Design FMEAs, Process FMEAs, Maintenance FMEAs, Software FMEAs, and others. It also presents chapters on Fault Tree Analysis, Design Review Based on Failure Mode (DRBFM), Reliability-Centered Maintenance (RCM), Hazard Analysis, and FMECA (which adds criticality analysis to FMEA). With extensive study problems and a companion Solutions Manual, this book is an ideal resource for academic curricula, as well as for applications in industry. In addition, Effective FMEAs covers: The basics of FMEAs and risk assessment How to apply key factors for effective FMEAs and prevent the most common errors What is needed to provide excellent FMEA facilitation Implementing a "best practice" FMEA process Everyone wants to support the accomplishment of safe and trouble-free products and processes while generating happy and loyal customers. This book will show readers how to use FMEA to anticipate and prevent problems, reduce costs, shorten product development times, and achieve safe and highly reliable products and processes.
Author D. H. Stamatis has updated his comprehensive reference book on failure mode and effect analysis (FMEA). This is one of the most comprehensive guides to FMEA and is excellent for professionals with any level of understanding. This book explains the process of conducting system, design, process, service, and machine FMEAs, and provides the rationale for doing so. Readers will understand what FMEA is, the different types of FMEA, how to construct an FMEA, and the linkages between FMEA and other tools. Stamatis offer a summary of tools/methodologies used in FMEA along with a glossary to explain key terms and principles. the updated edition includes information about the new ISO 9000:2000 standard, the Six Sigma approach to FMEA, a special section on automotive requirements related to ISO/TS 16949, the orobustnesso concept, and TE 9000 and the requirements for reliability and maintainability. the accompanying CD-ROM offers FMEA forms and samples, design review checklist, criteria for evaluation, basic reliability formulae and conversion failure factors, guidelines for RPN calculations and designing a reasonable safe product, and diagrams, and examples of FMEAs with linkages to robustness.
Risk is everywhere. It does not matter where we are or what we do. It affects us on a personal level, but it also affects us in our world of commerce and our business. This indispensable summary guide is for everyone who wants some fast information regarding failures and how to deal with them. It explores the evaluation process of risk by utilizing one of the core methodologies available: failure modes and effects analysis (FMEA). The intent is to make the concepts easy to understand and explain why FMEA is used in many industries with positive results to either eliminate or mitigate risk.
This SAE Recommended Practice was jointly developed by Chrysler, Ford and General Motors under the sponsorship of the United States Council for Automotive Research (USCAR). This document introduces the topic of potential Failure Mode and Effects Analysis (FMEA) and gives general guidance in the application of the technique. An FMEA can be described as a systemized group of activities intended to: (a) recognize and evaluate the potential failure of a product/process and its effects, (b) identify actions which could eliminate or reduce the chance of the potential failure occurring, and (c) document the process. It is complementary to the design process of defining positively what a design must do to satisfy the customer.
Demonstrates How To Perform FMEAs Step-by-StepOriginally designed to address safety concerns, Failure Mode and Effect Analysis (FMEA) is now used throughout the industry to prevent a wide range of process and product problems. Useful in both product design and manufacturing, FMEA can identify improvements early when product and process changes are
A unique, design-based approach to reliability engineering Design for Reliability provides engineers and managers with a range of tools and techniques for incorporating reliability into the design process for complex systems. It clearly explains how to design for zero failure of critical system functions, leading to enormous savings in product life-cycle costs and a dramatic improvement in the ability to compete in global markets. Readers will find a wealth of design practices not covered in typical engineering books, allowing them to think outside the box when developing reliability requirements. They will learn to address high failure rates associated with systems that are not properly designed for reliability, avoiding expensive and time-consuming engineering changes, such as excessive testing, repairs, maintenance, inspection, and logistics. Special features of this book include: A unified approach that integrates ideas from computer science and reliability engineering Techniques applicable to reliability as well as safety, maintainability, system integration, and logistic engineering Chapters on design for extreme environments, developing reliable software, design for trustworthiness, and HALT influence on design Design for Reliability is a must-have guide for engineers and managers in R&D, product development, reliability engineering, product safety, and quality assurance, as well as anyone who needs to deliver high product performance at a lower cost while minimizing system failure.
The recognition that all well-managed companies are interested in preventing or at least minimizing risk in their operations is the concept of risk management analysis. This pocket guide explores the process of evaluation of risk by utilizing one of the core methodologies available: the failure mode and effect analysis (FMEA). The intent in this “Pocket FMEA” is to provide the reader with a booklet that makes the FMEA concept easy to understand and provide some guidelines as to why FMEA is used in so many industries with positive results. The booklet is not a complete reference on FMEA, but rather a summary guide for anyone who wants some fast information regarding failures and how to deal with them. It covers risk, reliability and FMEA, prerequisites of FMEA, what an FMEA is, robustness, the FMEA form and rankings, types of FMEA, and much more.
