For more information, please see this article: Improving Time to Market. ECN (Engineering change notice) An official notice that a change has been approved. DHR (Device history record) A collection of records containg the production history of a medical device. See Computer-aided design and manufacturing, In parallel with the definition of process equipment, the manufacturing system designer must determine the most appropriate materials-handling techniques for the transfer of parts from machine to machine of each family of parts. PLM (Product lifecycle management) The management of the product record, including bills of materials, specifications, revisions and changes, from prototype through end-of-life. Engineering Forum Deviations may be planned or unplanned. NPD (New product development) The overall process of conceptualizing, designing, planning and commercializing a new product. See Materials-handling equipment, A quality assurance philosophy must be developed that emphasizes process control as the means to assure part conformance rather than emphasizing the detection of part nonconformance as a means of detecting an out-of-control process. ISO 14000 (International standards organization 14000) Standards and guidelines for environmental management systems. NPI (New product introduction) The market launch or commercialization of a new product. Manufacturing Systems Engineering synonyms, Manufacturing Systems Engineering pronunciation, Manufacturing Systems Engineering translation, English dictionary definition of Manufacturing Systems Engineering. Third Edition, AFS chapter sparks interest in metalcasting in local students, Taylor & Francis (Philadelphia, PA) will launch "Enterprise Information Systems," (EIS) a new quarterly journal, with an issue in early 2007, GEMA takes off: although some people think that the only place to build new manufacturing plants in the U.S. is in the southern states, a team of global companies has constructed one of the most flexible powertrain plants in the world in Michigan. Marcel Escudier is Emeritus Harrison Professor of Mechanical Engineering at the University of Liverpool. Topics covered include heat transfer, combustion, control, lubrication, robotics, instrumentation, and measurement. Prototype An engineering-quality sample build of a product, typically intended to test high-risk aspects of the design. The EBOM represents only the physical product being “engineered,” not the packaging or manufacturing consumables. Item Master List of all components that a manufacturer buys, builds or assembles into its products. MCAD Software (Mechanical computer aided design software) Software used by mechanical engineers to develop concepts and designs of mechanical systems. Fit is the ability of an item to physically interface with, interconnect with or become an integral part of another item. The design history file documents the design decisions made throughout the development of the device including sign-off events, change information, meeting notes, test data and reports and evidence that the device has been scrutinized carefully against design and performance specifications. See Simulation. Product Record A general term that describes all design, manufacturing, quality, sales and repair information about a product. Change Order See ECN (engineering change notice) and ECO (engineering change order). Revision A snapshot of a product, part, process, program, design or document at any moment in its development. This includes maintaining and properly distributing product files while following revision control procedures. document.write(''); This approach uses computer-integrated manufacturing technology to reduce the workers' influence on the manufacturing process.

Over 7,400 entriesThis new Dictionary provides definitions and explanations for mechanical engineering terms in the core areas of design, stress analysis, dynamics and vibrations, thermodynamics, and fluid mechanics, in over 7,400 clear and concise A to Z entries, many illustrated. Search engineering dictionary: Browse by letter: A; B; C; D; E; F; G; H; I; J; K; L; M; N; O; P; Q; R; S; T; U; V; W; X; Y; Z In our years of working with manufacturers — from high-tech electronic to automotive to medical device companies — we have learned the terms commonly used in their respective industries and compiled them into a list. See Computer-integrated manufacturing. ECR (Engineering change request) A change request listing proposed improvements or problems with components or assemblies. For more information see this article, Creating a Bill of Materials. In this example the “400000-00 Lawn Mower” shows the level 2 details of “100000-00 Assy Handle”: MWI (Manufacturing work instructions) Information and directions on how to perform a manufacturing task. Engineering Book Store During the manufacture of pieces, the parts are organized by the type of feature desired. For instance, a lawn mower may include the following elements: a handle assembly, a metal deck assembly, a control assembly, a motor and a blade assembly. The second approach uses computer-integrated manufacturing technology to help the workers make the best product possible. Compliance The practice of tracking whether or not a product complies with government-imposed regulations or a company’s self-imposed standards. Over 7,400 entriesThis new Dictionary provides definitions and explanations for mechanical engineering terms in the core areas of design, stress analysis, dynamics and vibrations, thermodynamics, and fluid mechanics, in over 7,400 clear and concise A to Z entries, many illustrated. UOM (Unit of measure) Describes how manufacturers use or buy a part. The DMR provides all information required to correctly build the current production revision of the device. Leverage this glossary to build your vocabulary of manufacturing acronyms and terms. NPD is also frequently referred to as “product development.”.
