Applied Manufacturing Process Planning: With Emphasis on
Metal Forming and Machining
An application-oriented text that closely follows actual manufacturing plan development. Textual features include numerous illustrations and photos, chapters on metal removal and machining to support the chapters on the manufacturing plan, and review questions at the end of each chapter. DLC: Manufacturing process--Planning.
From the Inside Flap
Applied Manufacturing Process Planning is unique in that it is application-oriented and follows actual manufacturing plan development closely. Some differences do exist between manufacturers, such as reporting relationships and product design, but basic plan development is common.
Chapters are organized in the sequence used to develop manufacturing plans in actual practice. Each chapter is illustrated to clarify the discussion of the subject involved, and examples are provided. Also, chapters are provided that serve as support and refresher updates to chapters that detail elements of a manufacturing plan. These pages are identified with shaded edges.
Machined parts, upset parts, and sheet metal parts have been selected as a representative cross section of manufactured parts for detailed discussion and illustration of manufacturing plan development. The planning functions discussed and illustrated in this book can be employed to develop manufacturing plans for most other manufactured products. Key parts of a manufacturing plan for machined parts are:
Processing: Processing is determining the operations and sequence of operations required to manufacture a part. Machining dimensions, manufacturing tolerances, and locating surfaces are also determined. Tolerance Charting: Tolerance charting is mathematically checking, verifying, and graphically displaying (charting) the machining dimensions, manufacturing tolerances, and stock removal of each operation planned in processing—all from the specified locating points. Workpiece Holding: Workpieces must rest, during machining, on the identical locating surfaces specified in processing and confirmed with tolerance charting. Clamping must keep the workpiece in contact with the locating surfaces; supports are sometimes required to prevent distortion caused by clamping and/or tool pressures.
Processing, tolerance charting, and workpiece holding of a part must be developed to be in complete agreement; afterwards, ancillary, auxiliary, and support services, and costs are added to complete a manufacturing plan.
Chapters on manufacturing plan elements of special machines, machine selection, and group technology are provided. Developing a manufacturing plan for metal-worked parts follows the same general course as for machined parts; however, actual processes, tooling, and production materials are unique to that type of manufacture. Chapters in this area describe and illustrate processes and tooling used, as well as similarities and differences from machining processes.
The book is designed for use in manufacturing, mechanical, and industrial engineering courses in two- and four-year schools of engineering, technology, and skilled trades.
Flexibility in the use of the book exists in that individual chapters may be used to teach specific subjects—that is, tolerance charting, work holding, machining processes, or others may be studied in any sequence and in conjunction with other source material. However, where a complete manufacturing plan is to be studied and developed, part design analysis, manufacturing processing, and tolerance charting should be studied in that order.
The book will prove helpful to individuals involved in both mechanical and manufacturing engineering as well as individuals transiting from skilled trades to manufacturing engineering. Newly graduated manufacturing engineers will find the text a valuable guide and reference in the application of theory to practice.
One proviso—the book user should have a working knowledge of basic machining processes, math, and materials to use it effectively.
The authors' careers in industry, including years of hands-on experience at levels from Process Engineer to Manager of Manufacturing Engineering at General Motors, Wright Aeronautical, Chrysler, General Dynamics, EX-CELL-0, Modco-Valenite, and Carmet companies, provide the first-hand knowledge required for a book of this kind.
Both authors have taught Manufacturing Engineering courses at Lawrence Institute of Technology (now Lawrence Technological University), and both are active as consultants.
