In Mechanical Assemblies: Their Design, Manufacture, and Role in Product Development , author Daniel E. Whitney draws on more than thirty years of academic and industry experience to fill this significant gap in the mechanical engineering curriculum.
Assembly is the process by which parts become products that do useful things. It is therefore fundamental to the work of every mechanical engineer. Yet the design of assemblies and the process of assembling them are rarely taught in universities.
The first book to develop a systematic approach to the modeling and design of assemblies, this text addresses the subject on two levels. Assembly in the Small develops a systematic theory for the design of assemblies with their functions in mind, starting from the basic principles of mechanical constraint and including methods for representing assemblies mathematically. In addition, important assembly analysis techniques such as predicting variation and generating assembly sequences are covered using a consistent mathematical formulation. Assembly in the Large deals with the role of assemblies in product development, including product architecture, design for assembly, and manufacturing strategy, as well as design and evaluation of assembly processes and systems.
Places the design of assemblies in the context of product architecture and industry demand for numerous product models and versions with short delivery times.
Describes methods of designing assembly workstations and systems.
Includes numerous examples from the automobile, aircraft, and consumer product industries.
Provides several computer programs that illustrate principles in the book
Utilizes MATLAB for calculations related to assembly systems
A CD packaged with the book contains appendixes to the book and software that accompanies the exercises and examples in the text.
