Product Design for Manufacture and Assembly

I use the book to complete projects information with more details about tooling costing, as the software does not provide this details.

It's really interesting the way in that this kind of books are written. I`ve admit that I bougth the book for some special chapters like the DFMA,Print Circuit Board design, Electrical conection and Wire harness design, Design for machining and Injection molding process. However all the information published into the charpers is really useful, and if you don't have any idea about other common process is a good way to introduce yourself in this, It's very useful to have an overview of all the main features to have present when you're involved in the product development o you are involve into a concurrent enginniering process. It`s a great job.

Overview Boothroyd and Dewhurst's Second Edition of Product Design for Manufacture and Assembly provides an accessible and reasonably thorough introductory treatment of some of the most common topics in the field of design for manufacture and assembly (DFMA). By introducing the theoretical underpinnings of DFMA in the opening chapter of the book, the authors provide context and support for the importance of the field in modern business, and draw attention to the many ancillary benefits of applying DFMA methodologies in a business environment. Subsequent chapters describe these methodologies, as well as major assembly and manufacturing processes in some detail. The authors also provide basic tools for cost analysis within the context of DFMA. On a whole, the book is a worthwhile read for novices or users of the authors' commercial software, but the content suffers at times in its dependence on that same software, and in its failure to explain or note omissions which were made in the favor of brevity. Materials and Process Selection The second chapter begins to elaborate in depth on some of the concepts developed in the first chapter by discussing the driving considerations in concurrent materials and fabrication process selection. While the chapter is useful in that it provides tabular references which document the compatibility of different engineering materials and processes, the chapter as a whole suffers from its methodological reliance upon the extensive databases included in commercial software which the authors market. Users of the software may find their exposition of its underlying algorithms useful, but those seeking an independent understanding of material and process selection may wish to consult other methodologies or references such as Ashby's Materials Selection in Mechanical Design, which are more user friendly, and are readily adaptable to manual application. Design for Assembly The third and fifth chapters of the book segue into the topic of assembly-both automatic and manual. Their treatment of assembly benefits from greater accessibility and independence from their software's methods, and the support of experimental results demonstrating the relationships which they discuss between part geometries and assembly. The general design guidelines are useful, and the empirically-derived equations are sufficient to allow the reader to perform basic analyses. Where the third and fifth chapters focus upon the assembly of mechanical components, fourth and sixth chapters of the book focus instead upon the challenges of designing and assembling electrical boards and wiring in a product. Though modest guidelines are suggested, the material in these chapters is primarily limited to the mechanical aspects of electrical component assembly, and focuses particularly on techniques for estimating the assembly time and cost of these components. The goal of their inclusion here seems to be not as an aid for the electrical engineer, but

As an academician this book is easy to read but practitioners will have no diffculty in understanding the content of this book. I rate this book as a great book because of its practicality and yet it is theoretically sound.

Boothroyd and Dewhurst are recognized as international experts on the re-engineering of electro-mechanical products. Their methodology and guidelines have been widely documented to make significant savings. I have used their techniques with dozens of products in many companies in North America with vast improvement. I have also taught these techniques to many, many engineers who have had the same success. The book is a good, comprehensive overview of designing products to ease thier assembly and manufacture. Other texts are available but most are not written as clearly.
