The Boothroyd Dewhurst concept of DFMA allows a team to examine design alternatives and simplify the structure of the product before detail design has. Design for assembly (DFA) is a process by which products are designed with ease of assembly Starting in , Geoffrey Boothroyd and Peter Dewhurst developed a computerized version of the DFA method which allowed its. This chapter explains how the Boothroyd-Dewhurst (B&D) Design for Manufacture and Assembly (DFMA) works, discusses the experience and benefits of using.

Many of these rules and recommendations were presented together with practical examples showing how assembly difficulty could be improved.

We convene representatives from Fortune companies including corporate strategists, design engineers, manufacturing engineers, purchasing personnel and supply-chain managers. In addition, if the parts are provided with features which make it easier to grasp, move, orient and insert them, this will also reduce assembly time and assembly costs.

Teamwork, negotiation, adaptability, decision-making.

dewuurst Lots of great topics, great ideas, excellent examples of applications, strategies, processes. For example, inSidney Liebson, manager of manufacturing engineering for Xeroxestimated that his company would save hundreds of millions of dollars through the application of DFA.

The reduction of the number of parts in an assembly has the added benefit of generally reducing the total cost of parts in the assembly.

Design for assembly

Both were designed for fully automated assembly. For automatic assembly, tables of factors could be used to estimate the cost of automatic feeding and orienting and automatic insertion of the parts on an assembly machine.

All methods are now referred to as design for assembly methods. These criteria, together with tables relating assembly time to various design factors influencing part grasping, orientation and insertion, could be used to estimate total assembly time and to rate the quality of a product design from an assembly viewpoint.
