Lesson 246 of IEKC Industrial Engineering ONLINE Course Notes.
My advocacy now is IEs must first concentrate on improving engineering elements and then move into productivity managerial elements and non-engineering areas. Machine work study or machine effort improvement, value engineering and design for manufacturing and assembly are major engineering based IE methods. All are available as existing methods.

Design for Manufacturing: A Structured Approach

Design for Manufacturing assists anyone not familiar with various manufacturing processes in better visualizing and understanding the relationship between part design and the ease or difficulty of producing the part.
Decisions made during the early conceptual stages of design have a great effect on subsequent stages. In fact, quite often more than 70% of the manufacturing cost of a product is determined at this conceptual stage, yet manufacturing is not involved. Through this book, designers will gain insight that will allow them to assess the impact of their proposed design on manufacturing difficulty.
The vast majority of components found in commercial batch-manufactured products, such as appliances, computers and office automation equipment are either injection molded, stamped, die cast, or (occasionally) forged. This book emphasizes these particular, most commonly implemented processes.
In addition to chapters on these processes, the book touches upon material process selection, general guidelines for determining whether several components should be combined into a single component or not, communications, the physical and mechanical properties of materials, tolerances, and inspection and quality control.
In developing the DFM methods presented in this book, he has worked with over 30 firms specializing in injection molding, die-casting, forging and stamping.
Implements a philosophy which allows for easier and more economic production of designs
Educates designers about manufacturing
Emphasizes the four major manufacturing processes
WHAT IS DESIGN FOR MANUFACTURE AND ASSEMBLY?
"To manufacture" refers to the manufacturing of the individual component parts of a product or assembly
"To assemble" refers to the addition or joining of parts to form the completed product.
The term "design for manufacture" (or DFM) means the design for ease of manufacture of the collection of parts that will form the product after assembly.
"Design for assembly" (or DFA) means the design of the product for ease of assembly.
Thus, "design for manufacture and assembly" (DFMA) is a combination of DFA and DFM.
DFMA process is used for three main activities:
1. As the basis for providing guidance to the design team in simplifying the product structure, to reduce manufacturing and assembly costs.
2. As a tool to study competitors' products and quantify manufacturing and assembly difficulties.
3. To support should-cost models.
Once methods for analyzing assembly difficulties were developed in the 1970s, it was found that the simplification of products by reducing the number of separate parts through DFA—on the order of 50% on average—could easily achieve substantial reductions in assembly costs. Much more important, however, was the fact that even greater savings could be achieved in the cost of the parts. The ability to estimate both assembly and part manufacturing costs at the earliest stages of product design is the essence of DFMA.
Much of the DFMA methodology involves analytical tools that allow designers and manufacturing engineers to estimate the manufacturing and assembly costs of a proposed product before detailed design has taken place. The text book by Boothroyd et al. provides the basic equations and data that allow manufacturing and assembly cost estimates to be made. Thus, for a limited range of materials and processes the engineer or student (reader) can make cost estimates for real parts and assemblies and, therefore, become familiar with the details of the methods employed and the assumptions made.
The ability to estimate both assembly and part manufacturing costs at the earliest stages of product design is the essence of DFMA. A primary objective of DFMA development has been to develop economic models of manufacturing processes, based on product design information, and which require a minimum of manufacturing knowledge.
Reported Benefits of DFMA
In 1988 Ford Motor Company reported that Boothroyd DFA software had helped them save billions of
dollars on their Taurus line of automobiles. Later, General Motors (GM) made comparisons between its assembly plant at Fairfax, Kansas, which made the Pontiac Grand Prix, and Ford's Atlanta assembly plant for its Taurus and Mercury Sable models. GM found a large productivity gap and concluded that 41% of the gap could be traced to the manufacturability of the two designs. For example, the Ford car had fewer parts—10 in its front bumper compared with 100 in the GM Pontiac—and the Ford parts fit together more easily.
Subsequently , GM has become one of the leading users of DFMA. It became a driver of quality and cost improvement through technical improvements to both product and process. It was made an integral part of engineering and manufacturing employee training.
Ingersoll-Rand Company reported that the use of DFMA software from Boothroyd Dewhurst, Inc., slashed product development time from two years to one. Examples of benefits: The number of parts in a portable compressor radiator and oil-cooler assembly from 80 to 29, decreased the number of fasteners from 38 to 20, trimmed the number of assembly operations from 159 to 40 and reduced assembly time from 18.5 to 6.5min. The new design went into full production in February, 1990.
DFMA efforts at Hewlett Packard Loveland started in the mid-1980s with redesign of existing products and continued with application to new product design. During these studies, one to three manufacturing engineers interacted frequently with the R&D team members and gave their suggestions and opinion. The studies proved the benefits of DFMA and eventually, by 1992, HP Loveland had incorporated DFMA into a formal concurrent engineering approach. There was significant improvement in their product manufacturing and assembly costs.
DFMA and Value Analysis
DFMA can be compared with Value Analysis. The objectives of DFMA and value analysis are the same. If some think that value analysis is more comprehensive, they have to realize that 13 value analysis techniques of L.D. Miles does not include the steps advocated in DFMA. DFMA is a more technically intensive method. DFMA is meant to be applied early in the design cycle and value analysis does not have any techniques or tools to give proper attention to the structure of the product and its possible simplification. Hence value engineering has to include DFMA in its techniques appropriately. DFMA is a systematic step-by-step procedure that can be applied at all stages of design and that challenges the designer or design team to justify the existence of all the parts and to consider alternative designs. Experience has shown that DFMA still makes significant improvements of existing products even after value analysis has been carried out.
*Design for Manufacture and Rapid Prototyping Both Seek the Same Size Prize: A Better Product Made Faster.
Mechanical Engineering. Sep 1999, 121(09): 72-74 (3 pages)
DFMA One Among Many Techniques
Since the introduction of DFMA, many more design based techniques have been proposed, for example, design for quality (DFQ), design for competitiveness (DFC), design for reliability, and many more. Design for performance is also specially advocated now whereas Miles argued that in his time design for performance is getting all the attention and design for value is not getting attention. Boothroyd remarks that DFMA is the subject that has been neglected over the years, while adequate consideration has always been given to the design of products for performance, appearance, etc. DFMA tools also encourage dialogue between designers and the manufacturing engineers and any other individuals who play a part in determining final product costs during the early stages of design. This means that teamwork is encouraged and the benefits of simultaneous or concurrent engineering can be achieved.
DFMA is an important technique to be used in product industrial engineering.

In order to compete in the current commercial environment companies must produce greater product variety, at lower cost, all within a reduced product life cycle. To achieve this, a concurrent engineering philosophy is often adopted. In many cases the main realization of this is Design for Manufacture and Assembly (DFM/A). There is a need for in-depth study of the architectures for DFM/A systems in order that the latest software and knowledge-based techniques may be used to deliver the DFM/A systems of tomorrow. This architecture must be based upon complete understanding of the issues involved in integrating the design and manufacturing domains. This book provides a comprehensive view of the capabilities of advanced DFM/A systems based on a common architecture.

Integrated Design of a Product Family and Its Assembly System
Pierre De Lit, Alain Delchambre
Springer Science & Business Media, 28-Jun-2011 - Science - 281 pages
The last two decades have witnessed important shifts in customers' behaviour. Companies now need to integrate customers in their strategies and manufacturers have to propose a large variety of products to meet the market's demand. Increasing the range of PVs attracts and retains customers, yet it dramatically augments the cost and complexity of the manufacturing systems. As many decisions taken at the design stage of the product are decisive for its entire life, it is crucial to integrate the process and the assembly system when designing the product.
Integrated Design of a Product Family and Its Assembly System presents an integrated approach for the design of a product family and its assembly system, whose main principles consider the product family as a fictitious unique product for which the assembly system is to be devised. It imposes assembly and operation constraints as late as possible in the design process to get liberties in the system design, and adapts the product family at each design stage to integrate the new constraints related to the successive design choices.
Integrated Design of a Product Family and Its Assembly System is an important, must-have book for researchers and Ph.D. students in Computer-Integrated Manufacturing, Mechanical Engineering, and Manufacturing, as well as practitioners in the Design, Planning and Production departments in the manufacturing industry. Integrated Design of a Product Family and Its Assembly System is also suitable for use as a textbook in courses such as Computer-Aided Design, Concurrent Engineering, Design for Assembly, Process Planning, and Integrated Design.
