Design for Manufacture and Assembly (DFMA)A One-Day Short CourseTwo popular best practices for achieving product quality are Design for Manufacturing (DFM) and Design for Assembly (DFA). Together they are referred to as DFMA. These best practices give product designers a structure for considering the downstream costs and quality of the parts and assemblies they design.This course begins with a discussion of the sources of quality in a product. It emphasizes design best practices that can lead to quality products while minimizing the cost and time to market. This discussion serves to show how DFMA methods are one part of an overall quality product design program. DFM methods are unique for each manufacturing method. In this course the DFM material focuses on machining, injection molding and sheet metal practices. Sufficient basics of important features of each of these processes will be discussed so that the participants can review their own company design standards with an increased awareness of the effects of design features on cost and quality. DFA studies center on a thirteen measures that were originally developed for the book The Mechanical Design Process. The measures are the basis of a DFA worksheet for the evaluation and comparison of assemblies. Studying these thirteen gives the participants a strong background in how the design of parts affects their assemblability, cost and quality. Methods covered include: assessment of the theoretical minimum number of parts in an assembly, the effect of fasteners on the assembly, the effect of assembly sequence, concerns for part interfaces and nine other issues. The course concludes with planning for how to integrate DFMA into the organization. Who should attend
