ENGINEERING TOOLS AND METHODS
Topical Outline DAY ONE • What is DFM+A
Design for Manufacturing & Assembly (DFM/DFA) 2 Days | Classroom Seminar I.D.# 92047 Design for Manufacturing and Assembly (DFM+A), pioneered by Boothroyd and Dewhurst, has been used by many companies around the world to develop creative product designs that use optimal manufacturing and assembly processes. Correctly applied, DFM+A analysis leads to significant reductions in production cost, without compromising product time-to-market goals, function- ality, quality, serviceability, or other attributes. In this two-day seminar, you will not only learn the Boothroyd Dewhurst Method, you will actually apply it to your own product design! This seminar will include information on how DFM+A fits in with QFD, concurrent engineering, robust engineering, and other disciplines. In addition, there will be a brief demonstration of computer software tools, which simplify the DFM+A analysis. Each participant will receive and use the hard-bound authoritative reference textbook, “Product Design for Manufacture and Assembly,” written by Geoffrey Boothroyd, Peter Dewhurst and Winston Knight. Learning Objectives By attending this seminar, you will be able to: • Perform Design for Assembly (DFA) Analysis using the BDI Manual (Worksheet) Method • Perform DFM Analysis (manufacturing cost estimation) • Apply Design for Service (DFS) Principles • Reduce your company’s production costs by analyzing and eliminating the factors that greatly affect the time, cost, and quality of manufacturing, assembly and service processes • Utilize effective analysis, brainstorming, and trade-off techniques for redesigning assemblies and subassemblies Who Should Attend Product designers, product engineers, or manufacturing engineers will benefit by attending this seminar. Individuals involved in a new or ongoing product development process will also benefit by learning how to help synchronize and optimize fabrication and assembly activities. This course is most effective when attended by product development team members; however, this is not a requirement for attendance. NOTE: You are strongly encouraged to bring a sample or drawing of one of your own designs to analyze during the workshop on Day Two. You are also asked to bring a calculator capable of making simple calculations. Prerequisites An engineering undergraduate degree in any discipline would be beneficial.
