Design for Manufacture and Assembly (DFM/DFA)

This seminar provides a functional understanding of the principles involved in conducting a Design for Manufacture/Design for Assembly study. DFM/DFA can support both manual and automated processes resulting in significant cost savings through simpler designs with fewer components. Related topics include workstation layouts, ergonomic considerations and errorproofing. Actual examples from the automotive industry are used to support the lecture and participants complete actual design efficiency using the DFM/DFA worksheet.

What Will You Learn

By attending this seminar, you will be able to:
  • Recognize and list the benefits of the DFM/DFA method in creating product designs which support manufacturing processes leading to short and long term product cost savings
  • Outline a Robust Manufacturing Plan that optimizes and simplifies product design without sacrificing quality
  • Objectively determine which designs would be suitable as DFM/DFA candidates
  • Perform the essential stages of a Design for Manufacture process including the analysis required to overcome typical manufacturing difficulties encountered in product design
  • Construct an actual DFM/DFA worksheet and calculate design efficiency using an instructor provided project

Is This Course For You

Product Engineers, Designers and Managers, Manufacturing and Tooling Engineers, and Project Managers who desire to understand DFM/DFA as a product design tool to increase manufacturability of product assemblies. The course is best suited for individuals in the manufacturing industry and is beneficial to OEMs and Tier suppliers.
