  1. Design for Manufacturability

  2. Design for Manufacturability • Read about “Design for Manufacturability”. The following are good referenced but not the only ones: • http://www.npd-solutions.com/dfmguidelines.html • In particular points 1, 2, 3, 5, 7, 9, 10, 12 • http://www.design4manufacturability.com/DFM_article.htm • In particular The Importance of Early Concept & Product Architecture Decisions

  3. The Old Days • Before DFM, the motto was "I designed it; you build it!“ • Designs were then thrown over the wall leaving manufacturing people with the dilemma of either objecting (but its to late to change the design!) or struggling to launch a product that was not designed for manufacturability.

  4. Design for Manufacturability • Design for manufacturability is the process of proactively designing products to optimize all the manufacturing functions: • fabrication, • assembly, • test, • procurement, • shipping, • delivery, • service, • and repair, and

  5. Design for Manufacturability • Assures: • the best cost, • quality, • reliability, • regulatory compliance, • safety, • time-to-market, • and customer satisfaction.

  6. Design for Manufacturability • Companies that have applied DFM have realized substantial benefits. • Costs and time-to-market are often cut in half with significant improvements in • product line breadth, • delivery, • customer acceptance, • in general, competitive posture, • quality, • Reliability and, • serviceability.

  7. You should Consider • Simplify the design and reduce the number of parts • Standardize and use common parts and materials • Design for ease of fabrication (Mechanical Parts) • Design for ease of assembly (Mechanical and Electronics) • Avoid unnecessarily tight tolerances that are beyond the natural capability of the manufacturing processes • Mistake-proof product design and assembly (poka-yoke) so that the assembly process is unambiguous • Minimize flexible parts and interconnections

  8. You should Consider • Design for efficient joining and fastening (Easy assembly and disassembly) • Design modular products • Design for automated production • Design printed circuit boards for assembly • Design for testability

  9. Design for Manufacturability • Demonstrate your awareness on the importance of making the right choices in the early stages in the project

  10. Design for Manufacturability • Develop a one to two page, section for manufacturability and indicate in particular the principles you will emphasize in your project
