Design for manufacturing or DFM is a very important practical activity in Mechanical design engineering.

Converting concept  into designs which can be manufactured and ready for implementation is a key skill in product development.

This course attempts to cover the basics of designing for manufacturing including selecting a suitable process based on various criteria and designing for the process to reduce cost and improve ease of manufacturing .

Topics covered are


  1. Importance of Process selection

  2. Parameters and Criteria for selection

  3. Comparison of processes

  4. Process- Shape matrix

  5. Section wall thickness and Tolerance ranges

  6. Cost associated

  7. Part complexity and part cost

  8. Prototyping vs production

  9. Case studies in process selection

  10. Designing for Forging - principles and guidelines

  11. Designing for Casting - principles and guidelines

  12. Design for Injection Molding  - Principles and guidelines.

  13. Exercises to practice


The learning outcome of this course is to develop a strong basic comparative understanding of various processes and get started with designing as per certain processes to build DFM skills for mechanical design & product development.

Course will be best suitable for  Mechanical design engineers who want to level up their DFM knowledge and skills .
