Manufacturing Process selection and Design for Manufacturing

Course Summary

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 :
- Importance of Process selection
- Parameters and Criteria for selection
- Comparison of processes
- Process- Shape matrix
- Section wall thickness and Tolerance ranges
- Cost associated
- Part complexity and part cost
- Prototyping vs production
- Case studies in process selection
- Designing for Forging - principles and guidelines
- Designing for Casting - principles and guidelines
- Design for Injection Molding - Principles and guidelines.
- 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 .
