Design For Manufacturing & Assembly

Course Objectives:

- To developing students be able to design products that are simple in structure, easier to manufacture, assemble and service

- To train students to integrate product and process design to ensure an optimum combination of function and manufacturability

Expected Course Outcome:

- Upon completion of this course, the student shall be able to:

- Design engineering products by structured design methodologies aiming at ease of manufacture and assembly.

- Adopt methods and approaches for developing, implementing, and nurturing an effective DFMA process within the firm.
