Design for Manufacturing (DFM)

Course Overview

This course explores the principles of Design for Manufacturing, emphasizing the relationship between product design and manufacturing processes. Students will learn how to design products with manufacturability in mind, considering factors such as materials, processes, and assembly.

Course Objectives

  • Understand the principles of DFM and its importance in product design.
  • Analyze the impact of design decisions on manufacturing processes and costs.
  • Develop skills to evaluate and improve product designs for manufacturability.
  • Apply DFM principles in real-world design projects.
