Experiences in Designing a Design for Manufacturing (DFM) Course Dr. Richard Jerz, Dr. Gary Fischer St. Ambrose University / The University of Iowa

Abstract

Mechanical Engineering and Industrial Engineering faculty at The University of Iowa agreed to implement a required undergraduate course for each curriculum that will give students an understanding of basic design principles and manufacturing processes. The new course is called, Design for Manufacturing (DFM). The course goals include giving students the opportunity to develop an understanding of the fundamentals of design, engineering graphics, and manufacturing processes. Topics covered include introduction to design, manufacturing, and design for manufacturing; phases of a product life cycle; product design process; introduction to engineering drawing standards and graphics; computer-aided design (CAD) modeling; and various manufacturing processes. The course includes "hands-on" CAD/CAM and computer numeric control (CNC) machining projects.

This paper discusses experiences in designing and delivering the DFM course. Among the issues that had to be resolved were what topics should be included; what book or books should be used; what software should be used; what kind of laboratory experience should be included; and what resource materials should be chosen for the course?

I. Introduction

The College of Engineering at The University of Iowa has had a Manufacturing Processes course for more than forty years. The course was originally developed and taught in the Mechanical Engineering (ME) Department, but through a reorganization of the College, the course was transferred to the Industrial Engineering (IE) Department. In the spring of 2002, the two departments were joined into one, the Mechanical and Industrial Engineering (MIE) Department. One of the early faculty actions in the new Department was to create a new course, Design for Manufacturing (DFM), that would be a required course for both ME and IE undergraduates. The course was intended to replace the Manufacturing Processes course required for IE’s. The plan was to offer the new DFM course in Spring 2004.

Product design and manufacturing topics were also covered in another IE course called Manufacturing Systems. Initially, the primary emphasis for this course was CAD/CAM methods and 3D solids modeling. The CAD product, Pro/ENGINEER®, was used to give the students hands-on laboratory experience. Each student designed a rotational part and machined it on the Department’s CNC lathe. In 2002, the Manufacturing Systems course focus was changed to include contemporary manufacturing and production system topics, and it was believed CAD/CAM topics more logically fit into the new DFM course. To appreciate CAD/CAM fully, it was believed that the DFM course should also contain lectures on engineering graphics, which Proceedings of the 2005 American Society for Engineering Education Annual Conference & Exposition Copyright 2005, American Society for Engineering Education
