MAE 742 Mechanical Design for Assembly
 

 

The objective of this course is to provide students with the knowledge, methodologies, and practice to optimize the design of mechanical products for ease of assembly in manufacturing. What the student will learn will include: (1) why Design for Assembly (DFA) is important, (2) how to characterize and describe assembly, (3) what ideal assembly systems are in use today, (4) how to apply DFA principles to mechanical product design, (5) how to design parts to facilitate assembly, (6) how to analyze designs in terms of DFA and redesign to improve assembly, (7) how to quantify and compare improvements in assembly resulting from design revisions and (8) factors affecting the mechanical feeding of small parts. 3 credit hours.

 
       

Prerequisite
 

Graduate standing in engineering or consent of instructor.

Course Presentation
 

This course will be delivered in a hybrid asynchronous fashion. All regular lecture material (text, audio, graphics, interactive exercises, and off-line assignments) will be provided on CD-ROMs for access by each student at his or her convenience within a prescribed schedule of progress over the semester. The instructor will meet formally with the on-campus students only once each week for the entire course. Recordings of class meeting will be provided to off –campus students by the Internet or on CD-ROMs. EOL students are encouraged to e-mail questions concerning the weekly course material. Those questions will be answered during the weekly videotaping of the on-campus class. The purpose of these meetings will be to monitor and assist with the out-of-class progress of the students. This will include answering the local and distant student questions and discussing the CD-ROM delivered materials, reviewing off-line assignments and other homework, administering short quizzes as well as a mid-term and final exam, and providing consultation for end of course project.

Registration
 

All students must register through the Engineering Online registration site at http://www.ncsu.edu/project/engonline/index.php. You do not have to be admitted to a degree program to enroll in an online course. However, you must have completed a bachelor’s degree in engineering, computer science, or related area from an accredited institution. Full-time, employed individuals are limited to enrollment in two graduate courses for each semester. On-campus degree seeking students must have approval from their Director of Graduate Programs to register for an Engineering Online course.
