Course Description:

 

An overview of manufacturing processes with the objective of establishing the processes most appropriate to the characteristics and production requirements of the product. Metallurgy is briefly reviewed as a basis for material processing. Many conventional methods of fabrication are covered. Design for manufacturing and assembly techniques will be studied along with assembly methods and flow. Clean rooms and electronic assembly is also covered. Students unfamiliar with manufacturing processes will need to do independent study to determine all of the processes available.
   
Course Objectives: To review and discuss the various manufacturing processes that are available and relate to their characteristics, cost and volume needs, and design requirements. Discuss the design to production transition process (concurrent engineering) and its importance. Discuss processes for mechanical and electronic assemblies Have the ability to carry out the analysis for efficient assembly design.
   
Learning Outcomes: Upon successfully completing this course the student will be able to:

1.      Explain the basic concepts of the structure of iron and steel and its heat treatment.

2.      Able to use a selection criterion for identifying the appropriate process based on shape criteria and material requirements.(SE4, MS6)

3.      Understand the following near net shape processes and be able to evaluate for functional and cost trade offs: Casting, forging, extrusion, powder metallurgy, and injection molding. (SE5, MS6)

4.      Understand the various cutting, forming and machining processes and be able to evaluate for functional and cost trade offs: press-work, welding and joining. (SE4, MS6)

5.      Understand the unconventional material removal processes of: EDM, EDWC, Laser Beam, Electron Beam, Electrochemical machining, chemical milling, Ultrasonic machining, Abrasive jet machining and water jet cutting. (SE4, MS6)

6.      Discuss the key features and manufacturability and environmental trade offs in selection of plating and corrosion protection films, plating and anodizing. (SE3)

7.      Have an understanding of the basics of electronic assembly and design.(SE3)

8.      Understand the importance of Design To Production Transition. (SE3)

9.      Able to demonstrate appropriate assembly techniques.(SE5)

10.  Able to apply principles of Design to Manufacturing and Assembly (DFMA) and analyze an assembly using Boothroyd and Dewhurst methodology. (SE5, MS6)

Note: the designators in parentheses refer to the learning outcomes of the master degrees.( SE = MMSE, MS = MSMS)

   
Course Methodology: The course will start with metal production, heat treatment, metallurgy and testing as a base for the process descriptions and applications. Selected chapters of the course text will be used as a guide augmented by lectures and student presentations. The course will review conventional and non-conventional processes for cutting, joining and forming, clean room use, and mechanical and electronic assembly. (Note- the metallurgy and metal production processes are a review and we will move quickly, students that need more understanding should read the textbook in more detail and use other resources to obtain basic knowledge.). The videotapes will be used as time permits. The reading assignments are designed to provide background to the weekly subjects. They are designated by a chapter and page range. If further designated-skim: only a brief review of the text is required.

Independent research should be undertaken to gain in-depth knowledge of particular processes.

   
Associated Courses: ETLS 773 Principles of Micro-Electro Mechanical Systems (MEMS) Product  Development
ETLS 771 Materials Engineering
   
Major Assignments:

1. There will be a final paper due in the tenth week of class (5 point penalty per week or part of week late). This paper should be a case study/research project on a manufacturing process of your choosing (with approval of the instructor). It should include: a description of process, theory, data, comparison of costs, future improvements, projections, applications, etc. The paper should be written in a scholarly way with research into literature and case histories relevant to the topics being discussed not just a regurgitation of existing literature (approximately 10 pages).

2. Each person will be expected to produce a class report for presentation in class. This paper should preferably give the author's personal experience with a process. Oral presentations will be a maximum of 10 minutes. A written report of approximately 4 pages in length is also required for distribution to all class members.  This report is to include a bibliography plus copies of any overheads, or Power Point material used in the oral presentation.           Note; Presentations will be cut off at the 10 minute point (with a one minute warning).

3. There will be a take-home midterm exam on the sixth session covering the subject matter of the first half of the class. (The content will be taken from the assigned readings, Lecture notes and class sessions) The answers will be collected on the seventh week. Answers not returned on this date without prior agreement will grade an "F" - no exceptions.

4. There will be a final exam on the eleventh session covering the second half of the course. Results will be returned on the twelfth session.

Academic Integrity: All students are expected to understand and follow the University of St Thomas policies on Academic Integrity. These are described at:
http://www.stthomas.edu/engineering/graduate/policies/
 

Exams: Exams are one of the instruments used to evaluate the knowledge gained by an individual student of the class subject matter, and the progress towards meeting the outcomes of the class and the degree.  To this end all exams (in class or take home) are intended to represent the effort of the individual and not a group effort unless specifically stated otherwise.

Plagiarism:  Plagiarism is not allowed and will result in a minimum of an ‘F’ for the work. For your reference I have reproduced part of the relevant section of the Student handbook under Academic integrity and dishonesty:

Plagiarism - The deliberate adoption or reproduction of ideas or words or statements of another person as one's own without acknowledgment. In every instance, you also must formally acknowledge the written source from which you took the material. (This includes material taken from the World Wide Web and other Internet sources.)

   
Students with Disabilities Qualified students with documented disabilities who may need classroom accommodations should make an appointment with the Enhancement Program – Disability Services office during the first two weeks of the semester.  Appointments can be made by calling 651-962-6315 or in person in O’Shaughnessy Educational Center, room 119.
   
Attendance
Policy:
Students are expected to attend all class sessions. Circumstances which prevent attendance will be honored up to two instances. Absences in excess of two times may result in a lower grade for the course. Contact the instructor when a special situation arises. All absences require that the instructor be informed in advance. Breeze will be available for people unable to attend but is not intended to be used for regular distance learning.
   
 Breeze   We will be using ‘Breeze’ during classes.  This is a program that records the classroom audio and Power point presentations. This will enable people unable to attend a session to sign in and participate in the class on their PC. It enables an audio connection with the right connections or live write ins during class.  After the class session the Breeze recording will be made available through Blackboard
   
Copyright: Permission is granted by the instructor for the future use and/or reproduction by the student of any material presented during the course.                                                                                Permission is assumed from the student for the future use and/or reproduction (by the instructor or other students attending the course) of the contents of any paper submitted (written or oral) during the course unless written notification to the contrary is received prior to the end of the course.
