Class Schedule:

MW 6:30 – 7:50 PM, Room: NTDP B155

Lab attendance is not mandatory at the time you signed up for. The lab sections merely provide groups with a common meeting time and facilities that might be needed for lab assignment completion. Teams are free to meet outside of these scheduled times if desired.

Textbooks:

The majority of the needed course material will be presented through handouts and presentations in class.

An optional textbook is listed below. All tests are expected to be online, so textbooks can be shared usage.

Principles of Modern Manufacturing, 5th Edition

Author: Mikell P. Groover

Catalog Course Description:

This course covers primarily manufacturing process, capabilities, analysis and economics. Selection of manufacturing processes is related to the material selection and properties, technical requirements, production volume and scale. Traditional and non-traditional manufacturing processes are covered, as well as, process selection criteria. Design guidelines for various manufacturing methods are covered such as material removal, forming, casting, welding, forging, injection molding, plastic forming and additive manufacturing (3D printing).

Prerequite: ENGR 2332 (Mechanics of Materials) and ENGR 3450 (Engineering Materials)

Student Learning Objectives:

This class will address the following outcomes:

1.  Describe and develop basic theory encountered in the discipline of material science and manufacturing processes.

2.  Develop the ability to properly assess the capabilities, limitations and potentials of manufacturing processes and their competitive aspects.

3.  Describe new developments in materials, production methods, and computer integration of both technological and managerial activities in manufacturing.

4.  Define, evaluate and select appropriate materials for design and manufacturing.

5.  Apply computer aided manufacturing techniques.

Course Topics:

·  Basic materials and manufacturing concepts

·  Material removal processes (metallic and non-metallic)

·  Material forming processes (metallic and non-metallic)

·  Joining processes

·  Assembly processes

·  Electro-mechanical assembly processes

Lab Assignments:

Lab assignments will consist of industry tours/interviews with a corresponding report from student 3-4 member teams. Student teams are expected to contact prospective companies and coordinate ALL aspects of the industry tours on their own. All team members must attend the industry tour and participate in the team report of the tour to receive full credit. As a representative of UNT, each student should conduct themselves in a professional manner at all times. All members of the small group will receive the same grade unless there is evidence of lacking or non-participation from one or more of the members.

There will be 3 required industry tours for each small group. More information will be presented on the requirements of the industry interview/report.

There will be a lab assignment for each individual involving the creation of a 3D model and then printing your design on a 3D printer. The modeling will be of a drawer handle and will include your initials in the design. Any 3D modeling software that can export a .stl file can be used for your design. The objective is not to be burdensome, but to help you through the complete process of making a 3D model of your design. Additional information will be presented for the requirements of the project. Due to capacity and volume limitations of the 3D printer the due dates will be staggered.

Exams:

Exams will be given to test your comprehension of the material presented in the lectures, in assigned reading assignments, homework and lab assignments. Tests are planned to be open book, open note and given electronically through Blackboard. You will need internet access on a computer to complete the tests. Students will be given a window of opportunity (like 48 hours) to complete the exam online outside of class time. Books can be shared, but no notes or other material is allowed to be shared. Test questions and answers are randomized for each student by the Blackboard program.

Since the exams are multiple choice, true/false, calculations, etc. there is no partial credit. Exam questions that are incorrect by many students will be reviewed for accuracy and fairness. There will be no final exam for this course.

Class Attendance / Participation:

We will be performing a number of demonstrations in class, so class attendance / participation will be a significant part of your grade. A paper or electronic sign-in sheet will be used at each class to track attendance. Please be sure to physically (or electronically) sign the attendance sheet each week to get credit. The attendance sheet may be taken up after the first 20 minutes of class, so if you are late you *may* not be allowed to get credit for attending. Since the class time is close to rush hour traffic times, some allowances may be made for periodic traffic delays; however, late arrival trends are not acceptable.

Disclaimer:

The course schedule, content and assignments are subject to modification when required as the course progresses. If a change will be made, students will be notified ahead of time. We cover upcoming assignments / tests / class deliverables so the best way to stay up to date is to attend class.

Communication:

Your official UNT email should be used for this course. The instructor and other students will contact you via the UNT email system. You must make sure to check your UNT account to make sure you receive all the course information. Blackboard will also be used in this class. Assignments, templates, etc. will be posted online for your convenience. If you have a cell phone, you may be able to configure your phone to allow receive Blackboard messages, which is very convenient. Any last minute changes to daily schedule (such as class cancellation) is communicated by Blackboard.

Disability Policy:

All reasonable accommodation will be made to facilitate special needs. If special accommodations are required, the student must first meet with the staff of the Office of Disability Accommodation (ODA), Union Suite 322, (940) 565-4323. After meeting with that office, please contact me to discuss what accommodations will be necessary. For more information, see http://www.unt.edu/oda

Class Policies:

Class assignments are required to be turned in to instructor on Blackboard, unless otherwise specified. Emails will not be accepted except when specifically permitted by the assignment.

The format for the electronic submission must be able to be viewed/read by the instructor. If you provide the assignment in an unacceptable format, you will be asked to redo the format.

Late submissions after the due date, but before the next class date have the grade for that assignment reduced by 50%. Late submissions after the next class date (following week) will not be accepted and the student will receive a zero for that assignment.

Excusable absences are accepted only if the student informs the professor before the event, such as non-reschedulable prior appointments, or after the event, such as illness, medical or other emergencies, within two class periods of the student’s return. In all cases, academic honesty is expected.

Dishonesty:

Any form of dishonesty during the semester will result in a final grade of F for the course and a recommendation for expulsion to the Provost. No exceptions. Please avoid cheating or any other form of misconduct. If you are having personal problems, please come and talk to the instructor.

Inclement Weather:

We will adhere to the UNT notification system or local weather for school closings. However, I do not want anyone traveling in bad road conditions. If school is closed, no need to notify me (I won’t be there either). If UNT is open, but roads are bad where you are, please email or text me and let me know the situation. If there are any assignments due on bad weather days, you can turn in at the next school class date without penalty. Your safety is more important than an assignment.

Characteristics/Expectations of an A Student:

·  All assignments, action items and deliverables are high quality, completed on time and in the format requested.

·  Student attends class, asks questions and participates with enthusiasm.

·  Team and industry meetings are attended and prepared for.

·  Student communicates effectively with team members, instructor and others throughout the semester.

·  Student takes initiative to learn from others outside of class utilizing their knowledge to further understanding (i.e. contacting industry people with pertinent experience to learn from).

·  Student values different perspectives in team members and works to create consensus/decisions.

·  Student is self-motivated and accomplishes tasks without prodding from others.
