ENGR480 Manufacturing Systems Engineering

Spring 2011

Facts:

Instructor: Ralph Stirling
Office: CSP262, 527-2071, ralph.stirling@wallawalla.edu
Class: 10:00 - 10:50AM MWF CSP163, Lab 2-5PM T KRH105
Webpage: http://engr.wallawalla.edu/engr480
Text: Machinery's Handbook, Industrial Press

Important Background:

Basic circuit analysis - if you have forgotten all your Circuits, you may have trouble in this class - review will be in order.
Instrumentation - if you were completely baffled by sensors and signal conditioning, you may have trouble in this class.
Machine Design and Advanced CAD - you will need to design a lot of fixtures and parts for the lab project.
Materials & Processes - if you slept through M&P, you missed important information about machining, which you will need to put into practise in this class.

What you will learn in this course:

What manufacturing is all about.
How to automate the handling and creation of parts.
How to make nifty mechanical widgets that actually do things.
How to use pneumatics.
How to do manual and CNC machining.
How to wire electrical controls.
How to program a PLC to make your machine "think".

What your grade will be based on:

Project - The majority of credit in the class will be based on a large, quarter-long, team lab project. This project will involve the design, fabrication, assembly, programming, wiring, testing, and documenting of an automated production machine. Each team will consist of four students, chosen by me. Each team will be given a grade on their project quality and on their documentation quality, and an individual weighting factor will be applied based on the value of the contribution of each team member.
Memos and Reports - Most of your work will be documented in memo and report format. Grading will be on content, writing quality, and persuasiveness.
Quizzes, homework, and tests - I will use some more traditional forms of evaluation from time to time as needed.
Reading - you will receive 2% extra credit for reading an article each week from a trade magazine or journal, such as Manufacturing Engineering, Design News, Machine Design, Industrial Automation, Modern Machine Shop, or ASME or SME publications. Either print or online editions are acceptable. The CNC Forum on http://www.practicalmachinist.com is also very useful. Just send me an email each week telling me what article you read.
Attendance - Marginal grades may be decided by attendance record. Attendance means full engagement in classroom activities, not just physical presence. Surfing the web, texting on your phone, reading email, or playing solitare does not constitute attendance.
Shop safety - Your grade may be penalized if you cause an accident in the shop or lab that results in injury to anyone or damage to equipment, through negligence, ignorance, or carelessness.
Grade thresholds will be approximately: A: 95%, A-: 90%, B+: 85%, B: 80%, B-: 75%, C+: 70%, C: 65%, C-: 60%, D:55%

Special Considerations:

If you have a learning disability or otherwise need special consideration, please contact the appropriate campus office and have them discuss your needs with me. Since you are all seniors, I assume you will know this process by now if you have such a problem.

Notes on Laboratory and Shop Usage:

CLEAN UP after yourself as soon as you have finished an operation. Put aluminum chips in the barrel marked ALUMINUM, and steel chips in the barrel marked STEEL. Mixed scrap goes in the trash. There are brooms and brushes in both lab and shop, and a shop vacuum available. There may also be a webcam in the shop for me to monitor the condition of the room before and after use.
PUT TOOLS AWAY. Learn where tools are kept and return them when you are done using them each day. Keep materials you are working on under your lab station, but don't hoard.
USE SAFETY EQUIPMENT. Eye shields and ear protectors are provided to help protect you when using machinery. Please use them! Don't wear long sleeves or long hair when working on machines. Clamp work down, remove chuck keys, and use proper feeds and speeds.
ONLY USE MACHINES YOU ARE FAMILIAR WITH. No power tool is to be used until you have been checked out on it first by Erik Biesenthal (lab assistant) or myself. The shop courses taught by the Department of Technology are highly recommended as preparation. You may also have parts fabricated by Technical Support Services.
KEEP E-STOPS PRESSED except when machine or robot is actually in use. This is especially important with Ethernet controlled devices.
