  6. Text: Mechanical Assemblies by Daniel Whitney

Important Background Material:

  1. Basic circuit analysis - if you have forgotten all your Circuits, you may have some trouble in this course. Review is in order.
  2. Instrumentation - if your were completely baffled by sensors and signal conditioning, you may have trouble in this class.
  3. Machine design and Advanced CAD - you will need to design a lot of fixtures and parts for the lab project.

What you will learn in this course:

What your grade will be based on:

  1. Project - The majority of credit in the class will be based on a large, quarter-long, team lab project. This project will involve design, fabrication, assembly, programming, wiring, testing, and documenting 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 individual contribution of each team member.
  2. Memos and reports - Most of your work will be documented in memo and report format. Grading will be on content, writing quality, and persuasiveness.
  3. Lab notebook - keep a record of your lab and shop work in a bound notebook. Also a good place to jot down notes and ideas for designs.
  4. Quizzes, homework, and tests - I will use some more traditional forms of evaluation from time to time as needed.
  5. 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, or ASME or SME publications. These may be print or online editions. Just send me an email each week telling me what article you read.
  6. Attendance - Marginal grades may be decided by attendance record. Attendance means not just physical presence, but engagement in the classroom activities. Surfing the web, reading email, or playing solitare on your laptop is not attendance.
  7. 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.
  8. 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:

  1. 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. There are shop vacuums, brooms, and brushes in both the lab and the shop. Teams will have a rotating schedule to give the Haas TM-1 mill and the shop a complete cleaning once a week. There will also be a webcam in the shop for me to monitor the condition of the room before and after use.
  2. PUT TOOLS AWAY. Each team has a tool cabinet for the most basic tools. You may also put parts you are machining in your tool drawers so they don't end up in someone elses fixture. Don't hog shared tools or raw materials in your drawers though!
  3. USE SAFETY EQUIPMENT. Eye shields, ear protectors, gloves and other measures are provided to protect you when using machinery. Please use them. Clamp work down, remove chuck keys, and use proper feeds and speeds.
  4. ONLY USE MACHINES YOU ARE FAMILIAR WITH. No power tool is to be used until you have been checked out on it first by Peter Scheidler (lab assistant), Tim Rasmussen (lab assistant) or myself. The shop courses taught by the Department of Technology are highly recommended as preparation. You also may have parts fabricated by Technical Support Services.
