COURSE NOTES

 

1.      SAFETY: Please review and thoroughly understand the safety regulations for the Manufacturing Center, Williston 001.

2.      This is a laboratory course.  If you are absent you must get the materials and information you missed from your LAB PARTNERS.  There are multiple sections.  If you wish to see the materials you missed you may attend another section, but you will NOT be credited for attending.

3.      This course is broken into two 6-week components: SolidWorks, and Manufacturing.  After 6 weeks you will rotate to a new section.  All students will receive a composite grade from these components.  The rotation days and faculty will be announced as the switch date approaches. 

4.      If you arrive to class or lab and do not see the electronic attendance sheet I use, it means you arrived late.  You will be marked absent unless you stay at the end of the session and have me change the spreadsheet to mark you as late, rather than absent.

5.      To map the network drive that serves the Manufacturing Center open a   File Explorer, right click on This PC and click as shown below on Map network drive . . .

Add the drive by typing   \\drive.wit.edu\manufacturing
When completed you will see all the information on the drive.

 

LABORATORY NOTES

 

1.      Always have at the ready your notebook. I recommend a cheapy spiral graph paper notebook from Staples ($0.99)

2.      A calculator is required.

3.      Please always observe all safety regulations.

4.      Be sure to view the welding video linked on the GMAW tensile test lab activity.  You must use either FireFox or Internet Explorer to view the video.  Chrome will not work.

5.      Please have your safety glasses with you at all times. Each time I lend you a pair, or ask you to put them on, reduces your course participation grade.  I will not be the “safety glasses cop”: you will simply receive a lower lab grade.

6.      You are responsible for a thorough clean-up after using any equipment.

7.      There are three “shut-down” emergency buttons on the walls of the lab.  If you see someone in trouble on a machine hit the EMERGENCY STOP button.  This will stop the spindles from turning.  They are a no-harm-no-foul button.

 

LAB GRADING CRITERIA

 

It is my hope that you will find the laboratory projects beneficial in your academic and professional efforts.  Much of the grade for the course is taken from these activities.  It is my experience that students fall somewhere within three categories in the laboratory:

  1. Lacking preparation and confidence the group wants to spend a lot of time with me directly answering each question as it arises. Basically, making me their lab partner. This is not practical or useful at all, and this lab team usually ends up with very poor lab grades.
  2. The team that does their work, and then leaves the lab, or asks me to post more material so that they may move ahead, on their own, at an accelerated pace. This generally ends up with satisfactory lab grades, but not outstanding.
  3. Having completed their work, and helped others in the lab group, this lab group looks to assist other groups with problems they are having. It seems they are around the lab a lot, and are adding to their technical skills, as well as communication, leadership, and team building skills. These students always end up with the highest possible lab grades.
