SME: Basic Manufacturing Processes

SME (the Society of Manufacturing Engineers) has a great playlist of Youtube videos that outlines many basic manufacturing processes, and they are all right here for you. Most of the videos are from two to five minutes in length, and get the main points of those processes across to students in an easy to understand format. There are 44 videos in all. Thanks SME!

The best way to search for or find  a particular video is to use Ctrl + F in the browser window and then type in the process you are looking for. It will then jump to the video you are searching for!

CIM-A-Palooza 2017

  Welcome to Cazenovia High School for CAP 2017. Thirty CIM teachers from across this great state getting together to share their expertise and their passion in Computer Integrated Manufacturing.
The goal of CIM-A-Palooza is to walk away with a better understanding of what kind of high-tech manufacturing takes place locally (Tour of Marquardt), and a high interest, low cost project to share with your students in your classroom. This project will utilize CNC machines, laser cutters and other manufacturing techniques including  finishing, cutting, sanding, soldering, and assembly.
CAP 2017
Special thanks to Marquardt Switches and SME Chapter 19 & Jim Maniccia for all they have done to make this a great opportunity for all of us.

Project Idea: USB Powered LED Sign

All files for this project are attached in a zip file at the link below. These files include:
  • All inventor part files: tweak to your heart’s content
  • DWG Files to check tolerances
  • STL  files for a 3D Printer
  • Laser files for the cover & Sign
  • Various pictures to help with assembly

IntroductionSign night

After doing an expensive LED light up sign project last year (with a grant) with my CIM students, I was looking for a low cost alternative. In comes Scott Tobias, new CIM master teacher from Maryland. Thanks Scott for the great idea! You can make these signs for less than $3.00 apiece, depending on what you make the base out of. We 3D printed them at UK with an Affinia printer, as they were prototypes, but they could easily be CNC’d from Wax, Wood, or Renshape.

Parts List

The resistors are $0.05, the cable about $1.50 per end (cut the cable in half to make two!) and the LED’s about $0.50 each. That means the guts are only about $2.00 each!  Great deal, and your students will love how the LED’s fade through all the colors of the rainbow, and you will love how it does it automatically, because it is built into the chip!  NO PROGRAMMING or COSTLY MICROCONTROLLERS. Thanks AdaFruit! Video of how it works HERE.

  1. Build the base. CNC or 3D print. Try to make sure that the LED comes in contact with the acrylic sign. Please see the enclosed Inventor Section view file for the dimensions and constraints. Also be sure to leave room in the base for all of the electronics.
  2. Design and build the sign. The more angles the better, as it will show off the light. Be sure to take into account the tolerance fit between the slot and the plastic. MEASURE the acrylic. It is NEVER really 0.125″!
  3. When engraving the sign, the deeper the engraving, the better it looks. Invert the text and print on the back!
  4. Assemble the parts. Sign into base, wire through side, Hot glue the led into slot,  THEN solder!
  5. Solder the cathode, short leg of LED, to the 68Ω resistor.
  6. Solder the resistor to the BLACK wire of the USB cable.
  7. Solder the RED wire to the other side of the LED. Do NOT solder the green or white wires; do not even strip them!
  8. When soldering, you could use heat shrink tube to prevent short circuits.
  9. Insert the cover into the base. We cut the cover out of  the same acrylic we made the sign out of, and just made it 0.005″ bigger in Inventor, and pressed it in. The hole in the bottom is there to pry it out if necessary.

Example Factories

Question:

Do you have any sample factories I can show my students to get them excited?

Solution:

Sure do…. see the links below!  Be sure to send us any that you and your students do… we would love to feature them here!

CalPoly’s 2015 Factory that Assembles the lid to a container that was built in the previous unit of the CIM course.

That’s right…. CalPoly built TWO factories this year! This one does a powder coating operation on a metal part.
