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.

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.

What’s the Container Project?

What’s the container project you ask? It’s a project done in CIM class that teaches many different facets of CIM including:
G & M Code, 3D Modelling, Manual machine operations, CNC machining, Secondary processing, Tolerances, Documentation, Mass Production techniques, Assembly operations, Order of operations, Costs of materials, Speeds & feeds….
Just to name a few…  Here’s a short video done by one of my participants at the University of Kentucky Core Training Institute that gives a great visual representation of the steps required to go from start to finish. Thanks to Christopher Townsend, @BCHSEngrTech

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.

MANUFACTURING PROCESS RESEARCH PROJECT IS BORING! GOT A BETTER IDEA?

Question:

Having students write a paper or do a ppt project for manufacturing processes is boring! Do you have a better idea?

reddownloadDOWNLOAD: 2017-mfg-research-project

Solution:

Sure do! How about a manufacturing process brochure? This way students have to do a bit of research, (1 to 2 days) on given material, then post them for other students to see.  I post mine in a hand outs folder on the network.Also included in the activity is a list of topics to choose from.
Electroplate

The brochure is a Publisher template, or a Word template that you give them; after all, this is not about using publisher or software is it?!? Just be sure that students replace all the pictures and text in the template with their own. You’ld be surprised at the number of students who don’t!

 

On the second page of the handout is a rubric to use for scoring, and step three of the project is my favorite! Kids write a multiple choice quiz question, upon which they are evaluated, and then I take all of the electronically submitted questions, put it into a quiz; after editing of course, and then allow the kids to take the quiz “open brochure” style. This means they can look through all the students brochures to get the answers. This way they learn a little bit about ALL the processes, not just theirs!
