Technology teacher Chris Lallier from SUNY Oswego has put together a killer project for teaching basic CNC programming. The project consists of a wooden yo-yo that is engraved, using CNC, on both sides. Students are then able to paint, stain, sand and assemble the project, giving students the opportunity to learn about more manufacturing processes.
Special thanks to Chris Lallier who put it all together with the help of Jim Hanson and myself. Also, a very special thanks to Chuck “The Godfather of CIM” Spangler, who has been doing plastic yo-yo’s for many years!
The Yo-Yo kits, unassembled, are available at Casey’s Wood Products, and cost less than a dollar each if you order 50 or more. The best part is that this is the DELUXE model: with a sleeper string! It was the only place that sold them in smaller lots, and you can buy them individually as well. We looked into plastic ones as well, but they had to be purchased in lots of 250. This would make a great promo for open house as well!
The project consists of a teacher built fixture to hold the halves in your machine, and then provides you, the teacher, with a student driven activity to produce the final product. Also included is a step by step guide on building the fixture, a complete parts list, the Inventor, EdgeCAM, and NC files, as well as student templates.
The whole project, including all the above files, is available here for free for you to use. The file is a .zip file, and just needs to be downloaded, and unzipped, in order for you to use the files.
Chris Lallier is a Student Teacher from SUNY Oswego graduating in December 2011. He is a Technology Education major with a background in residential construction. While working summers with his family construction business he was introduced to CAD home building programs, structural design, manufacturing processes and planning techniques. He was inspired to move into the field of Technology Education so that he could teach others about the topics that he found fascinating. He is currently teaching three college credit courses at Cazenovia High School; Principles of Engineering, Design and Drawing For Production and Computer Integrated Manufacturing. Chris is looking forward to a long and rewarding career of learning and teaching students about all things Technology.
