Homework

  • Our homework was to make something BIG!!!!! Actually, the week is called "Computer Controlled Machining", so we have to use a program to design something big and have the ShopBot cut it out. My plan is to make a GIANT Tic-Tac-Toe game for my 3rd graders to use as a learning game to review concepts....If you get the question right, you get to put an X or O on the board. They can also play with them during indoor recess.

  • I am going to make the O's gears to represent the design process that we use and because the gear is a symbol for the new STEM school we're opening.



    Challenges

  • My biggest challenge this week was learning to draw the gear in Corel. I started by watching and watching and rewatching a YouTube video that showed a guy AKA "Corel Trickster" drawing a gear in a minute and 44 seconds! The problem with the video was that it didn't have any sound, so it was hard to follow his steps. I looked for other tutorials, but this guy's was the best looking gear and seemed least complicated. Hmmmm.....

    Designing

  • I designed my giant Tic-Tac-Toe game in Corel Draw.




















    Cutting

    With plywood as my material, I used a 0.25" flat endmill, speed of 12,000 rpm, and a feed rate of 2 in/min for the ShopBot. The plunge rate was 30.
