CNCing Hello Kitty’s Bow | ENGI 210: Prototyping and Fabrication

Hello everyone, these are my bows for the CNC beginner homework!! Very Special BOWS To begin I used the noun project to look up the svg I wanted to print. After being satisfied with my bow, I went to CarbideCreate to edit the svg. Upon finding two scrap pieces of wood, I measured the thickness, length, and width to follow all the steps appropriately. I used the contour line to determine which lines I wanted to be fully carved out, and then a toolpath to carve out areas of the bow to 0.01 depth thickness. I followed all the appropriate steps with probing using the corner calibration piece and measuring the thickness of the #102 1/8th in. end mill I was going to use, and making sure I had two tabs.

After securing my wooden piece down to the board with double sided tape, I was ready to begin. However, I would later realize how important it is to make sure that my wooden pieces are so so so secure as when the machine is cutting, it will vibrate/loosen the piece, I had to retry twice as my pieces kept moving mid cut. (maybe I just wasn’t strong enough to push it down those first two times).

Once finished, there was still maybe 2/16th in left of the wood at the bottom, so i used the band saw to finish cutting off the box from slab of wood. I post processed with a wooden shaver and sandpaper, for a smooth round edges. I then decided to spray paint the bow white, and then add a pink layer of epoxy to the center to make everything really nice. Since my bottom of my pieces werent the best, I used some felt to cover up my errors.
