5-Axis Challenge

For the 5-Axis challenge I  decided to CAD, CAM and cut a 20 sided dice or a D20.

I started with the CAD process, I sketched out a pentagon had all the sides meet in the middle above the pentagon. Once I had the first pentagon I started making more below it, connecting them together edge by edge until I had the shape of my die. Once I had the shape with sketches I did construction planes to create the purple sketches around my part to have a sketch in the middle of the dice to see what I'm cutting in my toolpaths.

After the CAD process I moved onto CAM, designing my toolpaths for the Penta Pocket NC, which is a tabletop version of a 5-Axis machine. The only tool I used for the whole process was a 1/8 flat EM. I only used this tool because it was the only tool available to use with this machine and it was the tool that made the most sense because it did it all without needing to be changed out.

After CAD and CAMing my part I got on the pocket NC at clover park and machined it, I had a few errors such as my feeds and speeds being too fast causing the tool to run into my part and stop cutting. To fix these I went into fusion, lowered my feeds from 5000 to 10in per minute, and I changed me speeds from 5000 to 300 feet per minute.

Since I didn't program a part off I had to do it manually with a saw, and then I had to deburr it and get the extra chunk that cutting it had left.

After sawing and deburring my dice it was all fixed up and done!
