- TOADMILL: 4 AXIS CNC HOME BUILT MILLING MACHINE
Test cutting 1" 6061 aluminum round stock on the 4th Axis Homemade Milling Machine. Not sure why on Darth Vader's front portion of the helmet had a rougher finish compared to other portions. Didn't hear any chatter. I wonder if it is because of the rotary change of direction. If anyone knows why, shoot off a comment below.

Nice work. The finish on right side of the mouth area appears to be worse than the left. This was probably from the roughing pass, due to the roughing pass being too close to the finish size. Try leaving .020"-.030" stock during roughing, .005"-.010" for semi-roughing, and .002"-.005" for finishing. Could also be backlash in your machine or 4th axis. Easy to check with an indicator. Not sure of your exact setup, just my 2 cents.
Didn't consider that. Thank you!
Can you upload a tutorial on how to do this? I am attempting to do something like this on the 4th axis with bigger stock but my bits plunge too deep because the last operation did not remove those areas and so it overloads the bit and breaks it. Idk how to fix that.
what software did you use
I used VCarve Pro, made by Vectric (www.vectric.com/products/vcarve-pro) to import 3D models (STP, OBJ, STEP, etc) and generate the gcode necessary for the 4th axis. VCarve makes it super easy and is one of the few programs I found that supports the 4th rotary axis.
