Hello all,
I have wanted to make a 3D aluminum cut for a long time. I just could not wrap my brain around pass depth's, cut speeds, and cooling. But I was very conservative and it worked out.
Details:
The Items:
1. I am creating a Blue Moon kegorator for my home and I have wanted these for the sides for some time.
2. The block is 6061 aluminum .75"x22"x25".
Design:
1. Aspire was used to turn the 2D object into the 3D object.
The Cutting Process:
1. I used a .25 end mill upcut bit for the 3D roughing. Cut depth was .004/pass, spindle speed was 9,000rpm, and feed rate was 2" per sec. Clearance was .004 and .1" for the outside border.
2. A .25 ball nose was used for 3D finishing. Cut speed was 2" per second and I used a 4% overlap.
3. WD40 was used as a coolant and you can see my clay wall that contained the liquid from spilling. A gallon of WD40 was $16, and I used it as needed.
