Another successful aluminum cut

With all my recent upgrades to my MPCNC (video coming soon), I just tried another aluminum part and it was a very satisfying outcome. I’m feeling very good about aluminum now!

  • Op 1: 1/4" (6.35mm) single flute carbide adaptive clearing, 22k RPM, 4.0mm DOC, 600 mm/min, 0.6mm load (trochoidal stepover)
  • Op2a: 1/8" (3.175mm) single flute carbide adaptive clearing, 26k RPM, 3.0mm DOC, 500 mm/min, 0.3mm load
  • Op2b: 1/8" (3.175mm) contour/profile, 26k RPM, 0.4mm DOC, 500 mm/min
  • Op3: 2mm single-flute carbide, bore holes, 26k RPM, ramp 200 mm/min
  • Op4: 1/2" V-bit (45deg) two-flute HSS, 14k RPM, 0.5mm chamfer width, 1.0mm tip offset below edge (this operation was a bit rough, probably should’ve had tip offset lower, so the contact edge of the V-bit would be higher and have higher surface speed)

I don’t have a clip of the adaptive/trochoidal for this part, but here’s a clip for an XYZ plate I milled, same settings. Not the biggest chips, but it’s certainly not dust.

is there a file for the cutting data i can then import to f360?

TBH, I have just been manually putting in all the parameters every time. I kinda have to go through all the dialog tabs anyway for each operation, so it’s not a huge burden, and I have a google doc on the side with all my previous F&S and what worked, and plug it in as I go.

I have put some parameters into tool profiles within F360, but they change not just based on the tool, but the operation and the material. Especially contour vs adaptive clearing in aluminum - 3mm DOC (adaptive) vs 0.4mm DOC (contouring), etc.

I’m sure it could be encapsulated nicely into an export/importable file, but just haven’t tried, yet.

FYI here’s another aluminum success story, with more (probably similar) F&S: Cutting more Aluminum on my MPCNC
