Dusty desktop!

Today I spent more time on testing the milling machine. I received a set of mills yesterday and decided to try one of our toolpaths on a piece of MDF.

Here some pics:

Proxxon MF 70 in the office
Ball nosed cutter, ∅ 8mm
The clamping is a little improvised…
Feedrate of 1mm/sec, you can see the cutter clogging up with burnt MDF

I am quite pleased with the results. I think I will try a higher feed rate next, maybe thats a way to avoid the cutter clogging up with burnt MDF. While cutting, something made the programme to loose its position and I had to stop it. I assume MDF is not an ideal material, I assume resin as used in toolmaker’s workshops would be much better.
Finally here’s a little movie. Light conditions were not good and I used my digital camera, so not the greatest quality.

    Are all your computers dusty now?

    Is that really a ball endmill, or is it a burr (many flutes, not a lot of clearance at the center)? Burrs will load up and aren’t really center cutting. Try a 2 flute ball endmill or router bit instead. You should have proper chips coming off.
    Put a shop vac nozzle near the head and suck the chips up while you cut as well.
