🚧 This is very much likely to change - I'm still learning every day!

I used a 500W china spindle for my tests.

Plexiglas (PMMA)

Melts at 160°C (even earlier than your printer's PLA or PETG).

These are the main challenges:

  • Make sure the chips leave the flute so they can't friction weld (dust shoe, compressed air)
  • Finding the highest cutting volume (diameter*speed*attack) while keeping the tool as cool as possible
cutter diameter (mm) speed (mm/min) plunge (mm/min) attack (mm) rpm cooling notes
single-flute 2.0 300 30 0.5 10,000 none Great result, more should be doable!
single-flute 2.0 400 30 0.75 10,000 none Looks good, might be the limit before it shows.
single-flute 3.175 100 50 0.5 10,000 none Looks okay, but seems to be the limit. 300mm/min also tested, PMMA was melting.
single-flute 3.175 80 50 1.0 10,000 none Too much. Melting after a couple of minutes (Attack 2.00 Speed 100 failed miserably with melting)

Cutter diameter of 2.00mm seems to be the most viable method - maybe trying a higher speed is an option?

Engraving

0.5mm deep TBD TBD

Poplar plywood (Pappelsperrholz)

cutter diameter (mm) plunge (mm/min) speed (mm/min) attack (mm) rpm cooling notes
single-flute 2.0 30 300 2.0 10,000 none Great result, more should be doable!
single-flute 2.0 80 500 2.0 10,000 none Great result, more should be doable!
single-flute 3.175 80 500 3.0 10,000 none Too much! Smells burnt!
single-flute 2.0 80 500 3.0 10,000 none Great result, maybe the limit with this setup?

Pine plywood (Kiefersperrholz)

cutter diameter (mm) speed (mm/min) attack (mm) plunge (mm/min) rpm cooling notes
single-flute 2.0 400 2.0 100 10,000 none Works out fine, more speed should be possible.

OSB (Grobspanplatten)

cutter diameter (mm) speed (mm/min) attack (mm) plunge (mm/min) rpm cooling notes
single-flute 3.175 500 0.75 80 10,000 none Works out fine, more speed should be possible.
single-flute 3.175 555 1.00 127 10,000 none Works out fine, more speed or attack should be possible.
single-flute 3.175 600 2.00 127 10,000 none Works out fine, more speed or attack should be possible.
single-flute 3.175 600 3.05 127 10,000 none I think that's the limit without more cooling or a different spindle. Maybe a little less might be better (2.5/500).
single-flute 3.175 600 2.5 127 10,000 none This might be the best setting with 3.175mm cutter.
single-flute 2.0 600 TBD 127 10,000 none TBD. If no pockets, and cutting depth is not too high, are needed, this might cut faster!
