All went ... excellent to my surprise :)
All the feeds and speeds from gwizard work out fine , I had no mist on at the time , just a light (like blow light) air stream at 4 bar.

This is about 1200mm feed, 12-15k rpm? and 2.5 mm deep . 7.9993 mm wide with a 8mm single flute cutter.
Video 2:
00:00 -> 20:00 is finishing the top at like 168 feed (gwizard) very light load. You can see the machine in the reflection of the material.
@23:00 it goes a bit deep ~10mm , 8mm 1F (conventional acc. Gwizard)

I changed the cam after that.
I like the 2F VHM cutters more than the single flute. The 2F allows me to go higher rpm and feed-rate (at least in Gwizard).

The AS196 is a bit low on air volume in my opinion. I would like a harder stream of air.
Adding a 25-50-100 liter external tank with an additional pressure regulator might do the trick.
So the compressor can turn at 4-6bar and filling the tank. The tank can provide 1-2 bar at a bit higher volume than regularly.
Due to the small tank (1.5l?) turning down the pressure regulator from 6 bar to 4 3 2 or 1 does not help to get the volume up.
The machining time is usually so short that a bit bigger tank should solve this problem.
Or I might get a timer and an solenoid that just pulses the air at a higher pressure every few seconds for a short period. Allowing the compressor to catch up and clearing the chips and cooling the bit better.
Anyway.. the machine and cutter works fine. I'm trying some higher feed-rates next weekend to "comply" with the HSM idea.
