This makes no sense to me but i have only cut 10 parts. Usually 5 are OK

Quite likely -- - - nope!

A high quality cutter has a sweet spot for usage - - - - you're cutting wood
by the sound of it so I've got no ideas as to speeds/feeds. If you were
asking for metals - - - - I'd have some suggestions.

There are cutters out there that deliver scary results - - - - think
like liters of
Aluminum chip in no time flat - - - - takes some serious power and
rigidity but doable. Are many people using this level of production - - - nope!

So - - - - what are you cutting?
How rigid is your workholding/machine?

More later!

You can't really do light cuts in wood (like a 'spring cut' in metal) because it'll splinter etc, maybe that's what was happening so the deeper cut from the higher feed rate helps with that.

You could always put the feed rate back to what it was and crank up the cutter speed and see what it does, if only for your own amusement.

redoing the whole 4th axis. i did get it tighter increasing the pressure

improved finish a little.

i am cutting wood, i have no problem with metal or plastic. wood is a
bitch. i ordered some better cutters and will see what they do.

Check the place you're ordering from - - - they might offer some
parameters.

I'd say you've manage to find a decent feed & speed for that particular type of wood, so all good I guess.

Terrible stuff wood, just so inconsistent. Should be banned, I think I'll write to my local member and demand they sort it out.

(From what I hear you can't buy any wood in the US anyways, so job done!)
