In that same vien of older forums and PM posts;
the go to settings were slow rpm, heavy (thick) cuts, and what have you on the big solid cnc machines. the spindle would snow plow through the material because the machine had brute rigid force. go back further and adaptive clearing wasn’t a thing, HSS was king, etc.
for these little nonrigid machines with router spindles/speeds and small diameter tooling it’s a different ball game. now you got this lil gokart with a shovel on the front for snow plow of a spindle. fast light cuts at the material, not too much - not too little. datron practices are a good idea to keep in mind as opposed to those of old haas/fadals.
SFM will put you in the ball park, but then you have to keep in mind things such as chip thinning and lack of rigidity. it’s all intertwined and the machine capabilities must be accounted for first and foremost.
