Well, I have a technological reference book, covering all classic machining operations, and there are guidelines how to choose optimal operating parameters, but those are for profesional machines with cooling and everything where in large production tool wear in machining time is very important for final product price . But most of the time home machining is cripled by lack of power and cooling, required to do the job, so if manual say 3000 rpm and you got max of 2800 and then considering that at those rpm your torque will basicaly suck, and rpm will dropped even further down... so we must compromise a little,learn how the machine works optimaly and get more experienced with time, but still good to know the theory behind everything, so that you don't use wood bits for drilling in stone
So if you can't find any data, or books, I'll go to friend and scan needed pages, so tell me what exactly do you need
