I just like to give a guy some idea of where to start. I know for my self if I read take lite cut I think less then .010. When I read slow speed I think 300 and down. And thats completely relative to the dude reading it. I totaly discounted alot of bench mills because I kept reading "just take lite cuts" so to me that means that machine can only do .01 at a pass with no stress. And thats a huge misconception but thats my interpretation of the term. This is also why I ask so often what DOC their machine is pulling off with a typical end mill. Not a rougher. Thats important to me if I am buying. Because the terms used are so wide open to ones own conclusions.
That being said, the machine will talk to you, the material and cutter talk, shoot even the coolant or cutting fluid could say something. If you cant hold the part for 10min cause it will burn you that part is talking to you ahahahahahahaha
