You only have to get familiar with the feed rates, which I believe is a self-taught thing. Don't go with feeds and speeds tooling manufactures tell you, its WAY to fast for normal use, just go with what you see as a good feed rate. It’s not hard to get used to, just do a few sample cuts. Climb cuts are better with cnc because of ball screws vs. acme screws, cause ball screws don’t have backlash, so you wont get the big KA-POW for climb milling. Don’t worry, if you know manual machining, cnc is easy. I am in Grand Rapids Mi. so we must be neighbors.
