Don't worry aRM the cutting speeds, RPM, feed rates, depth of cut etc can be challenging to get a handle on and I struggle with them and really have to concentrate. On my lathe it really is trial and error, as my top speed is lackluster to say the least and my auto feed isn't working (missing actually). I do however look at the DOC range for the inserts and then try to find something in there that works for me. However, I'm only a hobby machinist so I have time to experiment.
Now that I have my mill up and running (albeit with some jobs still to do), I'm finding myself looking at these parameters a little more closely, as I am using HSS mills (to begin with), as they are cheaper to break than carbide ones
But HSS needs to run in a certain window otherwise I will burn them up or rub them blunt.
I'm finding the Walter Machining Calculator to be very useful but you have to know the data that it asks for. Some insert manufacturers make this fully available and some do not. I know that Ken has linked to it before but I may as well link to it here, so that you (or anyone else) doesn't have to go searching. It is available in the Innovative App & Software Solutions section.
