Just trying to wrap my head around the feeds and speeds topic (again, new at this, so pardon the naivete) and how seriously I need to take this as I am learning my way around my machine. I definitely understand the basic concept and understand that it takes some complex math and calculations to properly set things up manually. I’ve reviewed a couple of the spreadsheet type applications that some folks have posted, but, honestly, still don’t quite get all the variables and still can’t bring myself to understand how to “program in” the various parameters to get to the basics: how fast to plunge, how fast to cut, how deep to cut, how far to step-over, RPM, etc.
So, to my question: Is there a problem with using the F&S settings that are suggested by CC when one sets up his/her toolpaths? They seem to be be based off of the material being selected, the size of the cutter, and the operation being performed, etc. I was thinking that the software was doing some sort of internal calculation and was providing appropriate parameters for F&S when the toolpath was created. Am I off base here, or should I be committing some extra brain cells to more thoroughly understanding how to set F&S manually?
