I have been watching some of these guys on YouTube using their high dollar mills to machine things. I commonly see where they like to turn a real high RPM and then take the width of cut down considerably while having a full depth of cut. I am not sure if this is what people refer to as "High Efficiency Machining" or not. Part of me wonders if there is really that much of an advantage to machining that way or not. The mill has to perform tons of movements to complete it's too path. I thought "Hey, why not just drop the RPM down to something reasonable and just increase the width of cut instead of trying to make the mill run like a CNC router with a 20,000 rpm spindle?".
