Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4.

Sep 24, 2012· Through my experience's, I've found that sticking to the manufacturer's sfpm and cranking up the feed is normally the way to go. I use a lot of 1/8 ball nose end mills @ 12k rpm and upwards of 150 - 200 ipm. Since the finish shouldn't be taking a lot of material off, you still need to produce a chip. Hence the high feedrates.
