When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated. Then if the tooth load for the cutter is know, and the number of teeth, the feed rate ...

The Formula derivation ends up as follow: Critical Speed is: N c =76.6(D 0.5). where: N c is the critical speed,in revolutions per minute,; D is the mill effective inside diameter, in feet.; Example: a mill measuring 11'0" diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11^0.5 = 23.1 rpm

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. As can be seen from the ...
