Cusp Height gives an idea of Surface Finish and is most accurate when applied to a flat surface.By reducing the Pitch of Step Over distance Cusp Height is reduced and a finer finish is produced.If a desired Cusp Height is known the appropriate Pitch can be calculated.

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

Jul 18 2005 · My formula just computes the depth to the V of a 60 degee cut.
