Speeds and Feeds Calculator (Milling, Turning, Drilling)

RPM diameter – The diameter where the cutting speed requires the spindle to rotate at the maximum allowed speed. Below this diameter, the cutting speed gradually decreases, and the RPM stays constant. Full speed cut – The calculated displays the percentage of time operated with the calculated cutting speed before it is "clamped" by the RPM.

Mill Critical Speed Calculation

— Three different disc sizes of equal proportion were used. The mill was rotated at 63% of the critical speed. The position of the balls at the end of five revolutions is shown in Figure 2. It is seen that, using a low coefficient of friction at the walls, balls tend to flow down the surface of the charge, and a "toe" begins to form.
