Calculating Mill Drive RPMs: Is Your Mill Up to Speed? By Robert A. Sladky Vice President Tube Mill Engineering Many “W” style mills that have the ability to shim up the bottom driven shafts in each section to maintain metal line after tooling is reworked, and are many times also equipped with a individual motor drive in each of the three sections as illustrated below.

So our task is to find where a curve goes from concave upward to concave downward (or vice versa). Calculus. Derivatives help us! The derivative of a function gives the slope. The second derivative tells us if the slope increases or decreases. When the second derivative is positive, the function is concave upward.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
