Milling Speed and Feed Calculator CustomPart.Net
Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.
How to Convert RPM to Linear Speed Sciencing
Performing a conversion from RPM to speed in a linear direction involves two steps: first convert the RPM to a standard angular velocity, and then use the formula v = ωr to convert to linear velocity. You divide the figure in RPM by 60, multiply by 2π and then multiply by the radius of the circle.
