Lathe Turning Time Calculator. Calculate the required time for turning lathe operations from the given length of job, feed rate per revolution and revolution of the job per minute using this Lathe turning time calculator.

Milling Speed and Feed Calculator 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.

As you will be able to see in the data below speeds cover a large range of values. Historically machinists have thought that obtaining data for grinding was simply a matter running tests on a given metal, collecting the data, and producing tables with the best feeds and speeds. However efforts to do just that found the subject was far more complex.
