Cutting Speed

The surface speed of the workpiece in a lathe or a rotating cutter.

The cutting speed as a function of rotational frequency is:


v = cutting speed [ms-1]
a = part or cutting tool radius [m]
f = part or cutting tool rotational frequency [Hz]
N = part or cutting tool rotational speed [rpm]

Enter radius, a and speed in rpm and press calculate.

or rotational speed and cutting speed to calculate a.

Cutting speed [rpm] versus Part/Tool Diameter [mm]
