• Difference Between Cutting Speed and Cutting Velocity

    Difference Between Cutting Speed and Cutting Velocity

    Cutting speed is basically the rotational speed of either workpiece or cutting tool (whichever is rotating, based on the machining operation). It is measured by the unit revolution per minute (rpm) and usually designated by N. On the other hand, cutting velocity is the tangential velocity of either rotating workpiece or rotating cutting tool.
