    is proposed and is used for the on-line optimal control of the milling process. A BP neural network is used to identify the milling state and to de-termine the optimal cutting inputs. The feedrate is selected as the optimised variable and the milling state is estimated by the measured cutting force.

    Cutting speed. Cutting speed may be defined as the rate at the workpiece surface irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece such as in a turning operation or the speed of the cutter moving past a workpiece such as in a milling operation.
