Abstract
An NC machine tool is widely employed in manufacturing systems. However, it is impossible to change cutting parameters, such as depth of cut and stepover, to maintain the stable cutting and to avoid the cutting trouble during machining operations, because cutting parameters are determined and coded as NC programs before the machining operation. The digital copy milling system which generates tool paths in real time is developed to solve the problem mentioned above. An NC machine tool associated with the digital copy milling system can perform autonomous and intelligent machining operations unconstrained by NC programs.
