Abstract
The feed kinematical linkages of the numerical control machine tools have a direct and decisive influence on the machining accuracy. Their research in closed loop (for the speed and position circuits) is definitely needed, as the transient duty of the linkage participates directly to the path error of the work piece being machined. This paper presentsa theoretical research method of the kinematical linkage as a whole, based on patterns, offering important data on the system performance.
