Improvement of machining efficiency in aviation greatly depends on high-speed milling technology application. Necessity to carry out investigations of algorithms and processes in CNC machines on real equipment is stipulated by dependence of high-speed processing efficiency from parameters of certain equipment. Hardware-software complex integrated with CNC system based on personal computer for recording the parameters in processing equipment and internal CNC variables with CNC control loop frequency is developed. Applications of the system for designing an equipment control algorithm by step motion from operator console, feed prediction algorithm, software regulator optimization, investigations of energy and vibrations at high-speed milling are shown.

Key words: high-speed milling, CNC, positioning accuracy of machine organs, positioning error.
