The needs of increase in accuracy, quality and shape complexity of parts manufactured in high-speed equipment is a trend of industry. Problems of ensuring the accuracy at high velocities of machine organs motions are formulated. Machine organs movements accuracy is determined by smoothness of their motions and depends on the smoothness of the trajectory and the law of velocity changing along the trajectory. Algorithm of velocity changing along trajectory using S-curve acceleration-deceleration with smoothly-limited jerk is proposed. Experimental verification of the accuracy CNC machine organs motions at their control with using proposed S-curve algorithm showed a decrease in positioning errors.

Improving the accuracy, reliability and performance of high-speed technological systems is one of the most pressing challenges in modern industry. The process of improvements in machine tools is permanent because of growth in requirements for the parts quality. The HSM process progress may depends on specific characteristics of particular machine. In this connection, there is a need to carry out investigations in real equipment. The possibility of in-process parameters registration using CNC capabilities is considered. Hardware and software solutions are proposed. The software capabilities for data processing, analyzing and displaying a large number of graphs are shown.
