摘要

The paper presents one example successful retrofitting of conventional horizontal milling machine into full automatic control milling machine. In addition to the new way control of machine also kept the old way with manual control of machine as provided with switch selector. The great accuracy of machine tool is performed using compensation of measuring system errors and sag compensation. Installation of computer numerical control compared to conventional control, significantly is improved efficiency and accuracy of machining and safely handling of milling machine.
