Abstract

The author considers an accuracy improvement method of lathing with CNC-machine, which is based on the use of the anticipatory signals obtained by means of automatic control system modeling. An anticipatory signal allows to keep constant current in the motor armature circuit at the gear load changing, which is achieved by the cutting depth regulation in the process of lathing. As a result of it elastic deflection stabilizes and lathing accuracy improves.
