The article deals with a developed mathematical model of automatic control system in metal-cutting machine cross-feed providing higher accuracy of workpiece machining. The result is achieved by the introduction of an additional correcting signal into the gear control system, representing an error caused by the spindle eccentricity. The eccentricity error is functionally connected with cutting force and upon its change with the model help a correcting signal is formed supporting a controlled value after the transient process completion.
