FIELD: electricity.
SUBSTANCE: self-teaching principle with ensured minimum systematic shape errors on part-to-part basis is implemented in the device, at that accidental errors occurring in result of the above zones shifting are minimised. The effect is attained by switching off integral component in cutting tool position regulator in non-cutting zones.
EFFECT: improved accuracy of lathe machining for serial noncircular parts in conditions of random shifting on part-to-part basis in intermittent cutting zones.
