Document Type and Number:
WIPO Patent Application WO/2021/251390
Kind Code:
A1
Abstract:
A numerical control device 100, which performs a movement control on a machining tool T through a fixed cycle according to the present invention, comprises: a main control unit 110 which issues a machining instruction to a machining device 10 on the basis of a machining program; a machining program analysis unit 120 which reads ahead and analyzes the machining program; a machining state measurement unit 130 which measures physical quantities indicating the machining state during machining; and a start position determination unit 140 which determines an overlap control start position Po on the basis of the measured physical quantities, wherein the main control unit 110 executes overlap control, when the machining tool T is determined to reach the overlap control start position Po.
