Title:
NUMERICAL CONTROL DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/127155
Kind Code:
A1
Abstract:
This numerical control device comprises: a calculation unit that calculates, from a machining program, a start point and an end point of a reciprocating movement of a feed shaft; a control unit that synchronous controls, between the start point and the end point calculated by the calculation unit, a feed movement of the feed shaft and a relative rotational movement between a tool and a workpiece; and a determination unit that determines whether a condition for reversing the feed direction of the feed shaft has been satisfied before the feed shaft reaches the start point or the end point during synchronous control. When the determination unit determines that the condition for reversing the feed direction of the feed shaft has been satisfied, the control unit reveres the feed direction of the feed shaft before the feed shaft reaches the start point, or the end point.
