Title:
NUMERICAL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/045292
Kind Code:
A1
Abstract:
A numerical control device (1) comprises: a storage unit (11) that stores a processing program for carrying out two or more times a fixed cycle including a first operation for positioning a hole-formation position in a workpiece (4) with respect to a tool (2), a second operation for moving the tool (2) from the return point to the hole bottom point, and a third operation for moving the tool (2) from the hole bottom point to the return point; a control unit (12) that controls relative movements of the tool (2) and the workpiece (4) on the basis of the processing program, starts the second operation before the completion of the first operation, and starts the first operation of the next fixed cycle before the completion of the third operation to cause the tool (2) to move along a curved path; a distance calculation unit (13) that calculates a retraction distance from the workpiece (4) to the return point; and a curve amount calculation unit (14) that reads, from the processing program, a positioning command for a hole-formation position in a next fixed cycle before the third operation is started and that calculates the curve amount of the curved path in the next fixed cycle on the basis of the positioning command and the retraction distance.
