Title:
LASER MACHINING DEVICE AND NUMERICAL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/276115
Kind Code:
A1
Abstract:
A numerical control device for controlling a laser machining device that machines a workpiece by means of a pulse laser emitted from a laser machining head while moving the laser machining head and the workpiece relative to each other, said numerical control device being provided with: a speed command generation unit for generating a speed command for controlling the speed of the relative movement on the basis of a machining program; a laser command generation unit for generating a laser output command value that includes at least the frequency and duty of the pulse laser, in accordance with the speed command; a change rate calculation unit for calculating a period command for the pulse laser on the basis of the frequency, and calculating a change rate of a changed period command changed by a limitation for the performance of the laser machining device; and a speed adjustment unit for using the change rate to adjust the speed command generated by the speed command generation unit.
