NUMERICAL CONTROLLER CAPABLE OF MACHINING CONDITION CONTROL BASED ON POSTURE

摘要

A numerical controller controls a laser beam machine in accordance with a program and performs three-dimensional laser beam machining on a workpiece. The numerical controller obtains a ratio between a machining speed at an upper surface of the workpiece and a machining speed at a lower surface of the workpiece on the basis of a posture of a nozzle of the laser beam machine and changes a machining condition specified by the program on the basis of the obtained ratio.
