Abstract
In a three-dimensional laser beam machine having a head structure in which a processing point is not moved when a rotation axis and an attitude axis are rotated, the machine has: means for storing information of current angles of the rotation axis and the attitude axis, and calculating a nozzle direction vector from the angles; means for, based on the nozzle direction vector, determining angles of a nozzle in a vertical direction and a horizontal direction consisting of a Z-axis of an orthogonal coordinate system; and means for displaying the determined nozzle angles.
