Abstract
In a laser beam machine comprising: a laser oscillator for generating a laser beam; a machining head for applying the laser beam, as a light spot, to a workpiece mounted on a machining table; and a control unit for controlling the movement of the machining table in an X-Y plane, the laser beam is kept inclined with respect to the workpiece in the machining direction, whereby, when the machining speed is increased, the sticking of dross to the workpiece is suppressed, and the machining speed can be increased accordingly.
