Abstract: A laser machine able to effectively satisfy cutting quality required on one side of a cutting spot of a workpiece. The laser machine comprising a machining head configured to emit a laser beam and an assist gas coaxially and non-coaxially; and a data table in which data of a machining condition for cutting a workpiece using the machining head, and a shift amount, by which a center axis of the assist gas is to be shifted from an optical axis of the laser beam in order to make cutting quality on both sides of a cutting line to be different during cutting the workpiece, are stored in associated with each other.

Abstract: A laser machining method able to effectively satisfy cutting quality required on one side of a cutting spot of a workpiece. A laser machining method for cutting a workpiece W by using a machining head able to emit a laser beam and an assist gas coaxially and non-coaxially includes: preparing a machining program specifying, for the workpiece W, a cutting line, and a first region and a second region on both sides of the cutting line where cutting quality requirements are different; and maintaining a state in which a center axis of the assist gas is shifted from an optical axis of the laser beam toward the first region in response to the difference in the cutting quality requirements during the cutting between the first region and the second region along the cutting line in accordance with the machining program.
