Abstract

A sharp corner judgment means judges as to whether a corner of cut shape in a workpiece is a sharp corner is not on the basis of a machining program. When the corner is regarded as the sharp corner, an additional locus producing means for producing sharp corner produces an additional locus for producing sharp corner when machining on the corner regarded as the sharp corner, and a sharp corner machining execution means executes machining on the corner on the basis of the produced additional locus for producing sharp corner. Then, the additional locus for producing sharp corner can be automatically produced for the sharp corner so as to execute machining.

Dependent claims

A laser beam machine,

a radiating means for radiating laser beam on a workpiece to be cut;
a means for moving and driving, for moving and driving said radiating means at predetermined feed speed;
a machining execution means for moving and driving said radiating means through said means for moving and driving on the basis of a movement instruction instructed by a machining program;
a sharp corner judgment means for judging as to whether a corner of cut shape in said workpiece is a sharp corner or not on the basis of said machining program;
additional locus producing means for producing sharp corner, for producing additional locus for producing sharp corner when machining a corner which is judged as said sharp corner by said sharp corner judgment means;
and
a sharp corner machining execution means for machining said corner judged as said sharp corner on the basis of said additional locus for producing sharp corner produced by said additional locus producing means for producing sharp corner.
