A machining condition modification definition statement (11b) is created, in an automatic programming language, specifying a machining condition modification interval at a corner portion of a part and machining conditions in this interval. A figure definition statement (11a) and a motion definition statement (11c) are created in accordance with part shape without taking the machining condition modification interval and machining conditions into consideration. When these definition statements are converted into an NC part program for laser machining executable by an NC unit, the corner portion of the part is divided into two or more machining condition modification intervals in accordance with the machining condition modification definition statement, and an NC part program for laser machining is created in such a manner that the set machining conditions will prevail in each of the intervals.

A method of creating an NC part program for laser machining in which a figure definition statement for defining a figure and a motion definition statement for defining a laser beam path are inputted in an automatic programming language, and these definition statements are converted, by using an NC data output table, into a laser machining NC part program executable by an NC unit, which NC part program is then outputted, said method characterized by: creating a machining condition modification definition statement which includes data specifying a machining condition modification interval at a corner portion of a part and machining conditions in said interval; creating a figure definition statement and a motion definition statement without taking the machining condition modification interval and machining conditions into consideration; dividing the corner portion into two or more machining condition modification intervals using said machining condition modification definition statement when a laser machining NC part program executable by the NC unit is created using the definition statements; and creating the laser machining NC part program in such a manner that machining conditions set by the machining condition modification definition statement will prevail in each of the intervals.
