Abstract

A laser beam machine easily prepares a data bank of machining conditions and also easily creates a machining program from the machining conditions. When a suitable trial machining condition D1 is derived, the trial machining condition D1 is stored in a memory area as the machining condition for a machining step concerned. The machining condition is stored in accordance with a signal entered by an operator to create a machining condition data bank. In addition, an output state data D2 of a laser oscillator obtained during laser beam machining according to the trial machining condition D1 is stored. A registration code is assigned to the machining condition and the stored output state data. A machining condition corresponding to a machining path specified in a generalized machining program P.sub.0 is extracted from the machining condition data bank and the extracted machining condition is set in the generalized machining program to create a specific machining program P.
