AUTOMATIC PROGRAMMING DEVICE AND AUTOMATIC PROGRAMMING METHOD FOR LASER PROCESSING MACHINE, AND LASER PROCESSING SYSTEM

摘要

An automatic programming device (9) generates an operation program for controlling the operation of a laser processing machine using square pipe shape data and product shape data stored in a storage means. When a processing program is created for a case in which a product is obtained by cutting each face of the square pipe and cutting in a direction that is inclined at a prescribed angle with respect to the axial direction of the pipe, the programming device lays out a processing trajectory where a cutting process is performed on a developed diagram wherein the square pipe is laid out on a given straight line parallel to the axial direction of the square pipe. The programming device is equipped with a processing trajectory changing means which, when the processing trajectory in the direction perpendicular to the axial direction of the member being processed protrudes toward the product-shape side in the developed diagram wherein the processing trajectory has been laid out, changes this protruding processing trajectory so as to shorten the trajectory by a prescribed length.
