LASER BEAM MACHINING APPARATUS, OFFSET ADJUSTING METHOD IN HEIGHT DIRECTION IN THREE-DIMENSIONAL LASER BEAM MACHINING, AND CONTROL PROGRAM OF LASER BEAM MACHINING APPARATUS |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining apparatus capable of suppressing dispersion of the machining accuracy and the machining quality between works when machining characters or the like on the works having different heights. <P>SOLUTION: The laser beam machining apparatus comprises a machining pattern storage unit 116 for storing machining pattern information, an offset designation generation unit 115 for generating the offset designation for designating the offset quantity with respect to a reference machining surface of a machining surface based on a detection signal from a worksensor 101 detecting the work, a machining pattern changing unit 117 for changing position information in machining pattern information based on the offset designation, a scanning control unit 120 for scanning laser beams L based on machining pattern information after changing position information, and a beam diameter adjustment unit 119 for controlling the focal distance of the laser beams L based on machining pattern information after changing position information. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
