LASER MACHINING APPARATUS

To suppress load on a control system and furthermore to widen an imaging field of view of an imaging unit.SOLUTION: A laser machining apparatus L comprises: a transmissive window 19 that emits a laser beam toward the outside of a housing 10; a transparent member 19b that transmits the laser beam emitted from the transmissive window 19; and a wide-area camera 6 that generates a workpiece image Pw including at least a part of a machining region R1 by imaging a workpiece through the transmissive window 19. The transparent member 19b is made of a flat member generating substantially no lens effect. The wide-area camera 6 is arranged in the housing 10 in an attitude in which an imaging optical axis Ac and the machining reference face Rb, which is a reference for position information, are orthogonal to each other.SELECTED DRAWING: Figure 10 【課題】制御系の負荷を抑制しつつ、撮像部の撮像視野を広げる。【解決手段】レーザ加工装置Ｌは、レーザ光を筐体１０の外部に出射する透過ウインドウ１９と、透過ウインドウ１９から出射されるレーザ光が透過する透明部材１９ｂと、透過ウインドウ１９を通じてワークＷを撮像することにより、加工領域Ｒ１の少なくとも一部を含んだワーク画像Ｐｗを生成する広域カメラ６と、を備える。透明部材１９ｂは、レンズ効果が略非発生の扁平な部材からなり、広域カメラ６は、その撮像光軸Ａｃと、位置情報の基準となる加工基準面Ｒｂと、を直交させた姿勢で筐体１０内に配置されている。【選択図】図１０
