PURPOSE:To reduce the generation of defects by checking a machining state after machining, correcting a difference between an inputted standard pattern and re-machining in a laser beam machining. CONSTITUTION:A pattern recognition device 1 recognizes a pattern of a work 2, calculates a machining position from a standard position on the pattern of the work, moves the work or an irradiation device 3 so as to match the machining position and the irradiating position and executes laser beam machining. After machining, the pattern recognition device recognizes the pattern of the machining position, compares it with a standard laser beam machining pattern preliminarily inputted in a controller 5, and when the pattern lies within the range of standard, the machining of the position is completed, and reversely, when the machining pattern is out of the standard pattern with comparing them, re-machining is executed, a miss machining is eliminated and the yield of products is improved. |
