PURPOSE:To provide a laser beam machie and a laser machining method capable of removing a troublesome adjusting operation requiring labor with a comparatively inexpensive optical part. CONSTITUTION:A laser beam oscillator 1, an expander 3. a liquid crystal mask 4, a condenser lens 11, a liquid crystal mask driver 14, a mask pattern data compensator 15, a mask pattern data storage device 16 are provided, when a pattern marked on a printing object 12 is deformed by a strain, etc., to a pattern displayed on a liquid crystal mask 4, a mask pattern data is compensated by a compensator 15 and the pattern displayed on the liquid crystal mask 4 is deformed purposely, deformations such as a strain are compensated to mark good patterns on the printing object 12. |
