Abstract:
A method of laser processing in which holes are formed in an article provided in the form of a sheet, the method comprising:clamping the sheet between clamps separated a distance from one another;applying tension to said article to be processed by applying bias to said clamps in a direction such as would relatively separate said clamps; anddirecting a laser beam onto a portion of said article extending between the clamps while maintaining said bias, further comprising:preliminarily calculating an amount of displacement of laser processing points caused when the article that has been stretched by the applied tension is released from the tension and resiled:correcting data for controlling the laser processing points according to calculation results obtained from said step of preliminarily calculating; andperforming the laser processing based on the corrected data obtained from said step of correcting.
