<p><P>PROBLEM TO BE SOLVED: To provide technique by which a temperature range which is the standard of deciding whether the quality of working is good or bad can be calculated about every object of working. <P>SOLUTION: The method of laser beam working is provided with: a process where a laser beam for reference is emitted on a surface of the object 38 of working; a process where the intensity of the beam which is reflected by the surface is detected with the reflected intensity sensor; a process where the transmissivity or the rate of absorption of the object 38 of working is calculated on the basis of the output; a process where allowable temperature range to be the standard for deciding the quality of working is calculated on the basis of this transmissivity or the like; a process where a laser beam for working is emitted onto the surface of the object 38 of working; a process where an infrared ray having a prescribed wavelength which is radiated from the object 38 of working is detected with a first infrared sensor; a process where an infrared ray having a different wavelength from the above wavelength which is radiated from the object 38 of working is detected with a second infrared sensor; a process where the temperature of the object of working is calculated on the basis of the output from both infrared sensors; and a process where the output of the laser beam for working is adjusted when the temperature of the object 38 of working is deviated from the allowable temperature range. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
