摘要： PURPOSE:To prevent the distortion of a work by irradiation with a laser beam by providing rollers which pinch the work on both surfaces of the work. CONSTITUTION:The work 4 is pinched by the lower roll 6 and the upper roll 7. While the work 4 is driven in a direction Y by an NC unit, the work is irradiated with the laser beam from a machining head 1 and is subjected to prescribed machining. The work 4 is held restrained by the upper and lower rollers 6, 7 even if warping force acts near the part irradiated with the laser beam in either upper or lower direction. The work does not, therefore, bend.

摘要： PURPOSE:To provide a laser beam machine which can obtain the quality of a stable working surface even when the state of the surface of a work to be an irradiated part with laser beam changes or the reflectance of a reflecting mirror changes. CONSTITUTION:The laser beam 2 outputted from a laser beam oscillator 1 is transmitted by the reflecting mirror 3 to a condenserlens 4, the laser beam is condensed by this condenserlens 4 and irradiates the work 6 fixed on a working table 5. The surface temperature of the irradiated part of the laser beam on the surface of the work 6 is detected by a temperature measuring device 9 to output measured data. A temperature controller compares a heating pattern (temperature pattern) inputted in advance with the measured data to control the output of the laser beam oscillator 1 by a laser beam controller 7 so that the temperature difference is made small. Then, the temperature of the irradiated part with the laser beam on the surface of the work is held on a definite temperature pattern.

摘要： PURPOSE:To prevent the deterioration of machining quality by detecting a lowering of reflectance of a reflection mirror and inputting a correction value obtained from the reflectance, a discharge current and initial laser beam output to a laser beam power source via a current control circuit. CONSTITUTION:A laser beam 2 is emitted from a laser beam generator (resonator) 6 where a set value of an output setter 7 is compared with a detection value of the discharge current to control the discharge current to a specified value. The laser beam 2 is led to a condenser lens 4 via the reflection mirror (beam splitter) 13 and a work 5 is irradiated and machined therewith. The lowering of reflectance of the reflection mirror 13 is then detected by a photodetector 11. The correction value of the discharge current obtained from the reflectance of the reflection mirror 13 and characteristics of the discharge current and the initial laser beam output inputted in advance is inputted to the laser beam power source 8 by an arithmetic correction circuit 12 via the current control circuit 9. By this method, a lowering of the intensity of the laser beam with which the work is irradiated can be prevented.

The housing part 6 for a television camera 13, a change-over mirror 8 and the correction lens 14 is mounted between the total reflecting mirror 3 and the condenser lens 4 by freely vertically expandable and contractable transmission pipes 24A, 24B and the visible light 10 from a light source 9 is projected to the work 5a via a semi-permeable mirror 11, the correction lens 14 and the change-over mirror 8. The position to be irradiated with laser light is then observed. The housing part 6 is properly driven in a vertical direction by a pulse motor 22 to position the housing part 6 to attain the specified image formation position without changing the lens 14 when the focal distance of the lens 4 varies in this constitution.
