Abstract

PURPOSE:To easily detect the machining condition of a workpiece, by continuously detecting each light energy which is produced by the temperature rise of the workpiece due to laser. CONSTITUTION:When the temperature of the workpiece 6 is raised by the laser 2, the light energy proportional to the temperature is produced. The light energy is converted into a voltage by a light quantity converter of a light quantity detector 7. The voltage is compared with previously set upper and lower limit voltages by a calculator 8 connected to the light quantity detector 7. The result of the comparison is picked out from an output unit 20 connected to the calculator 8. It is displayed by indicator lamps 12, 14, 16 of the output unit 20 whether or not the voltage corresponding to the temperature of the workpiece 6 is within a predetermined range. The right and wrong of the machining can be easily discriminated if the upper and the lower limit voltages are appropriately set in the calculator 8.
