MEASUREMENT LIGHT IRRADIATION APPARATUS OF TEACHING USE FOR LASER PROCESSING

摘要

PROBLEM TO BE SOLVED: To provide a measurement light irradiation apparatus of teaching use for laser processing which is capable of safely avoiding a damage of a function of a measurement light irradiation head.SOLUTION: A measurement light irradiation apparatus S of teaching use for laser processing is equipped with a laser processing head 10 and comprises a measurement light irradiation head 100 which irradiates a surface of a workpiece W with auxiliary measurement light Lm for teaching an area Wc to be processed. A shutter mechanism 120 which opens a front surface of a measurement light irradiation port 100a when the measurement light irradiation head 100 is used and shields the front surface of the measurement light irradiation port 100a when the measurement light irradiation head 100 is not used is provided for a front side of the measurement light irradiation port 100a of the measurement light irradiation head 100.
