DEVICE FOR PROCESSING WORKPIECE BY CUTTING WITH LASER BEAM Russian patent published in 2022 - IPC B23K26/03 B23K26/146 

FIELD: laser systems.

SUBSTANCE: invention relates to device (100, 200, 300, 7000) and method (400) for processing workpiece (101) by cutting with laser beam (102). Device (100, 200, 300, 700) contains processing unit (103) made with the possibility of supplying jet (104) of fluid under pressure to workpiece (101) and injecting laser beam (102) through at least one optical element (105) into fluid jet (104) in the direction of workpiece (101). Measuring unit (107) of the device is made with the possibility of receiving laser-induced electromagnetic radiation (106) distributing from workpiece (101) through fluid jet (104) and through at least one optical element, and with the possibility of converting received radiation (106) into signal (108). Device (100, 200, 300, 700) contains signal processing unit (109) made with the possibility of determining the processing state of workpiece (101) based on signal (108), aimed at improving traditional devices and solutions.

EFFECT: increase in the accuracy of determining the state of the workpiece processing, i.e., whether the laser beam has passed through workpiece material, which makes it possible to better optimize the processing in time and improve the quality of processing.
