METHOD FOR RAPID DIAGNOSIS OF METAL PROCESSING MACHINE MODULES Russian patent published in 2020 - IPC B23Q17/00 G01M13/00 

FIELD: methods and devices for metal processing.

SUBSTANCE: invention relates to machine building and can be used in determining presence and location of defect in modules of metal working machines in real time mode. Method comprises determining a geometrical image of a surface of a workpiece in form of a frequency spectrum, reflecting changes in the tool and workpiece vibrations along the normal to the processed surface, comparison of the current geometric image with the reference image, according to the results of which the presence and location of defects in the machine modules is determined. Reference geometric image is realized in the form of recurrent neural networks with long short-term memory, and determination of the presence and location of defects in said modules by deviation of the current geometrical image from the reference is carried out using an intelligent classifier, which is presented in the form of a multilayer perceptron.

EFFECT: use of the invention enables rapid and reliable diagnosis of the state of machine modules.
