FIELD: machine building.
SUBSTANCE: coordinate marks are applied on specimen surface by pressing the tool there against, tool hardness exceeding that of the part material. Said tool represents an etching with sharp protruding elements shaped to tetrahedral pyramid that make a preset system of coordinate (reference) points. The latter are the points of intersection of analysed specimen with faces on indenter. Produced recesses are filled with non-solidifying luminescent dye not losing its properties at plastic strain. Now, said specimen is subjected to machining. Then, parameters of grating changed pattern are measured to calculate the plastic strain parameters.
EFFECT: higher pattern quality and accuracy of metal plastic strain parameter measurement.
