Metrological and structural-mechanical aspects of technology for recovery by surfacing of open dies made of 5KhNM steel

The technology for recovery by surfacing of open dies made of 5KhNM steel is improved. In order to improve the quality and productivity of repairs, a metrological assessment of its geometry using the coordinate measurement method and the Hexagon manipulator is introduced to assess the type of wear of the engraving and die elements. Based on the identified type of wear of the die engraving and the determination of the necessary mechanical treatment for surfacing, the selection of its chemical composition, the determination of the volume and modes of surfacing to obtain the required structural and mechanical properties of the fused layers of material are performed.
