Investigation of surface hardening effect on the local mechanical properties of the cutting tools working edge
Investigation of surface hardening effect on the local mechanical properties of the cutting tools working edge
DOI: 10.22184/1993-8578.2020.13.7-8.434.441
In this work the mechanical properties of the punching die cutting edge were investigated by instrumental indentation. The near-surface layer of punching dies is modified in the process of mechanical action with a milling tool and local heating by a laser. Profiles of the hardness on depth have been constructed using the method of automated mapping. It was found that the processing of the tip by local laser heating leads to an increase in the hardness of the alloy by a factor of 1.5 in the region of about 40 μm.
