Simulation of the status of the surface layer of a tool with a wear-resistant ion-plasma coating in the processes of OMD
In this study, the influence of a wear-resistant coating applied to the working edge of a stamping tool on the stress-strain state in the deformation zone was determined. In the Ansys LS-dyna software package, mod-els of punching processes with a tool with a wear-resistant coating and without a coating were built, visual interpretations of the distribution of stress fields in the tool material were obtained, graphs of stresses and potential energy in the elements of the surface layer at critical points of contact at characteristic stages of the punching process were obtained. sheet material.
