Experimental validation of ball burnishing numerical simulation on ball-end milled martensitic stainless-steel considering friction and the initial surface topography

Numerous simplified numerical models have been established to optimize the ball burnishing of steel surfaces. Nevertheless, their conceptualization has not considered tool – part interaction, leading an unsatisfactory process parameterization. As a solution, structured simulation defined that reproduces this interaction by several friction coefficient approximations. This study provides tribological inputs (friction and initial surface conditions) model, adapting it pre-textured martensitic precipitation hardening stainless-steel. Results show versatility model reproduce integrity alterations. Hence, consistent configuration can be postulated as economical efficient approach tackle parameterization according applicability manufactured parts.
