Abstract The mechanical parameters of quenched and tempered AISI4140 the machining process characteristics are depending on material’s tempering state. practical relevance not only cutting forces tool wear, but also surface layer states machined part. In order to predict improve these efficiently, chip forming simulation via finite element method (FEM) is commonly applied. However, an issue in ...

Abstract To study the manufacturability and mechanical properties of a low alloy heat treatable medium carbon steel by additive manufacturing, 42CrMo4 (AISI4140) specimens were manufactured laser powder bed fusion. Influences processing parameters on relative density crack investigated. Moreover, Charpy impact tests, microhardness, tensile tests for with without preheating also studied. Results...

Abstract The contact length is one of the most important factors to evaluate chip formation process and mechanical loads in metal cutting. Over years, several methods identify were developed. However, especially for wet cutting processes determination still challenging. In this paper, three dry Ti6Al4V AISI4140 + QT are presented, discussed analyzed. first approach uses tools with a microtextur...
