Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The goal of this thesis was to develop a model for structural surface modifications in metal cutting. Cutting tests on steel AISI 4140 (42CrMo4) showed that dynamic recrystallization (DRX) formed nano-crystalline surface layers. The kinetics of DRX were analytically modeled by the thermodynamic Helmholtz potential, considering the internal energy as well as the production and flow of entropy. Finally, DRX was predicted in finite element simulations and process signature components were compiled. 156 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This thesis presents the development and validation of a predictive methodology of tool and process design for stable chip breakage in metal cutting. The physics of chip breakage were modeled by a new ductile fracture criterion, which was implemented into a numerical turning simulation model. Additionally, three new models quantify the sensitivities of ductile fracture in the breakage location with respect to the tool and process parameters. A case study showed the high industrial potential of the developed methodology. 188 pp. Englisch.…
