Dry Cutting Experiments Database Ti6Al4V and Ck45
Hagen Klippel, Stefan Süssmaier, Michal Kuffa +1
The numerical simulation of metal cutting processes requires material data for constitutive equations, which cannot be obtained with standard material testing procedures. Instead,…
Johnson Cook Flow Stress Parameter for Free Cutting Steel 50SiB8
Hagen Klippel, Marcel Gerstgrasser, Darko Smolenicki +3
The present documents deals with the material characterization of the free cutting steel 50SiB8 for numerical simulations. Quasi-static tensile tests as well as Split Hopkinson Ten…
Self-Optimizing Grinding Machines using Gaussian Process Models and Constrained Bayesian Optimization
Markus Maier, Alisa Rupenyan, Christian Bobst +1
In this study, self-optimization of a grinding machine is demonstrated with respect to production costs, while fulfilling quality and safety constraints. The quality requirements o…
Model order reduction of thermo-mechanical models with parametric convective boundary conditions: focus on machine tool
Pablo Hernández-Becerro, Daniel Spescha, Konrad Wegener
This paper presents a parametric Model Order Reduction (MOR) method for weakly coupled thermo-mechanical Finite Element (FE) models of machine tools and other similar mechatronic s…
Meshless Methods for Large Deformation Elastodynamics
Matthias Röthlin, Hagen Klippel, Konrad Wegener
Meshless methods are a promising candidate to reliably simulate materials undergoing large deformations. Unlike mesh based methods like the FEM, meshless methods are not limited in…
Flash Temperature and Force Measurements in Single Diamond Scratch Tests
Mansur Akbari, Mikhail Kliuev, Jens Boos +1
Analysis of the highest temperature in the machining processes, namely the flash temperature, helps to understand the physics of the process, to improve cutting tool geometry, and…
