Contactless surface flattening of additive manufactured nickel-base alloy parts by ultra-short pulsed laser ablation
(2020)Procedia CIRP ~ 20th CIRP Conference on Electro Physical and Chemical MachiningNickel-base alloy samples produced by selective laser melting (SLM) exhibit high surface roughness of 14.2 μm ±4.8 μm standard deviation at the sidewalls. Ultra-short pulsed (USP) laser ablation at a pulse duration of 10 ps is applied to reduce the surface roughness. This flattening method does not require a melting phase. The influence of the tilt angle and the orientation of the SLM layers on the surface topography of the sample is ...Conference Paper -

Parameter Identification of a Friction Model in Metal Cutting Simulations with GPU-Accelerated Meshfree Methods
(2021)WCCM-ECCOMAS Congress ~ WCCM-ECCOMAS2020A modular computational framework is presented for the identification of friction parameters in metal machining applications. Numerical simulation of such processes using mesh-based techniques (usually) necessitates the cumbersome re-meshing procedures and is hard to parallelize. Therefore, the present framework synthesizes the advantages of mesh-free methods with GPU parallel computing, offering an efficient tool for the optimization ...Conference Paper -
