Ultra short-pulsed laser ablation modelling
Use and programming of software for execution virtual parameter studies in laser ablation. The goal is to make use of modeling techniques in order to reduce the number of experiments. This should lead to a faster and better results in laser ablation process development.
Laser ablation with ultra short-pulsed laser is an emerging manufacturing technique. The interaction time between the laser and the material is shorter than the electron relaxation time, which enables material removal without a melt phase and very low heat impact. The result is a workpiece without heat affected zone. Therefore, laser ablation is applied in various industrial diciplines such as watch manufacturing, medical implants, turbine blades or tool manufacturing. However, the evaluation of the processing parameters for manufacturing of new geometry is done with a high degree of experimental testing. Simulation methods for calculating the material removal are highly demanded. Our institute is already working with a software to perform virtual experiments to manufacture a part with ultra short-pulsed laser processing. Thanks to the software, we are able to predict material removal of ultra short-pulsed laser processing for new geometries without needing a laser setup. The next step is to train this this software for new materials and application to more complex processing conditions, such as tilt angle variation.

Within this thesis, the prediction of material removal for ultra short-pulsed laser ablation should be improved by training the ablation model applied in a software for process design. The goal is the selection and evaluation of process parameters and a processing strategy for a laser ablation process.
