dc.description.abstract
In the last years, laser beam drilling became increasingly
important for many technical applications as it
allows the contactless production of high quality drill holes.
So far, mainly short laser pulses are of industrial relevance,
as they offer a good compromise between precision and efficiency
and combine high ablation efficiency with low thermal
damage of the workpiece. Laser beam drilling in this
pulse length range is still a highly thermal process. There are
two ablation mechanisms: evaporation and melt expulsion.
In order to achieve high quality processing results, a basic
process understanding is absolutely necessary. Yet, process
observations in laser beam drilling suffer from both the short
time scales and the restricted accessibility of the interaction
zone. Numerical simulations offer the possibility to acquire
additional knowledge of the process as they allow a direct
look into the drill hole during the ablation process. In this
contribution, a numerical finite volume multi-phase simulation
model for laser beam drilling with short laser pulses
shall be presented. The model is applied for a basic study of
the ablation process with μs and ns laser pulses. The obtained
results show good qualitative correspondence with
experimental data.
