.Result
A reduced ablation model, which describes the pulse-resolved
evolution of the drill hole, has been developed, numerically
implemented and confirmed by comparison with experimental
data (Figure 3). Fraunhofer ILT will offer an interactive simulation
software (»DynamicDrill«) for use on a PC, laptop or smart
devices in the spring of 2016.
Applications
In addition to the application described here, drilling metals
with long pulsed laser radiation, the developed ablation model
can also be applied in the field of USP ablation of dielectric
and semiconducting materials.

Task
The asymptotic ablation contour observed when long pulsed
laser radiation is used to drill can be excellently described by
»AsymptoticDrill«, a software developed at Fraunhofer ILT.
However, this software only describes the final contour while
assuming constant pulses. A variation of the pulse characteris-
tics during the process can have a significant influence on the
drilling and, thus, lead to a significant improvement in quality
(for example, cylindrical drill holes). This state creates the need
to develop a dynamic ablation model, one which can describe
the pulse-resolved evolution of the drill hole.
Method
The aim of modeling and simulation is to describe and predict
the pulse-resolved evolution of the drill hole on the basis
of a reduced ablation model. According to the asymptotic
ablation model, this new model should allow the customer
to implement interactive simulation software for direct use.
