dc.description.abstractEnProcessing of helicopter engines faster, better and more reliably is the triptych which binds LOMA, ALPhANOV and TURBOMECA. In current production machines, flash lamp pumped lasers are employed to drill thousands of cooling holes with specific geometries and diameters to ensure a homogeneous air flow over the surface. However we aim to enhance the production process. Therefore, the three partners started an initiative to identify and overcome the shortcomings of the current process, where the laser source is a key element for improvement.<p> </p> In this paper, we report on the latest developments in multi-pulse drilling using an IPG fiber laser. The latter delivers, at a tunable repetition rate (from single shot up to 2 kHz), laser pulses whose width and peak power are adjustable in between 0.2 - 10 ms and 0 - 12 kW respectively. We have focused our work on drilling of thick sheets of metal alloys with different geometries and different processing strategies. We will show that using such laser system it is possible to decrease the processing time while limiting the heat affected zones and collateral effects. Finally, the impact of the different physical processes in play during the drilling on the geometry of the holes will be discussed.
