In the LaBoKomp joint project, the LZH scientists tested the laser drilling process and the system on so-called “cargo struts”. These are C-shaped struts as they are used to stabilize the cargo hold floor. With a drilling time of less than 10 seconds per hole, the new method is now on a par with conventional ones - without the disadvantage of tool wear or the risk of delamination.
Continuously adjust parameters in the process
The basis for the automated process is the specially developed software. It enables drilling strategies in which parameters can be continuously adjusted during the process. This enables the drill holes to be of optimal quality that also meets aviation standards.
Project partner Invent was able to demonstrate that the laser holes are equivalent to conventional holes. Whole work orders can be programmed by specifying a few manipulated variables. The process is continuously monitored by thermography and the heat dissipation is regulated based on this.
Change modules flexibly
The system was planned and designed together with the KMS Technology Center GmbH and then put into operation at the LZH. The system includes a new type of laser from the associated partner Trumpf. The modules developed by KMS can be changed flexibly and adapted to different applications.
Seminar tip
The seminar on lightweight materials in construction teaches methods, design principles and construction methods for lightweight structures. The participants get an overview of different lightweight materials, learn about criteria for the selection of materials and learn about the advantages, disadvantages and risks of the different materials.
Drilling multiple laminates possible
The system and the process are suitable for all CFRP types commonly used in aviation , as well as laminates with GRP top layers and Coppermesh. It is also easy to drill different laminates placed one above the other.
