Taladrado láser mediante un láser convencional

Abstract

Nowadays, laser drilling is increasing its

relevance among the industrial applications,

especially in the aeronautical sector for the

manufacture of small holes in the blades of a

turbine for their internal cooling. There are more

applications in other sectors like automotive

or energy, where high aspect ratio drills are

demanded. Currently there are robust industrial

solutions to perform these type of drills, but

these system are specific for this application

and present high costs. On the other hand,

conventional solid state lasers are relatively

widespread in the industry for laser cutting

or welding. Thus, the present article presents

a double objective: On the one hand, a laser

percussion drilling process for high aspect

ratio holes using a conventional laser will be

evaluated. On the other hand, in the article is

shown the development of a numerical model or

estimating the internal geometry of the hole and

the temperature field of the workpiece for the

different operating conditions.
