METHOD AND DEVICE FOR DRILLING COMPONENTS
Abstract
The invention relates to a method for drilling components made of metal materials and components made of coated metal and dielectric materials. The spatial distribution of the Poynting vector assigned to the laser radiation is set differently in an overlap region of the bore to be produced, which is assigned a bore axis, a bore wall, and a bore base that is advanced as the bore depth is advanced, than in an edge region of the bore to be produced, wherein the overlap region is defined as the region which is irradiated using laser radiation with a high energy flux density during a single-pulse drilling process, and the edge region is defined as the region which lies outside of the overlap region and which is irradiated using laser radiation with a low energy flux density, lower than the energy flux density used in the overlap region, during the drilling process. The invention also relates to a corresponding device.
