Drilling holes in the key parts of automotive transmissions (e.g. the crank shaft) can be difficult and time consuming. For this reason, laser assisted drilling is proposed to increase processing speed and reduce wear of tools. In this paper, an experimental study is used to investigate optimum processing parameters of laser assisted drilling in different materials relevant for the automotive industry, such as 45 steel , 40Cr steel , QT600 steel and stainless steel 430L. The experimental results show that laser assisted drilling offers process improvements and are provided with a high application value.
