Abstract
Cutting tool performance and life span is decisively determined by tool micro geometry. Honed cutting edges as well as special tool micro shapes are mainly produced by abrasive processes. Recently there is a growing interest in alternative processes such as laser beam material removal in order to achieve a higher diversity and flexibility in tool micro shaping. The parameters applied in laser machining are responsible for the material behavior during machining and for the material properties after machining. The presented paper shows the effects of laser beam material removal on the properties of carbide cutting tools. As most of these tools are coated before use, the influence of subsequent PVD-coating process steps on carbide characteristics is also investigated. The results are compared to those of not laser machined tools. An influence of laser machining on roughness, phase composition and residual stress could be demonstrated, depending on laser machining parameters.
