The durability of cutting inserts and also the quality of produced components depend decisively on the geometry and surface of the cutting edge. Conventional processes for tool preparation, like grinding or micro blasting do not provide an exact and consistent rounding of the cutting edge. Therefore, a new laser based technology for finishing of cutting tools regarding the preparation has been investigated. Defined edge geometry in combination with high surface quality have been achieved. With short uv- and green-laser pulses in the range of ns or ps emitted by diode-pumped solid-state lasers (DPSSL), the thermal impact on the machined area and surrounding material can be minimized. First chip removing tests show the potential and flexibility of this preparation technology in comparison to conventionally rounded cutting edges. For basic investigations, a four-axes positioning system has been used and in order to machine nearly any geometry of cutting tools without limitation regarding the angle of irradiation, a six-axes precision positioning system has been set up. The design of the six-axes system allows a high degree of freedom for machining without re-clamping the target. An integrated measurement system with digital image processing is used for 3-d tool path generation. Additionally, the detection of jagged edges on the pre-machined cutting tool is implemented into the digital image processing. This will be used for the selective adaptation of the process parameters.
