The tribological conditions for mating surfaces can be improved by surface structuring. For tool rake faces, this can lead to reduced frictional forces. This work suggests a new approach and contributes to the assessment of geometric parameters and location of rake face surface structures. A femto-second laser was used to machine structures to a Taguchi experimental design inspired by contact length modelling. Cutting tests were done to assess feature dimensions/location from the cutting edge. This paper makes a significant contribution to the fundamental design principles for location of rake face structures and their impact on contact phenomena.
