N2 - During the turning process of metastable austenitic steels, austenite is transformed into hard martensite by plastic deformation at low temperatures. This enables the production of components, which have both a hardened subsurface zone and a ductile core. Cryogenic cooling allows the subsurface zone to be hardened during machining, which leads to a shortening of the process chain. However, effects such as wear can make it challenging to adjust the properties of the subsurface zone during turning. By adjusting the tool microgeometry with a flank face modification, the wear condition can be kept constant for a certain period. In addition, the significance analysis with different tool microgeometries shows that only feed and initial temperature have a significant effect on the martensite formation.
