Due to friction, plastic deformation and cutting, the drilling process leads to high mechanical and thermal loadings of drilling tool and workpiece. Distortion and modifications of the surface layer microstructure, especially rehardened zones, can be observed, whereby the experimental investigation of correlations between machining processes and resulting surface layers are very complicated and time...
Depending on machining process, machined material, cutting and tool parameters as well as the resulting heating and cooling rates the heat in cutting processes can lead to phase transformations in the work piece surface layer. This paper presents an approach to predict and analyze cutting induced phase transformations in surface layers. Therefore a 2D-FE-cutting simulation model has been developed...
