his paper presents a study on the modelling and investiga-tion of the surface generation process during Atomic Force Microscopy (AFM) probe-based mechanical machining of dual-phase materials. The proposed model considers the ef-fects of the cutting tip geometry, the step-over between linear machined grooves and the minimum chip thickness as well as the elastic recovery of different phases present within the workpiece microstructure. In particular, the model takes into account changes in the machining response between phases, i.e. transitions from cutting to ploughing and vice versa, and the influence of such variations on the machined surface. These alterations in the machining response are mainly at-tributed to the dissimilarity in the values of the minimum chip thickness and the elastic recovery of the different processed phases. Therefore, investigations were initially conducted to examine the phases to be machined and thus to identify some of their mechanical properties.
