Cutting fluids significantly influence the contact conditions in metal cutting, e.g. stresses or contact areas. Due to the limited accessibility of the chip-tool contact, the identification of contact conditions is challenging. In this paper, a simulation model is created and used to identify the real contact area in dry and wet cutting. Experimentally identified normal stresses and chip-tool roughness serve as input parameters. The results show higher normal stresses in wet cutting, which results in a higher real contact area between rake face and chip.
