The Finite Element Method (FEM) is used to investigate size effects in micro-cutting of steels. For this a material routine based on a plasticity model for high speed deformation was implemented in the FEM-package ABAQUS. A dimensional analysis ot the material model used was performed and in combination with FEM-simulations similarity relations for the simpler model problem of single shot impact were derived. It was started to transfer this strategy to microcutting. For later verifiatons experimental cutting studies were performed in which cutting forces and roughness of Steel St37 were measured in a dry turning process using tools with different cutting edge radii and a high precision Kugler MicroMaster 2.
