The main objective of this research work is to investigate size effects by down scaling the twist drilling process into the micro range (drill diameter: d = 50 μm -1 mm). Therefore, experimental micro drilling tests in ferritic-pearlitic carbon steel C45 are performed with different cutting parameters and compared with data obtained from conventional drilling. Based on the concept of a representative volume element (RVE) and constitutive material modelling, as well as using the Lagrangian
