Abstract
This contribution presents a physical cutting process model based on the Discrete Element Method (DEM), which allows the simulation of dynamic and thermal interactions in metal cutting. Core component of the approach is the DEM model of a solid with elastic-plastic deformation modes, which is verified in standardized tensile and Charpy impact tests as well as other non-standardized tests. The model is enhanced such that the thermo-dynamics of a solid due to heat conduction can be included, which is also verified in different tests. The applicability to model-cutting processes is shown in the simulation of orthogonal cutting processes. The results of the simulation are compared to experimentally obtained results for both forces as well as temperatures. For verification purposes, an FEM model is made, which predicts both forces on the tool as well as temperatures
