The paper considers the transfer of process heat to the three main-components involved in the cutting process (chips, cutting tool and work piece). To predict thermal caused deformations and there from deduced errors FEM simulation models are used. The simulation makes it possible to identify relevant parameters and determine their influence on the manufacturing accuracy. The results of the simulation are verified again by practical tests for an exact determination of the thermal boundary conditions. From these findings approaches to a solution for compensation and error minimisation are derived.
