Abstract
Basic knowledge of mechanical stresses is essential for an adapted tool design. A method for calculating internal stresses based on measured external stresses is shown. This eliminates the need for modelling the tool, chip and workpiece interaction as it is required in FE-based chip formation simulations. Thus, in-situ elastoplastic effects, such as springback or built-up edges, are directly considered. Using this approach, internal stresses of worn cutting tools are calculated at different wear states in order to understand tool wear. The experimental investigations show that for the machining of AISI1045+N principal stresses σ1 are the significant cause for tool failure.
