Abstract
High speed cutting (HSC) has received growing attention in recent years due to its widespread applications in modern manufacturing. However, the theoretical understanding of the HSC process is considerably underdeveloped in comparison to the rapid progress of its practical application. To improve the state of knowledge of this topic, the German Research Association (DFG) has funded some research projects. One of them is the improvement of finite element simulation techniques of the HSC process. It covers the chip formation description, development of material laws for the description of HSC-conditions, the prediction of lamellar chips, the calculation of residual stresses, resulting temperature fields in the cutting tool and first descriptions of spatial chip formation. The paper will give an overview of the current progress in this project.
