Abstract
Despite crucial efforts invested into computational methods, explicit dynamics simulation of cutting operations may still be unacceptably expensive. Therefore, in many cases a two-dimensional model is considered. Here an overview of the possibilities of two-dimensional simulations is given. For this, simulation and measurement of a straight turning process on AISI 1045 steel is presented. In the numerical analysis, material behavior and its failure was described by Johnson-Cook law, considering damage evolution. Coupled thermo-mechanical model with mass-scaling and adaptive remeshing was built. The numerically obtained cutting force was compared to the measured data. It was found that the forces obtained with simulation and the measured ones show good agreement. Sensitivity analyses were performed to examine the influence of specific parameters on the reaction force. The effect of these parameters is also shown.

Summary
Cutting is one of the most important material removal process. In case of mass production even small enhancement of a machining process can cause significant cost reduction and quality improvement for the product. Deeper understanding of the relation between machining parameters (cutting speed, feed rate, depth of cut, etc.) and output variables (cutting forces, temperature field, surface roughness, chip morphology, etc.) could be a key to such improvement. In the last few decades, substantial research effort has been invested into the development of computational methods and their implementations. The identification of physical variables in simulations of machining processes could be performed efficiently. Despite the efforts to reduce the cost of computational speed, explicit dynamics simulation of cutting operations may still be unacceptably expensive. The usage of 2D model could be considered
