Simulation of the Chip Formation

The article deals with the simulation of chip formation at different ratios between the rounded cutting edge and cutting thickness. Aim of the research has been focused on the interpretation of new knowledge from the cutting theory. Authors have tried to understand the theory of cutting process by means of simulation and provide the recommendations for practical usage. They explain the differences between the Merchant's model with a sharp edge and a model with a rounded cutting edge. The contribution also describes the changes and manifestations of physical phenomena result from it. Achieved results enable not only better integration of cutting tools into the manufacturing, but they also allow increase in the machining efficiency.
