The current state of the art shows that the friction behavior during machining is not yet fully understood, requiring further research. A novel method for analyzing friction mechanisms in machining was proposed in this study, revealing a significant influence of the sliding velocity of the chip on the coefficient of friction across a wide range of coating properties and cutting velocities.
The current state of the art shows that the friction behavior during machining is not yet sufficiently understood and that there is still a need for further research. This represents a major obstacle to the successful further development of friction models for chip formation simulations. Therefore, a novel method for the analysis of friction mechanisms in machining via high-speed chip formation recordings is presented in this study. Within the frame of the investigations, a significant influence of the sliding velocity of the chip on the coefficient of friction could be determined over a wide range of different coating properties and cutting velocities.
