Abstract:
The influence of friction on machining processes, considering pressure, velocity, and temperature, remains inadequately understood and difficult to define accurately for Finite Element Method (FEM) simulations. Consequently, current simulations often use constant friction coefficients. In this study, friction coefficients for SAE 1045 are determined using a developed tribometer. A first friction model depending on the cutting velocity is then developed based on the obtained data and implemented in the FEM. Simulations were compared with corresponding experimental data. Within the CIRP Working group friction coefficients for SAE 1045 are determined from different tribometers and the data combined was used to evolve the friction model as a function of pressure, velocity and temperature.
