Abstract

In this work, cutting forces in conventional and ultrasonic-vibration assisted turning are estimated using an inverse method to evaluate the velocity-dependent friction and fracture toughness based on a few tests in conventional turning. The inverse methodology requires the data on cutting and feed forces at two specified cutting speeds. Analytical expressions are employed to estimate the cutting forces in conventional as well as ultrasonic-vibration assisted turning. The suggested method was verified with experimental data. The validation of the direct model with the finite-element results available in the literature was also carried out. A sensitivity analysis revealed a significant effect of friction on cutting forces. Thanks to its simplicity, the proposed procedure may find a good application in industrial practice.
