Experimental Prediction Model for Roughness in the Turning of UNS A97075 Alloys

Abstract:

In this work, a study of the influence of the cutting parameters on superficial quality of dry-turned UNS A97075 test bars has been carried out. The superficial quality has been evaluated trough the arithmetical average roughness, Ra. In addition, the evolution of Ra as a function of the axial machining length has been analyzed. In order to do this, a set of machining tests has been performed under different combinations of cutting speed and feed. The experimental data have revealed a high sensitivity to change of Ra with feed, whereas this sensitivity is lower with cutting speed. On the other hand, a tendency to decrease Ra with the axial machining length has been found. Finally, an experimental prediction model for Ra has been developed. This model allows predicting the value of Ra as a function of the cutting parameters and the machining time.
