Resumen

In this work, a study on the dry turning process of UNS A92024 alloy has been carried out. This study has been achieved on the basis of the analysis of the surface finishing of the machined pieces in terms of roughness parameter, Ra, as a function of cutting speed, v, and feed, f. The aim of this work has been devoted to establish Ra=Ra(v,f) parametric relations. Two steps have been followed in order to obtain these relations. Thus, in a first step, Ra(v) and Ra(f) potential curves have been fitted to experimental data using a linear fitting in the log-log plane. After this, in a second step, those curves have been treated as Bizier curves to construct a Coons surface Ra(v,f). A mathematical expression of this surface has been obtained by fitting (v,f,Ra) experimental data to a combined Ra(v,f) potential model. The obtained parametric relation can thus be used to predict the surface quality of the turned pieces when different values of cutting speed and feed are applied.
