Figure 18: The ANN SPRT model's performance.

Regression coefficients close to one indicate that the developed ANN model could be used to predict the flank wear of SPRT when turning Inconel 718. Further, the accuracy of the ANN model was assessed through validatory experiments at different cutting conditions and machining times, excluding those used for model development. Using ANN and mathematical models, Fig. 20 compares experimental and expected flank wear under the cutting circumstances shown in Tab. 4. It is evident that predicted outcomes from ANN models agree more closely with experimental values compared to mathematical models.
