Abstract: The objective of this paper is to develop artificial neural networks (ANN) and case-based reasoning (CBR) models to predict the tool life and the tool-shim interface temperature during turning of different alloy steel materials. The tool life of multicoated carbide, cermet and alumina inserts, and the temperature (measured by placing a thermocouple between the tool and shim in the tool holder) under various turning conditions are experimentally determined. Further, the experimental values are used to develop the prediction models based on ANN and CBR. Twenty sets of validation experiments are conducted to evaluate the performance of the prediction models. The prediction models are compared based on the statistical measures such as mean absolute percentage error (MAPE), root mean squared error (RMSE) and the correlation coefficient (R), and it is confirmed that CBR model is superior to ANN model for the machining process considered.
