Abstract: In the present work, cutting and feed forces in the dry and air-cooled turning of grey cast iron with mixed oxide ceramic cutting tool are modelled. The radial basis function neural network is used for this purpose. The forces could be predicted with a reasonable accuracy. Indirect estimation of tool wear based on the force measurements is also attempted. It is observed that rate of change of tool wear with respect to forces can be used for the estimation of the tool wear. However, the prediction can be made only in a probabilistic sense. The replicate experiments justify it.
