Application of ANN in Milling Process A Review

El-Mounayri et al. developed an ANN model for prediction of cutting forces in a ball end milling process. Radial basis was applied for its advantages from the view of convergence speed. The networks had four inputs and outputs with single hidden layers. The input parameters were spindle speed, feed rate, and axial, and radial depth of cuts while the outputs were maximum force, minimum forces
