Abstract: In this paper, a neural network model (ANN) was created to predict the cutting forces in turning process for a new tool. A dynamometer was used to measure the static and dynamic cutting forces during the machining process. AISI 4140 steel was used as the work piece material due to its common application in machining industry. Cutting force, thrust force and radial force were measured for three combinations of cutting speeds (V), feed rates (f) and cutting depths (d). The tool angles were kept constant throughout the experiments. Full factorial method was used to design the experiments. For establishing the prediction model, a back propagation network (BPN) was developed with two layers and five neurons. Experimental results were compared with the predicted results of the neural network model (NN). The R² values for training and test data were obtained 0.9992 and 0.9985 respectively.
