Application of Artificial Neural Network for Prediction of Process Parameters of the Machining Processes
The objective of this research work is to apply the Artificial Neural Network (ANN) technique to the prediction of process parameters effectively to take the advantage in today's highly competitive world where manufacturing costs are sharply increasing due to increased cost of the raw materials, manpower and energy; short duration between demand and supply, challenge of reducing global warming, carbon footprint, environmental impact due to manufacturing activities. The surface finish plays a very vital role in the functioning of any component in the system. Therefore, in this study, the output parameter is surface roughness while three main process parameters speed, feed and depth of cut of machining process are input parameters which are responsible for obtaining desired surface finish on the work surface. The cutting tool parameters could be assumed to be constant because of a very high hardness ratio of tool to work material. The surface roughness of the machined work pieces was measured using a surface roughness tester. For the ANN software, the input parameters were speed, feed and depth of cut while the output parameter was surface roughness. To predict the surface roughness, the ANN model has been configured through feed forward back-propagation network and also a neural fitting tool has been used for the experimental data for the prediction of the resultant surface finish.
