Decision-making process in manufacturing environment is increasingly difficult due to the rapid changes
in design and demand of quality products. To make decision making process (selection of machining
parameters) online, effective and efficient artificial intelligent tools like neural networks are being
attempted. This paper proposes the development of neural network models for prediction of machining
parameters in CNC turning process. Experiments are designed based on Taguchi’s Design of Experiments
(DOE) and conducted with cutting speed, feed rate, depth of cut and nose radius as the process parameters
and surface roughness and power consumption as objectives. Results from experiments are used to train
the developed neuro based hybrid models. Among the developed models, performance of neural network
model trained with particle swarm optimization model is superior in terms of computational speed and
accuracy. Developed models are validated and reported. Signal-to-noise (S/N) ratios of responses are calculated
to identify the influences of process parameters using analysis of variance (ANOVA) analysis. The
developed model can be used in automotive industries for deciding the machining parameters to attain
quality with minimum power consumption and hence maximum productivity.
