TL;DR: The machinability of superalloy Inconel-800 has been investigated by performing different turning tests under MQL conditions, and MQL was found to be a better cooling technique when compared to the dry and the flood cooling.
Journal ArticleDOI
Artificial neural network based tool condition monitoring in micro mechanical peck drilling using thrust force signals
TL;DR: In this article, an Artificial Neural Network (ANN) model was developed to fuse thrust force, cutting speed, spindle speed and feed parameters to predict the drilled hole number, which was shown that the error of hole number prediction using ANN model is less than that using a regression model.
Journal ArticleDOI
A hybrid modelling approach towards prediction of cutting forces in micro end milling of Ti-6Al-4V titanium alloy
TL;DR: In this paper, a hybrid approach for prediction of cutting forces in micro end milling of titanium alloy Ti-6Al-4V was proposed, where cutting force coefficients were extracted by simulating the cutting process for a series of undeformed chip thickness (UCT).
Journal ArticleDOI
Artificial neural network based prediction of drill flank wear from motor current signals
TL;DR: The accuracy of the prediction of drill wear using neural network is found to be better than that using regression model.
Journal ArticleDOI
