Prediction of CNC Machining Performance Using A.I Via Neural Nets.Production EngineeringEng. Mahmoud Mohammed Ata MahmoudProf. Dr. Abdel-Razek A. Aboul-NourAssociate Prof. Dr. Samir N. ShoukryAssociate Prof. Dr. Ibrahim A. EI-Sonbaty114English1996Faculty of Engineering, Zagazig UniversityApplying the neural networks in the prediction of themachining performance. The study includes:-- Machining a munber of specimens with differentcutting conditions and pre-tool wear.- Training different back-propagation neural nets’structures for the resulting surface roughnessparameters and the flank tool wear.- Integrating the trained neural networks togetherwith another neural net, to get the vibration level,..
