In this paper, single correct and three defective states for the cold headed fasteners production technological process are detected. Computational intelligence methods are used for this purpose: single decision tree, probabilistic neural network, support vector machine, multilayer perceptron, linear discriminant analysis and K–Means clustering. The predictor variables are taken in time and frequency domain. The row data sets consist of sampled signals of the real process collected in fasteners manufacturing company. The prediction ability determined by 10-fold cross validation is investigated by means of accuracy, sensitivity and specificity. The results show the superiority of probabilistic neural network and support vector machine classifiers. The average accuracy is over 98%.
