In order to develop higher precision and more realtime grinding condition monitoring system,the principle of grinding condition monitoring with sound emission technology was researched.On the basis of module development of the grinding condition monitoring system based on AE,overall structure of the dualthread was designed through local variable and producer/consumer module in LabVIEW.Reliability and accuracy of these two dualthread methods were compared through experiment.The experiment results show that the dualthread program of the grinding condition monitoring system designed by producer/consumer module has advantages on the reliability and accuracy.
