Monitoring of Flow Resistance and Temperature Rise of Spindle Coolant and Early Warning Criteria for Machine Tools

Abstract

Since the industrial revolution in the eighteenth century upgrading productivity has been the focus of innovation in industry At this stage it has been developed to Industrial 4 0 that is we can combine the cyber physical system and intelligent integrated sensory control system with industrial production and manufacturing which can use the big data and cloud to make the machine tool highly automated and automatically eliminate production obstacles In order to improve the machining accuracy and normal operation of the machine tool we must rely on the monitoring system Therefore this thesis uses the experimental method to monitor the flow resistance and temperature rise of spindle coolant A similarity method is used to establish the cooling channel to simulate the cooling channel inside the spindle of the machine tool Moreover we install a pressure gauge and a flow meter to monitor the flow resistance change in order to monitor working conditions and analyze At the same time the enameled wire is wound around the circulating flow channel we established simulating the heat generated by the bearing and the coil and attaching the thermocouple on the surface of the flow channel to observe the temperature distribution of the flow channel Meanwhile we also use ANSYS to simulate the wall temperature distribution and compare the results with the actual industry reference indicators to analyze the relationship between the wall temperature and the fluid temperature of the flow channel and determine whether the uniformity of the temperature distribution of the pipe wall can be reflected by monitoring the inlet and outlet fluid temperature difference
