Abstract

For an internal cooling system for precision turning and a control method thereof, internal cooling channels are machined in turning tool, and internal cooling sleeves are used to realize the communication between each hydraulic branch circuit and internal cooling channels of turning tool; a tool contact area calculation model is established to master the change rule of the contact state in whole-domain turning process of a curved surface component; the temperature and flow rate of a cooling medium at a liquid outlet of an air-cooled water cooler are set according to the material property and cutting conditions of the curved surface component; an electromagnetic control circuit is used to control the on-off of electromagnetic directional valves, so as to adjust the conduction sequence and action time of each hydraulic branch circuit, and further realize the localized, directional and accurate cooling of a curved surface component cutting tool.
