Online identification and closed-loop control method for heat and mass transfer health state in titanium alloy processing

The invention discloses an online recognition and closed-loop control method for a heat and mass transfer health state in titanium alloy machining, and the method comprises the steps: obtaining fog drops for lubricating and cooling in titanium alloy machining through a gas-liquid two-phase spraying control system; the heat and mass transfer state in the titanium alloy machining process is changed by regulating and controlling the characteristics of lubricating and cooling fog drops; a data acquisition system is used for acquiring and reducing noise of various types of heat and mass transfer state data, a correlation dimension value is calculated, a multi-parameter multi-target database of the heat and mass transfer state data is established through a deep learning algorithm, the correlation dimension value calculated by the acquired data is compared with a correlation dimension prediction value in the database, and the correlation dimension prediction value is calculated. The health state of titanium alloy ma
