The invention relates to an intelligent monitoring and alarm device and method of grinding fluid during optical ultra-precision machining. The intelligent monitoring and alarm device comprises a controller, a data collecting module and an alarm output module, wherein a liquid level value, a temperature value, a pressure value and a flow value of the grinding fluid which are allowed to be used under various working conditions of a grinding testing table are preset in the controller; the data collecting module is installed in the grinding testing table and electrically connected with the controller, and is used for collecting signals of the grinding fluid of the grinding testing table; the controller is electrically connected with the alarm output module, and the alarm output module and a control system of the grinding testing table are convertibly and electrically connected or disconnected; the controller compares the signals of the grinding fluid of the grinding testing table collectedby the data collecting module with an internal preset value to be allowed, the signals are lower than or higher than the preset value, the controller controls the alarm output module to give an alarm; and when a workpiece is processed, the alarm output module and the control system of the grinding testing table are electrically connected, the control system of the grinding testing table controlsa main shaft of the grinding testing table to lift and keep away from the surface of the workpiece so as to protect the workpiece.
Description
technical field [0001] The invention relates to the technical field of optical ultra-precision grinding, and more specifically relates to an intelligent monitoring and alarming device and method for grinding fluid in the ultra-precision grinding process of large-diameter optical elements. Background technique [0002] Using consolidated abrasive diamond grinding wheel and ultra-precision grinding technology to achieve precision forming of large-diameter optical components, it has the advantages of fast material removal rate, high forming precision, easy realization, stable defect control, and easy realization of automatic processing. During the processing, the diamond grinding wheel rotates at high speed, and the fine abrasive grains on the surface of the grinding wheel perform deterministic, trace and high-speed cutting removal on the workpiece. However, due to the brittle and hard characteristics of optical materials, a large amount of heat generated during the grinding pr...
