[0002] With the continuous development of the manufacturing industry, CNC machine tools are being used more and more widely in various fields. CNC machine tools have the advantages of high efficiency and high degree of automation, and can meet the needs of modern manufacturing for complex parts processing. In the process of CNC machine tool processing, cutting fluid plays a vital role. It can cool the tool and workpiece, lubricate the cutting area and remove chips, etc., thereby improving the processing quality and efficiency. With the continuous growth of the demand for CNC machine tool processing, the use of cutting fluid is also increasing. The traditional way of using cutting fluid is usually to discharge it after a one-time use, which not only causes a waste of cutting fluid, but also wastes a lot of water resources. The cutting fluid contains a variety of chemical substances in its ingredients. Discharging after a one-time use not only increases the production cost of the enterprise, but also pollutes the environment.

[0003] The application of efficient filtering technology, advanced cooling technology, precise concentration detection technology, intelligent control system, etc., makes the recycling of cutting fluid possible. With the continuous development of sensor technology and automation technology, the intelligence level of cutting fluid recycling control system is also constantly improving, which can realize real-time monitoring and automatic control functions, providing enterprises with more convenient and efficient services.

The personal information includes name, position, ID number and personal fingerprint parameters. The data center receives and stores the personal information and aggregates the personal information of each staff member into an employee information set. Each staff member logs in to the corresponding operation page through the control panel of each machine tool equipment.

If the actual cutting operation value is greater than the preset cutting operation value, an operation signal is generated and sent to the pumping device. After the pumping device receives the operation signal, the cutting fluid is extracted from the fluid storage tank and transported to the corresponding machine tool working area. After the cutting fluid completes the cooling, lubrication and chip removal working steps in the machine tool working area, a completion signal is generated and sent to the pumping device. After receiving the completion signal, the pumping device returns the cutting fluid to the filtering device.

The processed cutting fluids are received, and the temperature parameters of the processed cutting fluids are collected in real time through the temperature sensor to obtain the temperature parameter values ​​of the processed cutting fluids. The obtained temperature parameter values ​​are averaged to obtain the temperature average value, marked as DP, and then the temperature parameter values ​​of the processed cutting fluids are arranged from large to small to obtain the maximum temperature parameter value and the minimum temperature parameter value. The maximum temperature parameter value is subtracted from the minimum temperature parameter value to obtain the maximum temperature difference value, marked as DS. The contact area image of the cutting fluid and the environment is obtained through a high-definition camera, and the contact area value is obtained according to the contact area image of the environment, recorded as TY. The current ambient temperature value is obtained through the temperature sensor, recorded as TR, and the formula DH=TI×TY×(DP-TR) is used to calculate the ambient absorption temperature value DH, where TI is represented by the heat transfer coefficient, and the average temperature, maximum temperature difference and ambient absorption temperature value are obtained for calculation, and the formula is used to calculate. The temperature change value is obtained, where q1, q2 and q3 are preset proportional coefficients, i is the number of each machine tool equipment, and n is the total number of each machine tool equipment. The temperature change threshold preset in the data center is extracted, and the actual temperature change value is compared with the preset temperature change threshold. If the actual temperature change value is greater than the preset temperature change threshold, a cooling signal is generated and sent to the corresponding heat exchanger. The heat exchanger receives the cooling signal and generates a cooling instruction and sends it to the pumping module. The pumping module transports the coolant to the heat exchanger. The heat exchanger uses the circulating flow of the coolant to exchange heat with the cutting fluid to take away the heat until the cutting fluid returns to the standard temperature.

The equipment information includes the equipment production date and the equipment scrapping age. The data center receives the equipment information and stores it, and adds the production date of each machine tool equipment to the equipment scrapping age to obtain the corresponding scrapping time point of each machine tool equipment. As of the current system time point, the scrapping time point is subtracted from the system time point to obtain the scrapping period difference. If the scrapping period difference is a positive number, it means that the corresponding machine tool equipment has reached the scrapping date, and the corresponding machine tool equipment is marked as scrapped equipment, and the scrapped equipment is eliminated.

[0018] Compared with the prior art, the beneficial effects of the present invention are: improving the utilization rate of cutting fluid, realizing the recycling of cutting fluid through the synergistic effect of filtering, cooling and concentration adjustment modules, and greatly reducing the waste of cutting fluid.

If the match is successful, the operation authority of the corresponding machine tool equipment is obtained. If the match is unsuccessful, the current page is exited.
