Embodiment Construction
[0039] The present invention is now explained in detail in conjunction with the embodiments and the accompanying drawings.
[0040] The invention proposes a load-energy efficiency evaluation and monitoring method of a numerically controlled machine tool for energy saving and emission reduction. The schematic flow chart of the inventive method is as figure 1As shown, first, with the help of RFID tags and RFID readers attached to the parts, the actual number of parts processed by the CNC machine tool within a given period of time can be obtained by perception. Then, according to the available time of the CNC machine tool and the ideal processing time of the parts within a given time period, the theoretical number of parts processed by the CNC machine tool is calculated. Based on the actual number of parts processed by the CNC machine tool and the number of theoretical parts processed, the load rate of the CNC machine tool is calculated. The energy consumption value of a single...

The invention discloses a numerically controlled machine tool load-energy efficiency evaluation and monitoring method for energy saving and emission reduction. In this method, the load rate of the CNC machine tool is calculated by obtaining the actual number of parts processed by the CNC machine tool and the number of theoretically processed parts within the evaluation period. Then, by obtaining the time waste value of the CNC machine tool and the standby power of the machine tool, the energy waste value of the machine tool is calculated. Further calculate the actual processing energy consumption of a single part, combined with the ideal processing energy consumption of a single part, calculate the load-energy efficiency of the CNC machine tool. Based on the load rate model and load-energy efficiency model of CNC machine tools obtained above, the relationship model between load-energy efficiency and load rate of CNC machine tools is constructed. Based on the above evaluation model, the load-energy efficiency of CNC machine tools is monitored and the alarm is exceeded. The method of the invention is a practical and effective method for evaluating the load-energy efficiency of the numerically controlled machine tool scientifically and can control the load-energy efficiency within the required range.
