The sensor can detect precision grinding conditions during the grinding process, and it can also estimate the wear rate of grinding tools. The sensor is based on the piezoelectri
2、c principle, and it can monitor the natural frequency and impedance of the grinding tool. The experimental results show that the sensor has high detection accuracy and can significantly improve the efficiency of the grinding process.IntroductionPrecision grinding is a key process in the manufacturin
3、g industry, and it is widely used in the production of high-precision parts. The quality of the grinding process is closely related to the accuracy, efficiency, and cost of the manufacturing process. However, traditional grinding methods often rely on operator experience and subjective judgments, wh
4、ich can lead to unstable quality and low production efficiency. Therefore, the development of online monitoring technology for the grinding process is essential.In recent years, with the development of sensor technology, various grinding process monitoring sensors have emerged. However, most of thes
5、e sensors cannot accurately monitor the abrasive particle size and wear rate of the grinding tool, which are important parameters for the grinding process. Therefore, a new type of abrasive particle online monitoring sensor is needed.Design and principle of the sensorThe new type of abrasive particl
6、e online monitoring sensor is based on the piezoelectric principle. The sensor is composed of a piezoelectric element, a grinding tool, and a data acquisition system (DAQ).During the grinding process, the piezoelectric element is placed on the surface of the grinding tool, and it can detect the natu
7、ral frequency and impedance of the grinding tool. The natural frequency of the grinding tool is affected by the abrasive particle size and the wear rate of the grinding tool. Therefore, the sensor can estimate the abrasive particle size and wear rate of the grinding tool based on the changes in the
8、natural frequency and impedance.Experimental resultsIn order to test the performance of the sensor, a series of grinding experiments were carried out on a precision grinding machine. The experimental material was 45# steel with a hardness of HRC60. The grinding wheel used was a CBN grinding wheel wi
9、th a particle size of 150 mesh.During the grinding process, the data acquisition system collected the natural frequency and impedance data of the grinding tool in real time. The experimental results show that the sensor can accurately monitor the natural frequency and impedance of the grinding tool,
10、 and it can estimate the abrasive particle size and wear rate of the grinding tool.Through data analysis, it was found that the abrasive particle size decreased gradually during the grinding process, and the wear rate of the grinding tool increased gradually. The sensor can accurately detect these c
11、hanges and provide timely feedback to the operator. Therefore, the sensor can significantly improve the efficiency and quality of the grinding process.ConclusionIn conclusion, a new type of abrasive particle online monitoring sensor based on the piezoelectric principle was designed and tested. The s
12、ensor can accurately monitor the natural frequency and impedance of the grinding tool, and it can estimate the abrasive particle size and wear rate of the grinding tool. The experimental results show that the sensor has high detection accuracy and can significantly improve the efficiency and quality
13、 of the grinding process. The sensor has great potential for application in the field of precision grinding.Moreover, the new type of abrasive particle online monitoring sensor has several advantages over traditional monitoring methods. First, it is a non-destructive and real-time monitoring method,
14、 which means that it can provide timely feedback to the operator and ensure stable quality of the grinding process. Second, the sensor can be integrated into the grinding machine, which simplifies the monitoring system and reduces the complexity of the operation. Third, the sensor can reduce the cos
15、t of grinding tools and improve the tool life by accurately estimating the wear rate of the tool and providing timely replacement.However, there are some limitations to the current sensor design. Since the piezoelectric material has a limited frequency response range, the sensor can only monitor the
16、 natural frequency and impedance of the grinding tool within a certain frequency range. In addition, the sensor is sensitive to external interference and may produce measurement errors in complex grinding environments. Further research is needed to improve the sensor design and reduce the measuremen
17、t errors.In conclusion, the development of the new type of abrasive particle online monitoring sensor is a significant step towards improving the efficiency and quality of the grinding process.
