In ultrasonic precision machining, the correct and healthy use of the machining tool is particularly important. Therefore, whether the ultrasonic machining tool is in the optimal working state is also very important for the whole precision machining system, and the service life of the machining tool is related, and the machining quality of the machined part is directly influenced. This requires that the skilled person be able to accurately measure and master the data about the vibration frequency, amplitude and temperature of the ultrasonic machining tool under excitation so that it can be accurately assessed whether the relevant parameters of the tool during machining are normal or not, whether they are in an optimal working state or not. At present, related devices exist for measuring the vibration frequency, amplitude and temperature of an ultrasonic processing tool in China, but the measurement of the parameters is in an independent and single measurement stage, so that the vibration frequency, the amplitude and the temperature of the ultrasonic processing tool cannot be measured simultaneously and effectively, the measurement process is zero-crushing, precious time is wasted greatly in detection work, and the measurement work cannot be performed quickly and efficiently. Meanwhile, at present, a plurality of modes of measuring by handheld detection equipment still exist, which leads to a plurality of unavoidable human error in measurement, and the measurement result is inaccurate, so that the working state of the ultrasonic processing cutter is misjudged. Various phenomena show that a great deal of research space still exists in the related technology of ultrasonic processing cutter vibration frequency, amplitude and temperature measurement.
