This paper develops a vibration tapping torque testing machine based on ARM embedded system.In the process of vibration tapping,multiple functions such as multi-axis linkage interpolation,real-time observation,torque change recording and display are realized.Combining the filtering algorithm and fast fourier transform,the torque change curve is analyzed,processed,and stored.Through the intuitive representation of the data and the curve,it provides an accurate and reliable basis for the study of the torque change law of vibration tapping.It has a good reference in the research and application of the vibration mode,the composition of the process parameters,and the characteristics of the cutting fluid that affect the tapping torque.
