A vibration reducing boring bar with variable damping is proposed as a solution to the issue of poor stability of boring bars during boring machining. This will enhance the stability of boring machining. Firstly, this article places a variable damping absorber in the cavity at the front end of the boring bar. An excitation coil, a mass block, and a cantilever beam make up the absorber structure. It contributes to damping adjustment by adjusting the excitation coil's energizing voltage, which alters the damping force on the mass block. On this basis, establish a dynamic model and analyze the damping and magnetic field of the variable damping absorber. Simultaneously building a vibration damping boring bar system platform based on LabVIEW to monitor and control the vibration status of the boring bar. Ultimately, performance testing of the absorber and boring experiments confirmed the viability of the vibration damping boring bar. The results showed that the maximum vibration acceleration of the vibration damping boring bar decreased by about 34.7%. It has been proven that the variable damping vibration reduction boring bar has good vibration reduction effect.
