In order to improve the keyway broaching process and verify the feasibility of vibration-assisted broaching process. an experimental study on a novel hydraulic vibration assisted broaching (HVAB) system with double-valve electro-hydraulic exciter (DVEHE) is proposed in this paper. The performances of HVAB at different excitation frequencies were compared from three aspects: (a) the cu... https://www.soiebiologique.com/
