Abstract Based on the theory of ultrasonic vibration design and ultrasonic vibration horn, a straight blade cutter
for ultrasonic assisted cutting of weak stiffness material was designed. The influence of length, thickness parameters of
the blade on the resonant frequency, amplitude magnification and longitudinal amplitude of the tool was analyzed. The effects
of the tool width and transverse direction and the distribution of lateral amplitude along the tool axis direction were
discussed. For the particular ultrasonic vibration system, the tool parameters with the best overall performance were determined.
The cutting edge simulation tool with different shape parameters was developed and tested on the same ultrasonic
vibration system. The conclusion of the simulation analysis was verified. The theoretical analysis was in accordance with
the experimental results. According to the optimum parameters determined by the theoretical analysis, the straight blade
cutter was developed and its vibration performance was tested. The conclusion of the study provided theoretical guidance
for the development of straight blade cutter for ultrasonic assisted machining.
