Abstract：

For the problem of precision shearing cutting of bar, a kind of rotary high-speed precision shearing cutting method was given. Then, the structure designs of rotary precision shearing cutting machine and feeding structure were completed, and the experiment platform was set up. Furthermore, the cutting tool was optimized by numerical simulation, and the cutting efficiency was controlled by using rotary impact and stress concentration effect of bar surface notch and changing the rotary speed of cutting tool through the converter. Finally, the cutting experiment was carried out for the stainless steel bar with Φ8 mm diameter, and the cutting results were analyzed comparing with that of the traditional method. The experimental results show that the method is feasible to meet the requirement of various material for bars with medium small diameter in the industry.
