摘 要: | 钛合金航空薄壁结构件在铣削过程中受力形式复杂,切削力较大。超声椭圆振动切削的特点是切削刀具的刀尖按椭圆轨迹运动,进行高频间歇性切削,有助于降低切削力。铣削时改变切削参数将对切削力产生不同影响。采用自行研制的螺纹式椭圆激励式超声振动铣削刀柄装置,针对钛合金薄壁件进行实验,结果表明:相较于普通铣削,随着每齿进给量的增大,超声椭圆振动铣削均可减小钛合金薄壁件在铣削加工过程中的切削力,降幅可达35%以上。

Influence of Ultrasonic Elliptical Vibration Milling Parameters with Titanium Alloy on the Cutting Force |

Abstract: | In the course of milling,the force form of titanium alloy thin-wall structural parts is complex and the cutting force is large.The feature of ultrasonic elliptical vibration cutting is that the cutting tool tip moves in accordance with elliptical trajectory,and high frequency intermittent cutting is helpful to reduce the cutting force.In milling,cutting parameters have different effects on the cutting force.A self-developed ultrasonic vibration milling device is used to the experiment with titanium alloy thin-wall parts.The experimental results show that compared with the common milling,the ultrasonic elliptical vibration milling can reduce the cutting force in the process of titanium alloy thin-wall parts milling with the increase of feed per tooth,and the decrease rate can reach more than 35%. |
