摘　　要：在铣削加工阶段融合了超声方法,有助于改善铣削质量并提升加工效率。构建了相应的实验方案对合金板加工过程开展验证,研究结果表明:超声铣削可以稳定减小粗糙度,适当提高切削速度不会对粗糙度值比率减小造成影响。相比较常规加工,采用超声加工表面存在超声频冲击作用形成的致密纹理,形成了更均匀单齿加工表面峰谷,峰谷差值保持稳定状态。测试期间合金板加工载荷包括切入、稳定超声切削、稳定常规切削及切出阶段。超声铣削可以稳定降低让刀量,使原本连续性刀齿加工模式转变成脉冲切削,引起刀具切削角度发生动态变化,形成更小去除厚度。该研究采用超声振动铣削方法可以显著减小加工表面粗糙度并实现刀量参数的准确分析。The ultrasonic method integrated in the milling process can help to improve the milling quality and enhance the machining efficiency.A corresponding experimental scheme was constructed to verify the machining process of alloy plate.The results show that ultrasonic milling can reduce the roughness stably,and proper increase of cutting speed will not affect the reduction of roughness ratio.Compared with conventional machining,the ultrasonic machining surface has dense texture formed by ultrasonic impact,forming a more uniform single tooth machining surface peak valley,peak valley difference maintained a stable state.The machining loads of alloy plates during the test period include cutting in,steady ultrasonic cutting,steady conventional cutting and cutting out stages.Ultrasonic milling can stably reduce the amount of cutting,make the original continuous cutting mode into pulse cutting,resulting in dynamic change of cutting Angle,forming a smaller removal thickness.In this study,the ultrasonic vibration milling method can significantly reduce the machining surface roughness and realize the accurate analysis of cutting parameters.
