摘要
这里研究了低频振动铣削对3Cr13不锈钢铣削力变化的影响。基于对工件和刀具轨迹的运动学分析,对比分析了低频振动铣削与普通铣削的刀具轨迹变化情况,结果表明振动铣削影响了工件-刀具间的相对运动轨迹。采用单因素试验法研究了沿工作台进给方向对工件施加低频激励时不同参数对铣削力的影响规律。试验结果表明低频振动铣削可以减小铣削力,并且铣削力大小与顺/逆铣、激振频率、电压,以及机床主轴转速有关,在相同切削条件下顺铣比逆铣产生的铣削力小。
This paper addresses the influence of the low frequency vibration assisted helical milling on the milling force variation of 3 Cr13 stainless steel.Based on the kinematics analysis of the workpiece and cutter trajectory,the variation of workpiece and cutter trajectory for both low-frequency vibration assisted helical milling and common milling were compared and analyzeded.The results show that vibration milling affects the relative motion track between workpiece and cutter.The variation of milling force under different parameters was researched by single factor orthogonal design methed while low-frequency stimulate was applied to the workpiece along the direction of the workbench feed.Results of the study shown that the low frequency vibration milling can reduce the milling force,and the milling force is related to forward/reverse milling,vibration frequency,vibration voltage and speed of the machine tool.In the same cutting conditions,the milling force produced by forward milling is smaller than that by reverse milling.
