Abstract

This paper investigates the broaching process of phosphor-bronze (C54400) under different cutting conditions, and the influential factors on cutting force and surface quality are studied. The simulated cutting force implementing the force model based on the energy components also agrees with the results of experiments. In the first part, different cutting velocities of VC = 5, 10, 15, and 20 m/min are studied. In the second part, harmonic vibrations in the form of a sine wave with precise amplitude (A = 1 m/min) and frequencies (F = 55, 65, 85, and 95 Hz) are added in the direction of the cutting velocity. The results revealed that an increase in the cutting velocity from 5 to 20 m/min results in a 40% enhancement in surface quality and a 20% decrease in the cutting force. Additionally, harmonic vibrations of higher frequencies can also contribute to a 35% higher surface quality and a 20% lower cutting force. This study will ultimately improve productivity in industries where broaching is considered the main manufacturing approach, such as automotive and aerospace, in which precision and accuracy are of paramount importance.

谐波振动拉削(HVB)中切削力和表面质量的研究
研究了磷青铜(C54400)在不同切削条件下的拉削过程,研究了影响拉削力和表面质量的因素。实现基于能量分量的力模型的模拟切削力也与实验结果一致。在第一部分中,VC的不同切削速度 = 5、10、15和20 m/min。在第二部分中,正弦波形式的谐波振动具有精确的振幅(a = 1. m/min)和频率(F = 55、65、85和95 Hz)在切割速度的方向上相加。结果表明,切削速度从5提高到20 m/min导致表面质量提高40%,切削力降低20%。此外,更高频率的谐波振动也有助于提高35%的表面质量和降低20%的切削力。这项研究将最终提高拉削被认为是主要制造方法的行业的生产力,如汽车和航空航天,在这些行业中,精度和准确性至关重要。
