摘要: 在对螺旋棒铣刀铣削力建模中考虑了切削厚度变化对铣削力影响的指数关系、铣刀偏心对实际切削厚度、切入与切出角、铣削力波动的影响,并提出采用实测各刀齿铣削最大值比求解铣刀偏心和识别铣削力系数的方法。在考虑铣刀偏心因素的情况下仿真与实测的铣削力达到非常好的一致性。提出的铣削力仿真方法充分反映了铣削力的实际状态,提高了铣削力仿真精度。

Abstract: This paper presents a mechanistic model of milling forces for helical end mills. In the model the influence of exponential relationship of chip thickness variation on cutting force and the influences of cutter offset on effective chip thickness, entry end exit angles of cutting edges and variation in amplitude and wave form of milling forces are concerned. The computer algorisms are developed for to determine the cutter offset using the peak cutting force ratios of different cutting teeth in the measured milling force and to identify the milling force coefficients. The meansured milling forces obtained from milling tests. The milling force simulation approach presented in this paper improves the accuracy of simulation and provides the real situation of milling force.
