在1616车床上加工磁系组合件时,过去由于没有合理的选择钻头的前角和后角,轴向力较大,有时把原来装好的组合件也给顶串位了。为了减少钻削时的轴向力,防止破坏软铁与铜条的组合,用优选法选择了钻头的前角和后角。 In the 1616 lathe machining magnetic assembly, in the past due to the lack of a reasonable choice of bit rake and angle, the axial force is larger, and sometimes the original assembly is also given to the top of a string bit string. In order to reduce the axial force during drilling and prevent the combination of soft iron and copper bar from being damaged, the rake angle and relief angle of the bit were selected by the optimization method.
