摘　　要：GH4169合金由于其众多优良的性能,在航空航天等领域得到广泛应用。但GH4169合金属于典型的难加工材料,具有塑性优良、硬度大等特点,深孔钻削时易出现不断屑和堵屑情况,孔轴心线易发生偏斜等现象。该试验针对GH4169合金,使用BTA系统进行深孔钻削试验,分析在固定切削参数下,切屑形状、切屑厚度、切屑宽度、切屑压缩率和切屑容屑系数的变化规律,以及钻削初始进给量对孔轴心线偏斜的影响。GH4169 alloy has been widely used in aerospace and other fields due to its many excellent properties.GH4169 alloy is a typical difficult to machine material with excellent plasticity and high hardness.It is easy to have continuous chip and chip plugging during deep hole drilling,and the hole axis line is prone to skew.Based on GH4169 alloy,the deep hole drilling experiment was carried out by using BTA system.The changing rules of chip shape,chip thickness,chip width,chip compression ratio and chip capacity coefficient were analyzed under fixed cutting parameters,and the influence of initial drilling feed rate on hole axis deflection was also analyzed.
