摘　　要：通过BTA深孔钻削加工过程的实验,探讨了其切削机理,主要研究了BTA钻头切削部几何角度和切削用量对切屑变形的影响。实验结果显示,中心切削刃切下的切屑变形最大,各切削刃对切屑变形的影响趋势基本相同。本实验研究丰富了深孔加工的切削机理,为优化深孔加工的切削参数奠定了基础。ln this paper,the cutting mechanisms are investigated in boring an d trepanning association(BTA)deep hole drlling processes,and the effects of the cutting edges geometric angles cutting parameters are focused on chip deformatio n.It is found that the chip deformation cut by center edge is the largest,and ch ip deformation tendency cut by the edges is about the same.
