【摘要】 切屑形态是影响深孔加工排屑的关键性因素。通过对40Cr Mo A进行钻削的过程,研究错齿BTA深孔钻3个切削刃(中心刃,中间刃和边刃)产生的切屑形态,计算切屑的变形系数;分析在同一切削条件下错齿BTA深孔钻产生3种不同切屑形态的原因,为深孔钻削40Cr Mo A切削参数以及刀具的优化打下基础。更多还原

【Abstract】 Chip morphology is the key factor of influencing the deep hole processing chip removal.Through the process of drilling 40 Cr Mo A, the chip morphology produced by three cutting edges(center edge, middle edge and side edge) of stagger BTA deep hole drilling was studied, and the deformation coefficient of chip was calculated. Under the same cutting condition, the reason about three different chip shapes generated by stagger BTA deep hole drill was analyzed, which laid the foundation for the optimization of deep hole drilling 40 Cr Mo A cutting parameters and tool.更多还原
