摘　　要：通过内排屑深孔钻削加工过程的实验 ,讨论了切削变形和钻削切削力与钻头切削部几何参数、切削用量等的关系 ,并得到了切削力的经验公式。实验表明 :各段切削刃对切屑变形的影响趋势基本相同 ,为内排屑深孔钻切削机理研究、切削参数数据库建立和进一步开发在线检测系统奠定了基础。In this paper, the relation between the chip deformation and cutting axial forces with cutting tool geometric parameters and cutting parameters are discussed, and the empirical formula is received. It is found that the chip deformation cut by center edge is the largest, and chip deformation tendency cut by the edges is about the same. This research laid down a solid basis for cutting mechanisms, cutting parameter database and further developing an on-line monitoring and control system for BTA deep hole drilling processes.
