三切削刃BTA深孔钻钻削过程研究

通过试验对3个切削刃BTA深孔钻削过程进行了研究,主要分析了在特定的深孔条件下切屑变形和钻削力的情况.通过对测试系统所得到的试验数据进行评估和证实,阐述了BTA深孔钻轴向力的组成和切屑变形、刀具磨损以及钻削力之间的关系.研究结果表明,钻头的内刃在切削过程中产生的切屑变形最大,3个切削刃(内刃、中间刃、外刃)的切削力和切屑变形的总体变化趋势是相同的.

Study on Process of BTA Deep Hole Drilling with Three Cutting Edges

By the study on experiment of BTA deep hole drilling with three cutting edges,it analyses the status of drilling forces and chip deformation in deep hole situation in particular.Based on the evaluation and validation of experiment data from acquisition system,it describes the consist of the axial force and the relations of drilling forces,tool wear and chip deformation.The results show that the chip deformation of the inner edge is the largest in the drilling process,and the general change tendency of the d...
