摘　　要：深孔镗削过程中,设置合理的切削参数可有效减小切削系统的振动。基于矢量法建立多刃均布式深孔镗刀的切削角度模型,利用Pro/E建立几何模型并生成中性几何文件,通过Ansys有限元法,计算不同切削条件下,镗刀的受力情况,分析其最大应力应变曲线,确定出合理的切削参数。It is effective to decrease the libration of the machining system by choosing some appropriate cutting parameters in the process of the deep hole boring.The model of cut angles for the equispaced multi-edge deep hole boring tool is built by the vector graphics.In order to analysis the force of this kind of boring tool,two softwares are applied,one is Pro/E applied to build a normal geometry file,the other one is a kind of finite element software-Ansys.After analysis by Ansys,the result can be used to show some various load-carrying capabilities of the boring tool under different cutting resistances and the appropriate cutting parameters can be chose by analyzing its curve of the maximum stress-strain.
