【摘要】 针对06Cr18Ni11Ti奥氏体不锈钢材料在深孔钻削过程中轴心线偏斜的问题,以理论分析、仿真分析和试验研究相结合的方法,通过数学建模将深孔轴心线偏斜问题转化为轴向力随孔深变化问题。基于ABAQUS有限元软件对06Cr18Ni11Ti奥氏体不锈钢的深孔钻削过程进行仿真,分析了该材料在深孔钻削过程中的轴心线偏斜机理,并进行了加工试验研究。研究结果表明:在转速相同的情况下,随着进给量的增大,理论轴心线偏斜的程度也变大,且理论轴心线偏斜量和实际轴心线偏斜量的误差最大为18.6%。该方法可以有效预防深孔钻削过程中的轴心线偏斜问题。更多还原

【Abstract】 In order to solve the problem of axis deviation of 06 Cr18 Ni11 Ti austenitic stainless steel material in deep hole drilling, by combining theoretical analysis, simulation analysis and experimental research, the problem of axial line deflection in deep hole is transformed into the problem of axial force varying with hole depth through mathematical modeling. The deep hole drilling process of 06 Cr18 Ni11 Ti austenitic stainless steel was simulated based on the ABAQUS finite element software, and the mechanism of the axis line deflection of the material in the deep hole drilling process was analyzed, and the machining experiment was carried out. The research results show that: under the same speed, with the increase of the feed, the degree of deflection of the theoretical axis line also increases; and the maximum error between the theoretical axis line deflection amount and the actual axis line deflection is 18.6%.This method can effectively prevent the axis deflection problem in the process of deep hole drilling.更多还原
