摘要：为了研究枪钻深孔加工中加工参数对孔圆度误差的影响，对枪钻加工切削参数进行优化。本文提出了一种基于田口法的参数优化方法，着重研究不同转速、进给速度和加工深度对孔圆度形貌的影响。并通过对比实验研究，分析加工孔圆度误差的优劣，从而确定优选的加工条件范围。通过对各因素信噪比极差值的求解，确定不同加工参数对孔圆度误差的影响程度，通过响应曲面法得出加工参数最优范围，实现了提高枪钻深孔圆度及加工的目的，为控制因素的分析和切削参数的优化研究提供了新的思路。

Abstract:In order to study the influence of processing parameters on roundness in deep hole drilling，and to optimize the parameters of processing parameters，a parameter research method based on Taguchi method is proposed.The analysis of rotation speed，feed speed and processing depth are carried out.Through the comparative and analysis of the roundness，the best condition is determined.The influence degree of every factors on the roundness is determined by the range of signaltonoise ratio and the optimal range of the parameter is defined by RSM.The purpose of improving the roundness is achieved and a new kind of method of optimizing the cutting parameters and analyzing the control factors is provided.
