摘　　要：以硬质合金钻头对AISI304不锈钢进行田口正交阵列实验,采用激光多普勒振动仪(LDV)、SJ-301便携式表面粗糙度测量仪分别测取钻头振动和钻孔内圆表面粗糙度。实验结果使用方差分析,确定影响钻头振动和表面粗糙度的显著切削参数。实验结果表明,钻头的振动随着刀具磨损程度的增大而增大,最终确定了钻头振动的最佳切削参数水平、主轴转速,以及表面粗糙度的最佳切削参数水平、进料速率、主轴转速等参数。The orthogonal array experiment of AISI304 stainless steel was carried out in this paper with a cemented carbide bit.The bit vibration and the surface roughness of the inner circle of the drill hole were respectively collected by the laser Doppler vibrometer(LDV) and the SJ-301 portable surface roughness meter.The experimental results were analyzed by variance analysis to determine the significant cutting parameters that affect the bit vibration and surface roughness.The experimental results showed that the vibration of the drill increases with the increase of tool wear.The optimum cutting parameters of the drill vibration,feed rate and spindle speed,respectively,and the optimum cutting parameters of surface roughness,feed rate,spindle speed respectively have been given.
