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 pa-rameters that affect the bit vibration and surface roughness.The experimental results showed that the vi-bration of the drill increases with the increase of tool wear.The optimum cutting parameters of the drill vi-bration,feed rate and spindle speed,respectively,and the optimum cutting parameters of surface rough-ness,feed rate,spindle speed respectively have been given.
