The Taguchi’s orthogonal arrays is first used to plan the experiments in this research; the considered factors included the spindle speed, feed rate and the out point cutting angle, inner point cutting angle, position of the point, outer rake angle and inner rake angle of the tool geometry. The experiments will be done by gun-drill machine and the roughness in every interval of hole wall will be measured. The distributing value of surface roughness in every deep hole is expressed as the average and the standard deviation from the statistical viewpoint and the Abductive Networks is used to establish the models of averages and the standard deviations between the machining parameters and the tool geometry. At least the simulated annealing algorithm is used to optimize the machining parameters and the tool geometry so that the optimization of surface roughness of the hole wall in the whole deep hole can be achieved. The experimental results show that the combination of the optimum parameters for gun drilling can obtain the better and more uniform surface quality of the hole wall.
