The cutting parameters were planned and experimented using the Taguchi orthogonal table, where five processing parameters were linear velocity, feed rate, cutting depth, cutting distance and tool path, with each parameter having four levels. The workpiece surface roughness Ra and flank wear VB were measured following the experiment, with minimizing the target functions as the objective. The optimal parameter combination was sought for each target function. The results indicated that the optimal parameter combination led to a surface roughness (Ra) of 0.101μm, which met the polishing level requirement for processing stainless steel surface, and was achieved at a linear velocity of 550 m/min, a feed rate of 2300 mm/min, a cutting depth of 0.4 mm, and a cutting distance of 0.25 mm, with the milling tool path being bi-directional reverse. The optimal parameter combination resulted in a flank wear of 0.0091 mm, which was achieved at a linear velocity of 550m/min, a feed rate of 2100 mm/min, a cutting depth of 0.8 mm, and a cutting distance of 0.15 mm, with the milling tool path being unidirectional reverse. The results of this study was helpful in increasing the processing quality of high-speed milling of 304 stainless steel to the polishing level, which reduced the subsequent processing time, increased productivity and lowered processing costs.
