以主轴转速、进给速度、静压力和滚压次数为影响因素，设计四因素四水平正交实验和单因素实验，探究不同加工参数对材料表面粗糙度和表面形貌的影响规律。研究结果表明：超声滚压可使材料表面粗糙度最小达到0.186μm；在研究工况下，超声滚压处理后的工件表面对比未滚压工件，粗糙度显著降低，降幅区间为60%～80%，材料表面光滑；随主轴转速的增加，表面粗糙度先增大再减小，随静压力的增加变化较为稳定，随滚压次数的增加先减小后增大，随进给速度的增加先增大后减小。极差分析表明了主轴转速对表面粗糙度影响最大，其次是进给速度和滚压次数，静压力的影响最小，在主轴转速为1 000 r/min、进给速度为40 mm/min、静压力为600 N、滚压2次的滚压工况下，材料可以获得最好的滚压表面质量。

The four-factor four-level orthogonal experiments and single-factor experiments were designed with spindle speed,feed rate,static pressure and rolling times as the influencing factors to investigate the influence of different machining parameters on the surface roughness and surface topography of the material. The research results show that ultrasonic tumbling can make the surface roughness of the material reach a minimum of 0.186 μm;under the research working conditions,the roughness level of the workpiece whose surface is turning smooth after ultrasonic tumbling treatment,is significantly reduced in the range of 60% to 80% compared with the unrolled workpiece;with the increase of spindle speed,the surface roughness increases and then decreases;with the increase of static pressure,the change in roughness is more stable;with the increase of rolling times,the roughness level of surface decreases and then increases;with the increase of feed speed,the roughness level increases and then decreases. The extreme difference analysis shows that the spindle speed has the greatest effect on the surface roughness,followed by the feed rate and the number of rolls,and the static pressure has the least effect. The best rolled surface quality of the material can be achieved under the rolling conditions of spindle speed of 1 000 r/min,feed rate of 40 mm/min,static pressure of 600 N and 2 rolls.
