摘要
根据超声波振动车削加工原理,第一步通过逐点单因素试验对超声振动切削下细长轴不同位置处表面粗糙度随切削用量的变化进行了研究,确定了不同切削因素变化下细长轴表面粗糙度的极值位置;第二步通过正交试验研究了超声振动车削细长轴时切削用量对工件整体平均表面粗糙度的影响,并与普通切削进行了对比试验。试验结果表明:超声波振动车削能够显著改善细长轴加工后的表面粗糙度。同时研究了各切削用量对表面粗糙度的影响规律,并对超声振动切削参数进行优化,得出试验最佳切削参数。
According to the principle of ultrasonic vibration turning, the first step is to study different position changes of surface roughness with cutting parameters under ultrasonic vibration turning of slender shaft by the test of single factor, and determining the extreme position of surface roughness with the slender shaft changes in different cutting conditions. The second step is to study the influence of cutting parameters on the overall .average surface roughness of workpiece under ultrasonic vibration turning of slender shaft by orthogonal test design, and compared with the conventional cutting. The experimental results show that ultrasonic vibration turning slender shaft processing can signifwantly improve the surface roughness. At the same time, the influence laws of cutting parameters on the surface roughness are investigated, and finding out the optimal cutting experimental parameters.
