摘要
以45钢轴件为加工对象进行无磨料超声抛光工艺试验,优选工艺参数,探索各工艺参数对表面粗糙度的影响。试验结果表明,工艺参数对加工表面粗糙度影响顺序为进给量、超声波发生器的输出功率、抛光预压力和工具头半径;表面粗糙度值随进给量的增大而增大,而工具头半径、预压力和超声波发生器的输出功率对表面粗糙度的影响曲线为驼峰曲线,过大或过小的工艺参数均影响抛光效果。
Experiments of ultrasonic polishing the steel 45 without abrasive were carried out to optimize the processing parameters and explore the influence of each parameter on the surface roughness. The results indicate that the influencing order of processing parameters on machined surface roughness is feed rate, output power of ultrasonic generator, polishing preload and radius of tool head. The machined surface roughness increases with the federate, and the influencing curves of radius of tool head, preload and output power of generator on the surface roughness are humped, which means that too larger or too smaller processing parameters will weaken the polishing quality.
