航空精密小叶轮的零件结构特殊,尺寸规格小,叶片极薄,叶片间空间小,圆角小,精度要求高,加工中极易出现断刀、尺寸超差、光度超差等问题,加工难度大,已成为实际生产中的瓶颈。主要针对这种精密小叶轮零件的机械加工部分,确定工艺方案,充分利用数控设备,确定合理的走刀路线,运用UG建模,后置处理生成加工程序,反复调试、试切,优化数控程序,最终实现精密小叶轮的数控加工,并且该数控加工技术可以推广到其它十余种同类零件的加工中,具有一定的工程实用价值。
Aviation precision small impeller parts special structure, small size, thin blade, blade space is small, small fillet, high precision, prone to cutting knife in the process, the size of ultra-poor, photometric ultra-poor and other issues, the processing difficulty Large, has become the bottleneck in the actual production. Mainly for this precision small impeller parts machined part, to determine the process plan, make full use of numerical control equipment, to determine a reasonable path to go through the use of UG modeling, post-processing to generate machining procedures, repeated debugging, trial cutting, optimization of CNC programs , Finally realize the precision small impeller CNC machining, and the CNC machining technology can be extended to the processing of other more than 10 kinds of similar parts, has a certain engineering value.
