摘要
精密小型叶轮具有结构紧凑、精度高要求、叶片间距小、叶片厚度小等特点。因此易造成叶轮尺寸超差、粗糙度超差、叶片变形等问题。叶片加工过程中需五轴联动,编程难度大,加工效率低,成为生产瓶颈。针对精密小型叶轮确定合理的加工方案、编程方案,利用数控加工仿真软件对整个加工过程进行仿真、优化,达到理想效果。
Precision small impellers are characterized by compact structure, high precision requirements, small blade spacing and small blade thickness. Therefore, it is easy to cause problems such as excessive impeller size, excessive roughness, and blade deformation. Five-axis linkage is required in the blade processing process, which is difficult to program and has low processing efficiency, which becomes a production bottleneck. A reasonable machining plan and programming scheme are determined for the precision small impeller, and the whole machining process is simulated and optimized by the numerical control machining simulation software to achieve the desired effect.
