| 中文摘要: |
| 由于整体叶轮构造复杂，加工精度要求严格，其叶片的型面为自由型面并有一定的扭曲，同时叶片内流道较窄，为此在加工时很容易出现过切、碰撞、干涉等现象，加工难度大。结合工程应用，设计了整体叶轮的数控成形整套加工方案，并基于 UG 10.0 软件的 CAD/CAM 功能模块，重点研究了叶片成形过程仿真，验证了方法的可行性。所提出的数控成形加工方案，经仿真验证叶轮能够获得很好的成形， 对整体叶轮及类似零件的精密成形加工具有一定的工程实际意义。 |
| 英文摘要: |
| Integral impeller has a complicated structure and has strict precision requirement on processing. The blade is free-profiled and distorted to some degree, and the flow path is narrow. Hence, prone to overcutting, collision, interference and other problems, the processing is rather difficult. A CNC machining forming proposal was put forward for integral impeller based on engineering application. It focused study on the blade forming process simulation based on UG NX10.0 software CAD/CAM modules and verified the feasibility of the method. The CNC forming proposal could get a better form after verification by simulation. It has a great significance for the precision forming of integral impeller and similar parts. |
