基于UG的半开式叶轮的数控加工

The NC machining of semi-opened impeller based on UG

半开式叶轮属于复杂曲面零件,在离心泵中被广泛应用。对某一半开式叶轮进行了结构参数计算和叶轮绘型,然后采用UG软件对其进行了三维精确建模,并分析了该叶轮的数控加工工艺,进而在UG软件里对该叶轮进行了数控加工刀具路径的编制和切削仿真,最后将生成的数控程序传入加工中心进行了实际加工。该方法加工出的半开式叶轮尺寸精确、表面质量好。

Semi-opened impeller belong to the complicated curved surface parts, is widely used in centrifugal pump. It carries out the structure parameter calculation and drawing of a semi-opened impeller, then it creates the accurate 3 D model by UG software, and analyzes the numerical control machining process of the impeller. Then it carries on programming and simulation of numerical control （NC） machining tool path for the impeller in UG software. Finally, the generated numerical control program is passed to the machining center for actual processing. In this way, a size accuracy and good surface quality semi-opened impeller is machined.
