数控电解加工整体叶轮的关键技术

Key Techniques of Numerically Controlled Electrochemical Machining of Integrated Impellers

以平行直纹型面的数控展成电解加工为例,对数控电解加工整体叶轮的主要关键技术,包括成形规律、展成运动、数控编程、阴极设计制造、机床及多轴联动数控系统、典型叶轮加工工艺逐一进行了介绍。

Taking the numerically controlled-electrochemical contour evolution machining (NC-ECCEM) of a parallel straight generatrix surface as an example, the key techniques of NC-ECM of an impeller are introduced, including the shaping law,the evolution movement,the NC programming,the design and manufacture of tool-cathode,the machine tool and the relative NC system,the technology for manufacturing some typical integrated impellers.
