铰链类零件是航天型号产品中的关键核心部件，单向走丝电火花线切割是其理想的加工方法。针对加工过程中存在的装夹精度难以保证、零件易变形、加工效率不高的问题，从柔性装夹、多次切割路径规划及变厚度切割优化等方面出发，提出了适合航天铰链类零件的单向走丝电火花线切割加工工艺方案，并通过实际产品生产验证了该工艺方案的有效性。

Unidirectional travelling wire electrical-discharge machining is an effective approach for processing gemel components which play a key role in the aerospace product. Aiming at the problem such as the improper accuracy of clamping ,the part distortion and the low processing efficiency ,a processing scheme for gemel compoents ,which based on the flexible fixture ,multi-cutting processing and variable-thickness cutting processing ,is proposed. The validity of this method was proved with an processing experiment.
