为了改善现有仿生机器鱼外部结构存在的诸多问题，提出利用3D 打印技术、线切割技术、数控加工技术制作仿生机器鱼头部和内部机械结构件的应用方法。通过CAD制作图纸，选用熔融沉积成型(fused deposition modeling，FDM)技术的三维打印成型设备进行外壳制作，并利用雕铣机与线切割技术进行配合件加工。在环氧树脂和树脂清漆涂覆、精打磨再上胶的处理后，配合橡胶鱼尾能完成整个仿生机器鱼的测试。应用结果表明：3D打印以及相关机械加工技术可缩减原型制作时间、加快测试与迭代速度，对仿生机器鱼的加工与应用有较高的实用价值。%In order to improve the shortcomings of current robot fish external structure, put forward method that using three-dimensional printing technology, wiring cutting technology, NC machining technology to manufacture robot fish head and internal mechanical component. Based on CAD drawing, use three-dimensional printing equipment of (fused deposition modeling) FDM to manufacture shell, and adopt carves-milling machine and wire cutting technology to carry out cooperating parts machining. After coating epoxy resin and copal varnish, fine polishing and sizing, use rubber tail to realize bionics robot fish testing. The application results show that the three-dimensional printing and related mechanical machining technology can reduce prototype manufacture time, accelerate test and iteration speed, which have a high practical value to bionics robot fish machining and application.
