Systems and methods for forming features within composite component using tubular electrode

A system for forming a feature within a composite component includes a tubular electrode extending in a longitudinal direction from a proximal end to a distal end. Further, the distal end is configured to be positioned relative to a machining surface of the composite component such that a spark gap is defined between the distal end and the machining surface. Further, the tubular electrode also extends in a radial direction between an inner surface and an outer surface, the inner surface defining a central channel configured to supply a dielectric fluid to the machining surface. The outer surface of the tubular electrode includes at least one channel or non-circular cross-sectional shape defined therein. 一种用于在复合部件内形成特征的系统包括沿纵向方向从近端延伸到远端的管状电极。进而，远端被构造成相对于复合部件的加工表面定位，使得在远端和加工表面之间限定火花间隙。此外，管状电极还在内表面和外表面之间沿径向方向延伸，内表面限定中心通道，中心通道构造成向所述加工表面供应介电流体。管状电极的外表面包括至少一个限定在其中的通道或非圆形截面形状。
