Contact base for grounding ceramic elements during electrical discharge machining

Methods of electrical discharge machining (EDM) ceramic components are provided. In one aspect, a method includes electrical discharge machining a ceramic component, such as a ceramic matrix composite (CMC) component. The ceramic component is electrical discharge machined while the contact substrate is positioned such that the conductive compliance and pressurized contact of the contact substrate engage the ceramic component and such that the conductive member of the contact substrate is conductive with the ground structure. 提供了放电加工(EDM)陶瓷部件的方法。在一个方面，一种方法包括放电加工陶瓷部件，例如陶瓷基体复合材料(CMC)部件。陶瓷部件被放电加工，同时接触基体被定位成使得接触基体的导电顺应性和加压接触接合陶瓷部件并且使得接触基体的导电构件与接地结构导电。
