Abstract: A method includes applying a force to elastically deform at least a portion of a superalloy turbine blade from a relaxed, initial position to an elastically deformed position. The at least a portion of the superalloy turbine blade has a curvature in the elastically deformed position not present in the relaxed, initial position. A hole is drilled generally span-wise through the at least a portion of the superalloy turbine blade in the elastically deformed position, and when the force is released, the superalloy turbine blade returns to the relaxed, initial position and the hole takes on a hole curvature within the at least a portion of the superalloy turbine blade.

Abstract: A fixture for drilling a hole in a superalloy turbine blade includes a mount to selectively hold a root of the superalloy turbine blade with the superalloy turbine blade extending from the mount. The fixture may also include an actuator to apply a force to elastically deform at least a portion of the superalloy turbine blade when held by the mount from a relaxed, initial position to an elastically deformed position, the at least a portion of the superalloy turbine blade having a curvature in the elastically deformed position not present in the relaxed, initial position. The fixture may also include a drill guide configured to guide a drilling element into the superalloy turbine blade in the elastically deformed position.

Abstract: Shape-tube electrochemical machining (STEM) systems, and methods of forming curved holes in components using STEM systems are disclosed. The systems may include a slider element, and an electrode coupled to the slider element. The electrode may include a linear body section, and a tip section. The tip section may be angled at a non-linear angle relative to the linear body section. The systems may also include a guide block slidably engaging the electrode. The guide block may include at least one aperture formed between a first and second section. The aperture(s) may receive the electrode. Additionally, the systems may include an electrode positioning block coupled to the linear body section of the electrode. The electrode positioning block may position the tip section of the electrode at a desired orientation relative to a component receiving the tip section to form a curved hole in the component.
