Abstract: The disclosure describes a method for defining an electrode of a pulsed electrochemical machining (pECM) tool that is performed by one or more processors. The method includes receiving workpiece measurement data representative of a machined surface of a machined workpiece. The machined workpiece has been machined by a working surface of an initial electrode. The method includes identifying a set of dimensional differences between the workpiece measurement data and workpiece model data representative of a finished surface of a master workpiece. The method includes updating, based on the set of dimensional differences, initial electrode model data representative of the working surface of the initial electrode and outputting the updated electrode model data.

Abstract: A fixture may include a plurality of alloy pressure pads shaped to contact a component to be brazed or diffusion bonded, a plurality of springs, and at least one alloy support. In some examples, each spring of the plurality of springs is shaped to have a substantially constant stress throughout the spring. The plurality of springs may be between and contacting the at least one alloy support and the plurality of alloy pressure pads to exert spring forces on the plurality of alloy pressure pads. In some examples, the plurality of springs include a plurality of silicon nitride springs.
