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 pulsed electrochemical machining (pECM) system including a pECM assembly. The pECM assembly includes a tool body which defines a tool axis and includes an electrode which includes an electrically conductive material and defines working surface. The pECM system includes an electrolyte system configured to supply electrolyte to an interelectrode gap, and the electrolyte system includes a vacuum system. The tool body defines a working surface configured to face a workpiece, and the working surface defines a plurality of apertures configured to fluidically couple to an electrolyte system. The tool body includes a manifold block defining at least one electrolyte inlet and at least one electrolyte outlet, a baffle element, and the electrode. The tool body is configured to receive electrolyte from an electrolyte system at the electrolyte inlet in the manifold block and feed electrolyte through the baffle element to the working surface of the electrode.

Abstract: The disclosure describes a pulsed electrochemical machining (pECM) tool that includes a tool body defining a tool axis and including one or more electrodes. Each of the one or more electrodes includes an electrically conductive material and defines a working surface at a distal end of the tool axis configured to face a workpiece. An electrical conductivity of at least one electrode varies across the working surface of the respective electrode.

Abstract: In some examples, pulsed electrochemical machining (pECM) system, including an pECM tool comprising a tool body, the tool body comprising an electrode defining a working surface configured to oppose a workpiece during a pECM process; an electrolyte system configured to supply electrolyte to an interelectrode gap between the working surface of the electrode and a target surface of the workpiece; and a power supply configured to generate a pulsed direct current between the one or more electrodes of the pECM tool and the workpiece during the pECM process. The electrode includes an oxidation resistant layer defining at least a portion of the working surface, and a diamond-like carbon coating that defines another surface of the electrode.

Abstract: Techniques are described by which to enable uniform machined parts inspection processes. A device comprising a memory and a processor may be configured to perform the techniques. The memory may store a unified scan of a workholding piece with a machined part, where the unified scan defines a coordinate system for the workholding piece. The memory may also store a reference model of the machined part. The processor may align, based on the coordinate system for the workholding piece, the unified scan of the workholding piece with the machined part to the reference model, and perform, after aligning the unified scan to the reference model, a comparison of the unified scan to the reference model. The processor may output, based on the comparison, an indication of compliance or non-compliance with the tolerances for the machined part.
