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.
