10. A device for defining a pulsed electrochemical machining (pECM) tool, comprising:
a memory configured to store:
workpiece model data representative of a finished surface of a master workpiece; and
initial electrode model data representative of a working surface of an initial electrode; and
one or more processors configured to:
receive workpiece measurement data representative of a machined surface of a machined workpiece, wherein the machined workpiece has been machined by the working surface of the initial electrode, and wherein the workpiece measurement data comprises a first point cloud;
identify a set of dimensional differences between the workpiece measurement data and the workpiece model data, wherein the workpiece model data comprises a second point cloud, and wherein the set of dimensional differences comprises a plurality of vectors representing a distance between corresponding data points of the first point cloud and the second point cloud;
update, based on the set of dimensional differences, the initial electrode model data; and
output the updated electrode model data.
