Method of monitoring electrochemical machining process and tool assembly therefor
An electrochemical machining process is monitored by embedding an ultrasonic sensor in an electrochemical machining tool to provide a tool assembly, placing the tool assembly in a spatial relationship with a workpiece, disposing an electrolytic fluid at least in a gap between the tool and the workpiece, connecting the tool and the workpiece to an electrical power source, generating an acoustic wave from the ultrasonic sensor to propagate through the electrolytic fluid to the workpiece and reflect back from the workpiece, and, based on the propagation and reception of the acoustic wave, calculating measurement of at least the size of the gap or the thickness of the workpiece.
