ABSTRACT:
A CRT or other screen display represents a preliminary trace during an EDM or other electrical machining operation upon which can be superimposed a trace representing the action position of the tool vis-a-vis the workpiece or which may be optically scanned so that deviations of the actual machining path from the visible trace can be detected and used for shutdown of the machine.
