then the machining stops and the electrode
withdraws.
The actual machined depth is 20mm when Z
window
displays
value
=

+
EDM.COMP = 20.1 because of electrode wear.
During electrode withdrawing, Z window displays
the current position of electrode, X window displays
the preset value (EDM.DEEP + EDM.COMP), Y
window displays the formerly preset depth;
The DRO will quit EDM and return normal display state
