VER5.13 45
Move the electrode until it touches the machining
plane as figure (K); display value of z axis is zeroed
automatically.
6. Start machining;
X window displays the expectant = EDM.DEEP;
Y window displays the current machined depth;
Z window displays the current position of the electrode;
Message window displays “EDM RUN”;
7. When Z window displays the value = EDM.DEEP =
-20.000, the buzzer sounds and the message window
displays “BACKWARD”, and then the machining stops
and the electrode withdraw.
During withdrawing electrode :
Z window displays the current position of the electrode;
X window displays the preset value = EDM.DEEP +
EDM.COMP;
Y window displays the formerly preset depth;
If the electrode doesn’t exit in 25 seconds; the DRO will
machine another hole by repeating steps 5~7.
When the electrode withdraw beyond fireproof (EDM.
HOME), the DRO will machine another hole by repeating
steps 5~7.
Press
to quit EDM when machining completes.
Press
to quit EDM during machining.
Note: The LED for
flashes during machining if DEEP.COMP is enabled.

Example for Mode 7
The operate step and machined work-piece of MODE 7 is alike
as MODE 5. The difference is that DRO must detect edge while
entering EDM function in MODE 7.
Process work-piece as figure (f): Z axis direction is down. Parameters are as following:
EDM.DEEP 20.100 mm
EDM.HOME 5.000mm;
