setting;
Display unit is metric;

3. Set the following parameters in EDM function;
EDM.DEEP -20mm
EDM.HOME 10mm
Height of withdrawing is defined as the
figure (H) DRO will exit EDM if electrode is
below EDM HOME.
4. Move the electrode until it touches the machining plane
as figure (I).
Press
to zeroing Z axis;
5. Start EDM.
Press
, then
X window displays the expectant =
EDM. DEEP + EDM.COMP;
Y window displays the current machined depth;
Z window displays the current position of electrode
Message window displays “EDM RUN”;
6. When the Z window displays the value = EDM.DEEP =
-20.000, the buzzer sounds and the message window
display “BACKWARD”. Then the machining stops and
the electrode withdraw.
During withdrawing electrode:
Z window displays the current position of electrode;
X window displays the preset EDM.DEEP;
Y window displays the former machined depth;
The DRO will quit EDM and return normal display state
automatically if the electrode doesn’t exit in 25 seconds.
The DRO will quit EDM function and return normal
display state when the electrode withdraws exceeds the
height of the withdrawing.
Press
to quit during the machining;
Note: Mode 5 and mode 4 is same if depth is minus. The step of mode 5 is same with mode 2.
