SW4000 USER’S MANUAL
VER5.13 41
Message window displays “EDM RUN”;
7. When the Z window displays value = EDM.DEEP = 20.1,
the buzzer sounds and the message window displays
“BACK WARD”, and then the machining stops and the
electrode withdraw;
During the electrode withdrawing:
Z window displays the current position of the electrode;
X window displays value = EDM.DEEP + EDM.COMP;
Y window displays the formerly machined depth.
If the electrode doesn’t exit in 25 seconds, the DRO will
enter the steps to machine another hole by repeating steps
5-7.
If the electrode beyond the fireproof height (EDM
HOME), the DRO will enter the steps to process another
hole by repeating steps 5~7.
Press
to exit EDM when machining completes.
Press
to exit EDM during machining.
Note: The LED for
flashes during machining if DEEP.COMP is enabled.
5.2.4
Example for Mode 3
Compared with Mode 1 Mode 3 hasn’t the function of fireproof height. DRO can exit EDM only
when the electrode goes down again. The datum will not change because z axis is not zeroed again to
machine next hole. This mode is only used in case of the electrode waste is too small where waste to be
neglected.
Process the work-piece as figure (F) in 5.2.3, Z axis direction is down;
EDM.DEEP 20 .100mm
STEPS:
1. Set the following parameters in initial system settings;
EDM MODE is set 3;
RELY.MODE is set 0;
DEEP.COMP is set 0, depth compensation is disabled;
2. Return normal display state with the following setting;
Display unit is metric;
Shrinkage is not taken into consideration
3. Set parameters in EDM;
electrode begin
withdrawing
