Example for Mode 2
DRO must be connected with the edge detector sensor. Press
to enter EDM, Z axis is
zeroed automatically and machining begins when the electrode touches the machining plane. As soon
as process to the expected depth, the relay sends out a signal to withdraw the electrode and stop EDM
machining. When the electrode beyond fireproof height, move the machine table to next hole to
machine another hole without pressing
. Mode 2 can process multiple holes conveniently.
Characteristics for MODE 2:
The DRO connected with sensor which can detect edge and zero display value automatically.
The DRO needn’t exit EDM to machine next hole.
EDM.DEEP can’t be minus;
Z axis positive direction and machining direction is down;
The electrode waste is very small and negligible;
Process six holes in one work-piece as figure (f) Z axis direction is down.
Parameters are as following:
A. EDM.DEEP 20.1 mm
B. EDM.HOME 5mm;
Take the mode of detecting and zeroing Z axis automatically.
STEPS:
1. Set the following parameters in initial system settings:
①
EDM MODE is set 2;
②
RELY.MODE is set0;
③
DEEP.COMP is set 0, electrode compensation is disabled;
2. Enter the normal display state with the following setting:
①
Display unit is metric;
②
Shrinkage is not taken into consideration;
3. Set parameters;
○
1
EDM.DEEP 20.100mm
○
2
EDM.HOME 5mm
4. Press
, the DRO will display as the right.
5. By moving the electrode until it touched the machining
plane, the z axis will be zeroed automatically.
6. Start EDM
X window displays the expectant = EDM.DEEP;
Y window displays the current machined depth;
Z window displays the current position of the electrode,
