Example for Mode 6
The operate step and machined work-piece of MODE 6 is the same as MODE 2. The difference
between them is Z axis positive direction: in MODE 2, the Z axis’ positive direction is down,
EDM.DEEP is plus when machining down; in MODE 6, the z axis’ positive direction is up,
EDM.DEEP is minus when machining down.
The DRO must be connected with the sensor that can detect edge
and zero Z axis’ display value automatically. Pressing
to enter
EDM function, the display value of Z axis is zeroed and machining
began when the electrode touches the machining plane. When the
display value of Z axis equals to or larger than the expected depth, the
relay sends out a signal to withdrawing the electrode; if the electrode
beyond the fireproof height, move the machine table to next hole to machining another hole without
pressing
. Mode 6 can process multiple holes quickly.
Running conditions for MODE 6:
The DRO must be connected with the sensor of an electric edge detector if you want to use
automatically detect edge function;
The DRO doesn’t exit EDM after one hole is machined;
EDM.DEEP can’t be plus;
Z axis direction is up and machining direction is down;
The electrode wear is very small and can be neglected;
Process six holes in one work-piece as figure (J), Z axis direction is up. Parameters are as following:
EDM.DEEP 20 mm
EDM.HOME 5mm;
STEPS:
1. Set the following parameters in initial system settings;
EDM MODE is set 6;
RELY.MODE is set 0;
DEEP.COMP is set 0: depth compensation is disabled;
2. Return normal display state with the following setting;
The display unit is metric;
Shrinkage is not taken into consideration.
3. Set the parameters in EDM function:
EDM.DEEP 20.000mm
EDM.COMP 5mm
4. Press
, enter the EDM function.
5. The DRO displays as the right.
