New type matching output function:
1. Function
This function is used especially for processing by use of discharging
processing machine. When the set target valve on Z axis of spark machine is
equal to the current value, the digital display case exports switching signals to
control the spark machine tool to stop the in depth processing.
Model SDS2E digital display case has its
direction setup in the Z axis as shown in Fig. 1.
Namely, the deeper the depth goes, the bigger
the coordinate value displayed on Z axis. The
depth goes further ever since the processing
is stared, and the displayed value on Z axis
increases gradually.
According the set direction on Z axis,
the processing directions are divided into
positive and negative. When the electrode
goes down and processing goes from upper to lower, the value displayed on
digital display meter increases, and the processing direction now is
“positive”. This direction is then set as normal setup.
When the electrode goes up and processing goes from lower to upper,
the displayed value on the digital display meter is reduced, and the
processing direction now is “negative”, namely, the “negative processing” as
shown is Fig. 1.
