Cycle Time and Accuracy
Improvements

A new adaptive control function avail-
able on the third generation EDAF Series
is the Adapti-Spark Function or AiSF.
AiSF continuously monitors and adjusts
the spark and jump settings based on
the stability of the machining process.
The automatic adjustment to the

buildup on the corners of rib electrodes.
This results in more uniform electrode
wear and higher part accuracy. The
jump setting is dynamically adjusted
