6. Automation
Electrical discharge machining (EDM) developed rapidly from the 1980s onwards, thanks to two major advances:
improved performance, mainly thanks to generators and feed control systems;
extensive use of automation, with multi-axis numerical controls and rational management of electrode production and positioning.
6.1 Generator
The generator must be able to deliver discharges of short duration (a few microseconds to a few milliseconds), with currents of up to a few tens or hundreds of amperes, at a very high repetition rate.
No progress has been made on ripping machines. Some manufacturers use high-voltage discharge pre-priming...
