German term or phrase: Formelektrode
Beim PEM-Verfahren wird, wie beim klassischen elektrochemischen Senken, das zu bearbeitende Werkstück anodisch (Pluspol) und die ***Formelektrode*** kathodisch (Minuspol) geschaltet. Ein Elektrolyt fließt zwischen ***Formelektrode*** und Werkstück, um den gepulsten Gleichstrom zwischen beiden Polen zu übertragen und die herausgelösten Metallbestandteile abzutransportieren.

Beim PEM schwingt jedoch die ***Formelektrode*** mit einer Frequenz von 10 bis 60 Hz in Z-Richtung. Dabei vergrößert und verkleinert sich der so genannte Reaktionsspalt periodisch.

tool


Explanation:
"A positively charged workpiece (the anode) takes the form of the negatively charged tool (the cathode) as the metal is dissolved. The result is a high quality, burr-free part."

http://rm.holdings/PEM/

In the PEM process, a cathode (tool) is advanced into an anode (workpiece). The metal removal current is pulsed while in close proximity (typically 10—20 µm gap), and then retracted.

agree  Annika Hogekamp: Maybe "tool-electrode" would be more precise. - See wikipedia article on "Electrical Discharge Machining" (EDM)

  -> thanks, Annika!

agree  Marcus Malabad: This is the answer. Simply looking up precision electrochemical machining (the context here) will reveal the answer

cutting/champfering electrode


Explanation:
https://www.moldmakermag.com/articles/graphite-cutting/
cutting electrodes for Ram EDM core and cavity details that can’t be hardmilled because of their size or reach

"Master" might be closer to what was written. Or electrode shaped into the form being cut.
https://en.m.wikipedia.org/wiki/Electrical_discharge_machini...
In sinker EDM, a graphite, copper tungsten, or pure copper electrode is machined into the desired (negative) shape and fed into the workpiece on the end of a vertical ram... For the creation of dies for producing jewelry and badges, or blanking and piercing (through use of a pancake die) by the coinage (stamping) process, the positive master may be made from sterling silver, since (with appropriate machine settings) the master is significantly eroded and is used only once.
