Tool Definition
Tool radius R
Sinking
erosion
For sinking erosion, the actual electrode radius
Re equals the tool radius R to be programmed
in TOOL DEE
The required cavity diameter D and the undersize
UM (equals minimum undersize UNS) given in
the erosion parameter table result in a radius:

D
cl
For contouring erosion with radius compensation
the actual electrode radius Re can be chosen
according to the required contour.
The tool radius R programmed
in TOOL DEF
results from the actual electrode radius Re and
the undersize UM (equals minimum undersize
UNS) given in the erosion parameter table.

Erosion with the
disk cycle
In the disk cycle the actual electrode radius Re
equals the tool radius R to be programmed
in
TOOL DEF.
Any actual electrode radius Re can be chosen,
provided that it is greater than the expansion
radius RAD to be programmed
in the disk cycle.
