Re: Undersize with flat endmill...

Cliff, the problem is that if I use a ball end mill I don't have sharp
inside corners. Everything winds up with a radius. And if you fake it
the math is not correct and the path violates the surface on the
outside radius. The only way that I know around this is to create two
trodes which is time consuming both in the CNC work and the EDM. On
occasion they have been simple enough to manually clean up some of
these trodes but that is also time consuming.

I don't think you can directly produce sharp inside corners with a flat
endmill either ....
Have you considered assembly? ( I see"two electrodes"<G>.)
Might consider a sharp wood chisel too I suppose ..
