Re: [CAD_CAM_EDM_DRO] Digest Number 828

I am new to this list and have found most of the discussions to be of great interest since one day I would like to have made a cnc type retrofit to my mill.
However, my current interest is in EDM which doesn't seem to be a topic at present,
has this area already been exhausted?

I am currently building the HSM Robert Langlois version of a spark erosion m/c and would dearly love to hear from anyone that has improved upon this design. In particular, in relation to the type of capacitors used (I'm using conventional electros but feel paper would be better if available) and also in relation to the
use of fast switching (using power MOSFETS) to improve performance and reduce the capacitance values required.

Any information would be greatly appreciated.
