Greetings all;
It has occurred to me that holes could drilled by edm with a lot less
gcode to write if the hole was drilled by EDM using polar/rectangular
notation.
The OEM hole is a three lobe design that is about 5mm in diameter, in
steel around .3mm thick. borrowed from a seamstress's fabric cutter. So
this likely is going to need at least one change in the basic starting
diameter of the tool doing the erosion. But using polar/rectangular
notation strikes me as one way to make lcnc describe 10 or 15 copies of
the perfect circle by specifying the radius and say 3600 degrees, while
dropping or raising the tool to distribute the tools erosion so 95% of
the lose of metal is from the hole in the disc growing larger, all in
one actual gcode command line once the tool has been moved to the
radius, with the radius being the loops constraint. I have room in the
printed and painted to waterproof jig pan to use 7 or 8mm of z motion,
and intend to use the axle it spins on for the last half a mm of
expanding this hole.
So the data on using polar/rectangular type coding is in what section of
the docs (now around 1200 pages) so I can look this up as I compose this
g-gode?
Thanks a bunch.
Cheers, Gene Heskett, CET.
