Re: [CAD_CAM_EDM_DRO] Inverse of G-code

Thanks to all for suggestions. For those interested in such things the one
by Carlos seems the best for this project -- use only one mold/die and a
urethane pressure pad.

Alan's suggestion of going back to the CAD package and doing the tool paths
there is probably the one I will use if the urethane pressure pad does not
work out.

The WORST POSSIBLE solution is to hand code it!! The little example given
below took over 30 minutes!! (So I am a code wimp! ;-) ) and the
design/mold I am working with is much more complicated!

For those curious here is a sample that I did to get the feel for the job.
The first G-code cuts the positive mold. The second cuts the negative
negative mold.

{program1 start}
;---------------------------------------
G00 Z.1
G00 X.5 Y1
G00 Z-.05
G01 Y.5
G02 X1 Y.5 R.25

G03 X.5 Y.375 R.25
G01 X.375
G01 Y1
G00 Z.1
G00 X0 Y0
M02

And now the other one while maintaining a .125" clearance around the
previous design:

Thanks again for all the help/suggestions.
