re:Automated "Manual CNC"

Brian,

The easiest way would be to use a program like Vector CAD/CAM, put in
the tool compensation around the "cuts" (like an offset) you want to
make, output a GCODE file, and then run your hardware by interpreting
that. A CAD package (see past threads, get one free) COULD output a
.DXF file (remember the offsets), which you COULD directly "interpret"
and drive motors with. You COULD also output HPGL (plot files), and
"interpret" them. Can you write BASIC or 'C' ? Modify stepster to do
"closed loop" drive for your motors and linear encoders.

To directly answer your question:
"Outline" your parts in the CAD program, export .DXF, convert to GCODE
or "interpret" the simple (?) man-readable .DXF file with your own
program to drive motors (closed loop).

Alan (hope this helps)
