If you aren't familiar with what I've already put in the public domain,
you should
look at : http://ascc.artsci.wustl.edu/~jmelson/gcode.html which is my
page
of programs that write G-code. You answer a few questions, and these
little
c programs (supplied as source) write the g-code for boring circular
holes or
pockets, milling out a rectangular pocket or trepanning out a
rectangular hole,
drilling (and also peck-drilling) a circular array of holes (bolt
circle).
There is also a program for thread milling with a single-row thread
mill.
(These can do any thread pitch with one tool.)

I have a few more that I need to clean up and add to the list. I use
these
more than my Bobcad/CAM software, because I don't have to fight it to
get it to do things in a milling machine-oriented way. These programs
are
pretty well optimized for efficient movements of the tool. They pretty
much
all do climb milling profiles.

If someone wanted to recode them in Tk/Tcl for use with the TkEMC user
interface of EMC, I'd be glad to help explain any quirky bits of the
code.
