Thanks, Chris!   I agree with Sven, you've made G41/G42 perfectly clear.

I've spent the last several hours banging my head against my NEXT challenge,
one that I'm sure that many of you have been through. I want to use a .25"
endmill to cut a hole 0.505" in diameter. My (fruitless) approach so far has
been as follows. (Sorry for the G-English)

a) start at x0y0,
b) G42 to get tool comp
c) G1 out to a point on the .505" circle.
d) G02 in a circle, ramping down .1" in Z
e) G02 in a circle, ramping down to .2" in Z

So far I can't even write code (using expressions and named parameters) that
EMC will accept. I'm clearly in that amazing space where "experience" would
indicate a viable clever way to proceed. However, I am not yet experienced,
and today I certainly not clever enough? Can who is both of these point me
in a useful direction? (Ultimately I want to mill a number of these into a
single blank.)

Hoping to wise up sooner or later,
- Marty
