Was the pocket large enough relative to the end mill so it would

Yes, Don. That would be intuitively obvious. I milled a 2.5" square
"pocket frame" .125" deep with a 3/8" bit, just to be sure.

Good enough! That was not clear from what I saw before.

G78 == Pocket Mill
G172 == Pocket Frame Mill

So far, the only thing I can see that is apparently different (don't have
any docs on the parameters, except from ONE programming example) is that
the "pocket frame" cycle appears to have a parameter for the radius of
the corners.

O.K. It may have another parameter for width of frame, and when
not set, it defaults to normal pocketing.

Enjoy,
DoN.
