Martin, I looked at that recent sample, and I think you missed my original issue:  (BTW, thanks!)

These "enlargement' operations begin on _existing_ holes of various sizes, that must be enlarged to _other_ various sizes.  The amount of material to be cut out changes with every enlargement operation, so no single cutter path width will suffice.  It must be different for every hole.

If one were enlarging a 25mm hole to 35mm, the cutter path width would be 5mm.  But if one were enlarging a 25mm hole to 125mm, the width would be 50mm.

That's why I said it would be nice to have that figured for me, rather than having to do the math for every pocket or profile.

Your help was valued.  I got this working the way I needed.  'Just got to keep the calculator handy.

Try the same on this file, without cutting any 'air'.

Sounds like a pocket with an island might be the answer?  Sorry if somebody already mentioned it.  I only skimmed the first page of replies. 

Getting started on CNC?  In or passing through my area?
If I have the time I'll be glad to show you a little in my shop.
