Remachining paths can be testy at the best of times.
Your method is sound, but could be taken a little further.
select all the operations before this re-machining op. and run it thru verify.
create an STL file of the stock while still in verify.
take this file and use it in the remachining operation
- use STL, ( not previous operation or tool dia. )
What you end up with is the same sort of paths as before but any paths that cut nothing are deleted.
This method is good for other strategies that can have a CAD button on the drive surfaces dialog ( ie surfacing and HSM )
