The value of this integrated programming with machine simulation upfront reduces the number of NC Code validation iterations with the final buy off simulation/verification system such as Vericut.  Below video shows the 3DEXP version. You can also do this with V5 programming as well. See youtube link further below.

Here is the youtube  link for V5.  https://www.youtube.com/watch? v=9ftg6oCKKz8&t=8s
