This is very nice feature and I have been using it ever since it came out. I even wrote a small vb-macro for it which turn the settings on and then replay the toolpath. And I use it very often while programming the part and rely on its accuracy. But I found a small glitch today as I was preparing the NCSetup assembly files for the next op, I saw a whole chunk was missing from pocket floor. So watch out. Sorry I can not send these files to DS because of ITAR.
I used old technique by replaying the tool-path on the extracted surface and looked it from the opposite side of tool-axis if I see the cutter showing up then it for sure is gouging. It was ramping approach in MAFC.
The only toolpath is robust for checking and modifying such App/Ret moves is ProfileContouring MO. DS team might want to look into its algorithms and enhance all other MOs based upon it.
