I'm attempting to set up a pocket clearing operation where I helix ramp into the material, then use a high speed clearing strategy (large DOC, small WOC, not slotting using the full cutter width). The default cutting parameters look reasonable as shown in the screenshot:

I go into Circle/Ramp and input the helix parameters and ramp angle and check Ramp Plunging since I am only using the ramp to plunge per the article you wrote.

When I click Apply, it overwrites the DOC and WOC with the pitch and width from the Circle/Ramp dialog.

If I return to Circle/Ramp, the selection has moved to Ramp Milling. I can not get it to stay on Ramp Plunging and it has reduced my feeds. 

Is there some parameter I set that is forcing it to allow only Ramp Milling?

Or is the correct usage to treat these as two completely separate calculations where the helix is ramp milling as shown above, and for the main pocket clearing I clear this and treat it like normal cut?

What I expected to happen was for the main screen DOC and WOC to not be affected by enabling Circle/Ramp and only the plunge feed to have been changed since I was using Ramp Plunging but it seems to ignore the selection and treat as Ramp Milling.
