Hi, 

Every think is about whisper cuts with the rest machining. It is intentionally to leave .181 for second operation. I calculated it from stock to leave and tolerances from previous operation. Without it I get a lot of whisper cuts. It means that to eliminate whisper cuts you need increase stock to leave with every next rest machining. And than with more and more rest machining your stock to leave is getting bigger and bigger. Also what I have noticed is that with bullnose and ball endmils you need leave more stock to leave than with flat endmills. Is there a way around to eliminate this whisper cuts and keep the same stock to leave in next rest machining? I am using a lot high feed cutters to remove stock and would like to come with rest for smaller tool, and I have problem how to set it up. In my test I included three different tools, I would like to get it working fine.
