I always thought there had to be a logical explanation for these things. After my own cat pulled a similar trick, I had to accept that sometimes we just don't know how they do it. It's one of those small mysteries.

Wow, that's a LOT of processing! My hair would just give up and fall out.

But that hat also protects the new growth from sunburn.

My old shop foreman always drilled into us to slow down for finish passes. I ran a job last month with some 7075 parts that were chattering like crazy, so I tried dropping the feed and it just made it worse. Pushed it up from 50 to 65 and the tool stopped bouncing off the wall. It totally flipped my thinking on how to handle thin material.

Sounds like the modern version of snake oil salesmen.
