Solution for Chatter

​This was my favorite line from the move The Social Network. I like to paraphrase it by saying:

"If you had the solution for chatter, you would have solved chatter"

...and that company/product would have 100% marketshare, but sorry  it doesn't work like that (and no one has 100%). You can't eliminate chatter, no product or process can. You can only avoid it. To avoid it you have to know where it is. By measuring the system's  (tool, toolholder, spindle) dynamics with a tap-test or RCSA you can determine the speeds and cutting depths that will avoid chatter and those that won't.
