wms thanks.
I've been told there's no such thing. Too small. And after
thinking on it some more, I'm not going to gain as much as I thought (if anything) anyways. First of all I need to correct myself above. The sf will be the same. It's the speeds and feeds that will increase due to smaller cutter dia. And conversly I'll be taking 1/2
doc. and less chip load. So... I'll be moving not quite, twice as fast, but taking twice as many cuts.
IF that is true, THEN I may not even be able to loose the semi-finish tool, because I would have still roughed with the bigger tool agressively and semi-finished with the smaller ceramic.
It was a win, loose, loose deal.
I'm gonna try somthing else.
