Hello, I've got some questions on feedrates, plunge and spindle speeds. I'm very new at this, so I've been running tests way too slowly for my tastes.
For my first pieces, I'm using wood panels out of hard maple. They are 203mm x 203mm x 45mm. I've currently been testing with a feed rate of 90mm, and plunge of 30mm. It seems really slow, but I'm not experience enough to say for sure that it is.
Also, the bit I'm using is a flat, 2 flute carbide. The fluting is 25mm, and I've been mounting it so there is an additional 10mm exposed from the nut. Which brings me to my next question, how much of the bit do you put in the the collet? Mine probably doesn't go all the way to the back of it, it's leaving about 10 mm from the back. Is it better to just buy a longer bit?
Oh, the spindle speed is about 12000 rpm too.
