I was cutting some T-slots today with a 3/8" cutter in some cold rolled.
It took quite a bit of time and I had some major problems with
chatter. That meant that I had to keep my feed extremely slow. I varried
the cutter speed all over the place and and couldn't find ant that made
thing better. I was wondering if my technique was bad. What is the
proper technique and speed for a T-slot cutter?
I went in first with an sharp hogging end mill and cut to almost full
depth. I then went in next with new T-slot cutter and cut the slots. I
noticed that taking the cutter right down the center line of the hogged
slot. Upon finishing, noticed that one side of the T was a little wider
than the other. What am I doing wrong?
