Hi all,
can someone verify a machine setup for me. I'm cutting cast iron on a bridgeport with BR2J head. Its an interrupted cut, probably 45 degrees of a circle 13" diameter. I'm using a 3" boring head with 3/4" brazed carbide tooling, side mounted.
I have set these figures:-
depth of cut=0.25mm
feed rate=0.15mm/rev (.006")
speed=90rpm (300fpm)
does that sound ok or too heavy in one way or another?
i'm only asking as its a long job and i have two to do.
results so far seem ok but i dont want to kill the tool or machine.
thanks in advance
