Re: What's a good speed for a rotary table?..More info - feed rate

From the cutter side of things, figure out what your fastest cutting
speed is in a straight line on your material. if you cut 25ipm and
that works great, then figure out what speed you need to get the
material past the cutter at the same inches per minute on the rotary.

for metal, I figure how deep a cut per flute for feed rate. taking
0.001" per flute is 500 revolutions per inch for a 2 flute cutter.
cutter speed dictates ipm table feed rate.

it would seem you have the choice to vary the speed of the table, or
to vary the speed of the router and get the same depth of cut per
flute.

and, it would seem that if you already have some good numbers on your
materials, you can calculate the table speed pretty easily.
