Okuma multus b300... Need to thread mill a 1 1/8 - 7 unc 2b internal using a sing prof thrd mill. Its .745 dia. I understand the method, start at bottom and thread out, but the programming got me a bit confused. I dont do much milling yet. Its only .6 deep. Any tips would be great!

You've been a bit sparce with the info.
So all I can do is post part of a prog I use.
Are you threading axially or radially?
My example is using the slant function but is basically programmed in the XY plane G17 (axially).
Hope it helps
