I mean the force of the cutter should be pushing against the work spindle. What you are refering to is climb cutting or conventional cut. So climb cut would be feeding away from the work spindle. Conventional would be toward it. Most of the force perpendiculat to the spindle so depending on the rigitity of the part you might want to feed toward the spindle.
I just did a worm job in a Mikron universal and the feed was .196 per revolution. I had a side cutter made with 15 gashes to minimize the chip load.
