We have a two vertical Jig Bore machines with a Fanuc 31i model A3 controls.

On one of the machines, when jogging with the handwheel, the axis position stays within the resolution that is selected, no matter how fast you spin the handwheel.

The other machine stays within the resolution up to a certain speed. Once you exceed a certain speed, the position gets outside the selected resolution.

So if I have .010 inch per click of the hand wheel selected I want the position to always move a division of .010

Wanting to see if anyone else has tackled this problem.

Thanks,
