work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, its neccessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with t-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
