I had exactly the same problem with work slipping off angle plates in the vice, so I made a matching pair of 'vee plates' to use on the mill vice which gets over the slippingoff problem quite neatly. They work well on the surface grinder too. The plates have dowelled and screwed guides which can be changed over for either 45deg or 15deg angles.

On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.
