A fixture holds and positions the work but does not guide the tool. Whereas a jig holds, locates and as well as guides the tool. The fixtures are heavier in construction and are bolted rigidly on the machine table. Whereas the jigs are made lighter for quicker handling, and clamping with the table is often unnecessary.

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.

The difference between 2D milling and 3D milling lies largely in the number of machine axes that can be commanded on each line of NC code. Typically, with 2D milling, only the X and Y axes will be used on any given movement at the machine. In contrast, a simultaneous X, Y and Zaxis movement can be used when 3D milling.
