Example 2: Mill
 Mount the fourth axis as described above. Mount a part 3” in
diameter and 5” long on the face of the rotary table. The part has a
0.25” radius turned on the end. Shortest Distance is set to off.
 Assume that a series of six 0.25” wide grooves must be milled 60°
apart, 0.25” deep at the start, tapering up to 0.125” deep and
rotating 15° at the far end. The groove must follow the end contour
of the part (radius). Set X0 at the right end, Y0 at the cylinder center
line, U0 at a pre-milled keyway on the cylinder. Set the tool offset so
that the center line of the 0.25” ball-end mill is at the center line of
the 3” diameter part (with Y axis at 0).
