Example 1: Drill
Mount the fourth axis as described above. Mount a part 6” wide and
8” long on the face of the rotary table. Shortest Distance is set to
off.
Drill (10) ten 0.375” holes 36° apart, 1” deep, 0.75” in from the end
of the cylinder. Then, starting at X-2 U0, drill a spiral series of holes
36° and X-0.500” apart each. Set X0 at the right end, Y0 at the
cylinder's center line, U0 at a pre-milled keyway on the cylinder.
Measure tool offsets from the top of the cylinder, with Y-axis at 0.
