SECTION 11   PROGRAMMING FOR SIMULTANEOUS 4-AXIS CUTS (2S Model)

The net cutting time per piece is 68 seconds when the part is cut in 4-axis simultaneous cut mode.  It
is 131 seconds (= 68 + 63) if the part is cut in the conventional manner.  This means that
simultaneous 4-axis cut yields nearly a 48% saving on cutting time.
