Example
Stock removal cycle, transverse axis (G72)
With the G72 command, stock removal cycle and rough finishing cycle in which
finishing allowance is left on face can be specified. In comparison to the cycle cal-
led by G71, which carries out cutting by the movement in parallel to the Z--axis, the
G72 cycle carries out cutting by the movements parallel to the X--axis. Therefore,
the cycle called by G72 executes the same operation as with the cycle called by
G71 in a different direction.
