This function permits cutting a fixed pattern repeatedly, with a pattern
being displaced bit by bit. By this cutting cycle, it is possible to efficiently
cut work whose rough shape has already been made by a rough machining,
forging or casting method, etc.
The pattern commanded in the program should be as follows.

∆i : Distance and direction of relief in the X axis direction (Radius
designation).This designation is modal and is not changed until the other
value is designated. Also this value can be specified by the parameter No.
5135, and the parameter is changed by the program command.
∆k: Distance and direction of relief in the Z axis direction.
This designation is modal and is not changed until the other value is
designated. Also this value can be specified by the parameter No. 5136, and
the parameter is changed by the program command.
d: The number of division
This value is the same as the repetitive count for rough cutting. This
designation is modal and is not changed until the other value is designated.
Also, this value can be specified by the parameter No. 5137, and the
parameter is changed by the program command.
ns: Sequence number of the first block for the program of finishing shape.
nf: Sequence number of the last block for the program of finishing shape.
∆u: Distance and direction of finishing allowance in X direction
(diameter/radius designation)
∆w: Distance and direction of finishing allowance in Z direction
f,s,t Any F, S, and T function contained in the blocks between sequence
number "ns" and "nf" are ignored, and the F, S, and T functions in this G73
block are effective.
