As shown in the figure below, this cycle is the same as G71 except that
cutting is made by a operation parallel to X axis.

Signs of specified numbers
The following four cutting patterns are considered. All of these cutting
cycles are made parallel to X axis and the sign of ∆u and ∆w are as follows:

Removal in Facing
The tool path between A and A′ is specified in the block with sequence
number "ns" including G00 or G01, and in this block, a move command in the
X axis cannot be specified. The tool path between A′ and B must be steadily
increasing and decreasing pattern in both X and Z axes. Whether the cutting
along AA′ is G00 or G01 mode is determined by the command between A and
A′, as described in item 13.2.1.
