8-18. Drilling Depth Setting (Only for drilling cycles)
For the drilling cycles called by G178, G179, G181, G182, G183, G184, and G189, the drill hole
depth may be specified by an R command (see below) from the position shifted to by I or K, instead
of specifying the end point of the drilling cycles.
When using an R command in a fixed cycle program, program a block of commands like that shown
below.

R : Drilling hole depth in drilling cycleIn a drilling cycle, the drill hole depth (distance) is specified
by an R command.
The R command in the X-axis direction must be specified as a diameter.
The use of an R command allows the drilling cycle to be programmed by reference to the hole
depth instead of the end point of the cycle.
