R Plane
I, J, K, and Q are always positive numbers.
There are two methods to program a G73; first using the I, J, K addresses and the second using the K and Q
addresses.
If I, J, and K are specified, The first pass will cut in by the value I, each succeeding cut will be reduced by the value
of J, and the minimum cutting depth is K. If P is specified, the tool will pause at the bottom of the hole for that
amount of time.
If K and Q are both specified, a different operating mode is selected for this canned cycle. In this mode, the tool is
returned to the R plane after the number of passes totals up to the K amount.
