Programming Note: G82 is similar to G81 except that you have the option to program a dwell (P)

G82 Spot drilling example
G83 Normal Peck Drilling Canned Cycle (Group 09)
F Feedrate in inches (or mm) per minute
I Size of first cutting depth
J Amount to reduce cutting depth each pass
K Minimum depth of cut
L Number of holes if G91 (Incremental Mode) is used
P Pause at end of last peck, in seconds (Dwell)
Q Cut depth, always incremental
R Position of the R plane (position above the part)
X X-axis location of hole
Y Y-axis location of hole
Z Position of the Z-axis at the bottom of hole
If I, J, and K are specified, the first pass will cut in by the amount of I, each succeeding cut will be reduced by
amount J, and the minimum cutting depth is K. Do not use a Q value when programming with I,J,K.
If P is specified, the tool will pause at the bottom of the hole for that amount of time. The following example will
peck several times and dwell for 1.5 seconds:
G83 Z-0.62 F15. R0.1 Q0.175 P1.5.
The same dwell time will apply to all subsequent blocks that do not specify a dwell time.
