Counterbore Drill Cycle
 Counterbore drill cycle generally used for counterboring. It feeds
from the R-plane to Z depth, dwells for specified time, then rapids
to the return point.
 G-code format: G82
Peck Drill Cycle
 The peck drilling cycle is generally used for peck drilling relatively
shallow holes. It feeds from the R-plane to the first peck depth
(calculated so that all pecks are equal and do not exceed the
maximum peck distance programmed in I word). Then rapid retracts
to R-plane (to clear chip), rapids down to previous depth less .02",
and continues this loop until it reaches the final hole depth. It then
rapid retracts to the P dimension.
 G-code format: G83
