\par \cf0\b0\fs20
\par \pard A G83 (Deep Hole Peck Drilling) command is written in the following format:
\par (G9\f1\'d8 or G91) (G98 or G99) G83 X.... Y.... Z.... Q.... R.... F.... ;
\par \f0
\par G.... is defined as the canned cycle.
\par X.... Y.... is defined as the hole position, in absolute or incremental value.
\par Z.... is defined as the distance from the R point to the bottom of the hole in incremental mode, or the position of the hole bottom in absolute mode.
\par R.... is defined as the distance from the initial level to the R point level in incremental mode, or the position of the Z datum in relation to the R point level in absolute mode.
\par P.... is defined as the dwell time to be performed at the bottom of the hole (see the G\f1\'d84 code for more details).
\par
\par Q.... is defined as the cut-in distance value or shift value (Note - this is always specified as an incremental value).
\par K.... is defined as the number of repeats, for a series of holes. When not specified, K=1.
\par F.... is defined as the feedrate for machining.
\par \f0
\par Sequence of moves:
\par Op 1) Rapid position to X, Y and Z (the initial level).
\par Op 2) Rapid traverse to R point level.
\par Op 3) Feed in to the value of Q.
\par Op 4) Rapid traverse out to R point. Rapid traverse back to within 1mm of depth of Q cut. Operation moves 2 and 4 are repeated until Z depth is reached.
\par
\par Op 5) Rapid traverse to Initial level (G98) or R point level (G99).
\par
\par K.... is defined as the number of repeats, for a series of holes. When not specified, K=1.\fs16
