3.24.2.5 Drilling Cycle, Counter Boring Cycle G82
Format：G98/G99 G82 X_ Y_ R_ Z_ P_ F_ L_ ；
Function: Cutting feed is performed to the bottom of the hole. Hole depth precision is added when
the dwell is performed, and then the tool is retracted from the bottom of the hole at rapid
traverse.
Explanation: For the command explanation of these canned cycles, see the Table 3-2
Cycle process:
(1) Positioning to the XY plane level at the rapid traverse;
(2) Down to the point R plane at the rapid traverse;
(3) Cutting feed to the bottom of a hole
(4) Dwell for P time if it is commanded.
(5) Returning to the initial point or point R plane according to G98 or G99 at the rapid traverse;
