G80
G76 F____ P____ R____ Z____ G98/G99
The G76 command specifies the fine bore drilling cycle. At each axis position, this cycle will
execute the following.
1 Rapids to point R
3 Dwells by P seconds at the bottom
4 Orients the spindle
5 Moves in XY (distance and direction specified by CTRL parameters 'Bore Relief
Angle' and 'Bore Relief Distance')
6 Rapids out of hole to point R/initial point, specified by G98/G99
7 Moves back to original XY position
Custom drill cycle (G77)
This is a custom drill cycle. It can be used to perform a user-defined cycle. The cycle must be
defined by a custom G code, G79.
Example:
G77 R.1 Z-2
X1 Y2 (does what is in G79)
Y-2 (does what is in G79)
.
.
X3 (does what is in G79)
Custom drill cycle can be used in bolt hole cycles, grid of holes, or spaced holes. If G79 is not a
custom code the error 549, unrecognized G code, will occur.
