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')

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.
