Drilling Cycles
Chapter 26
26-8
Drilling cycles G83.1, G84.1, G86.1 and G81-G89 are modal, which
means they remain active until you program a G-code that cancels the
drilling cycle. Certain drilling cycles can, therefore, be repeated at
different positions without having to re-program all the parameters
associated with a given operation.
Similarly, any parameters specified in the block calling the drilling cycle
remain active until the cycle is cancelled, or until they are re-programmed
in a following block. L-words do not remain active and, instead, designate
the number of times the drilling cycle is repeated.
G00-G03, G33, G34 or G80 cancel drilling cycle mode.
Important: Start the tool rotating with appropriate programming before
the control executes a drilling cycle block.
CAUTION: On systems with more than one spindle, the
controlling spindle code determines which spindle (and its
related spindle modal M-codes) is active during drilling cycles.
All references to spindle activities (orient, reversal, etc.)
described in this chapter apply only to the controlling spindle.
See chapter 17.
The format for the G80 cancel or end fixed cycles is:
G80;
Programming a G80 cancels the currently active drilling cycle mode. G00,
G01, G02, G03, G33 or G34 also cancel any active drilling cycle.
If drilling cycles are canceled with a G80, program execution returns to the
mode which was in effect when the cycles were last turned on, for
example, G00 - G03 or G33, G34.
