Drilling Cycles and Drilling Patterns
2.1 Drilling cycles
If the values for the reference plane and the
retraction plane are identical, a relative depth must
not be programmed. The error message
61101 "Reference plane incorrectly defined" is
output and the cycle is not executed. This error
message is also output if the retraction plane lies
behind the reference plane, i.e. the distance to the
final drilling depth is smaller.
Programming example
Drilling_centering
You can use this program to make three holes using
the drilling cycle CYCLE81, whereby this cycle is
called with different parameter settings. The drilling
axis is always the Z axis.
