Fixed cycle suspension
The function G27X suspends the active fixed cycle. G27X is valid only in the block where programmed.
Example:
…
G881 Z-40 J5 E10
(activates the fixed cycle)
G0 X100
(executes fixed cycle)
G27X
G0 X200
(doesn’t execute fixed cycle)
G0 X150
(executes fixed cycle)
G880
(deactivates fixed cycle)
G0 X200
(doesn’t execute fixed cycle)
…
Return position of fixed cycles
The return position of fixed cycles is set with the parameter E.
Example:
N1 G0 Z10
N2 G881 Z-10 J3 E5
N3 G0 X50
N1 – Rapid positioning to Z10
N2 – Fixed cycle preparation
N3 – Drilling execution: at cycle end, the Z axis is positioned to the Z5 position.
Modification of recall parameters for fixed cycles
It is possible to modify the parameters of the activated fixed cycle through the corresponding function G881-G886.
Example:
…
G881 Z-40 J5 E10
(activates the fixed cycle)
G0 X100
(executes the first drilling)
G881 E20
(changes the final return position)
G0 X150
(executes the fixed cycle with the new return position)
G880
(deactivates fixed cycle)
…
Modification of fixed cycle and parameter settings
It is possible to modify the fixed cycle, while maintaining the parameters of previous cycle.
Example:
…
G881 Z-40 J5 E10 F1200
(activates the drilling fixed cycle)
N1 G0 X100
(executes the first positioning)
X150
(second positioning)
N2 X200
(third positioning)
G886 Z-35 F400
(activates the boring fixed cycle)
(NOTE! The J and E parameters remain those of the preceding cycle)
(repeats the positionings)
!GON1-N2!
G880
(deactivates fixed cycle)
…
Warning
: For a better understanding and a clearer programming, and to avoid not easily recognizable behaviors, it
is advisable to clear all calling parameters with the
G880
function, each time a fixed cycle is changed. In this way it
is necessary to program anew all values necessary for the cycle. Example:
