1.1.5 Modifying the parameters of a canned cycle.
Canned cycles (·M· model)
Inside the influence zone of a canned cycle, it is possible to modify one or several parameters
of the cycle without having to redefine it. After modifying the parameters, the CNC keeps the
canned cycle active and carries out the machining operations with the updated parameters.
The parameters of the cycle are modified with the V.C.A variable for parameter ·A", V.C.B
for parameter ·B· and so on. The values of these variables are defined in absolute coordinates
with respect to part zero.
Here are two programming examples where the work plane is XY (X as abscissa axis and
Y as ordinate axis) and Z as longitudinal axis.
