The programming of FGREF () is useful when machining with active multi-axis
transformation (e.g. TRAORI). In this case, in CUST_832.SPF, variable _FGREF is pre-
assigned a value of 10 mm. This value can also be modified. In CYCLE832.SPF, the value
of variable _FGREF is written to the rotary axes involved in the machining, which are
declared as orientation axis of a 5-axis transformation, using the FGREF(rotary axis)
command. When G70/G700 is active, the value from _FGREF is converted into inches
before writing to the command FGREF.
Take into account more than three rotary axes (orientation axes) in CYCLE832
In CYCLE832, a maximum of three rotary axes of the orientation transformation (TRAORI)
are taken into account for FGREF. If more than three rotary axes are declared per channel
for the orientation transformation, you can write the value to FGREF using the following
syntax in the CUST_832:
FGREF[AA]=$AA_FGREF[C]
C = rotary axis 1 (axis is taken into account by CYCLE832)
AA = rotary axis 4
In the manufacturer cycle CUST_832.SPF, parameter _MOTOL is available for the
evaluation of the "Multi-axis programming yes/no".
_MOTOL=0
_MOTOL=1
530
For deselection _OFF CYCLE832
For finishing _FINISH and _ORI_FINISH
For semi-finishing _SEMIFIN and _ORI_SEMIFIN
For roughing _ROUGH and _ORI_ROUGH
