Fanuc G85 Boring Cycle is also called Fanuc G85 Reaming Cycle.
As Fanuc G85 boring cycle can be used for Reaming operation.
X Y – Hole position
Z – Boring depth (Absolute).
R – Tool starting position above the hole.
F – Cutting feed rate
K – Number of repeats (if required)
Fanuc G85 Boring Cycle Operation
1 – After positioning along X and Y axis, rapid traverse is performed to point R.
2 – Boring/Reaming is performed from point R to end-depth-point Z with specified feed F.
3 – After completing depth Z with feed F, Tool returns with the same feed F.
Return plane is dependant on G98, G99 G-codes.
If G98 is specified with G85 boring cycle the tool returns to Initial-level.
If G99 is specified then tool will return to R level.
