Fanuc G90 turning cycle is used for simple turning however multiple passes are possible by specifying the X-axis location of additional passes.

Called with many names like – Fanuc G90 Outer Diameter/Internal Diameter Cutting Cycle or G90 Straight cutting cycle

Programming Format

G90 X... Z...

G90 U... W...

X – Diameter to be cut.
Z – End point in z-axis.
U – x-axis incremental distance to target.
W – z-axis incremental distance to target.
