depending on the year of the control it could be a two line read of a one, also i think one the new controls you can use either you have to change a pram.

Say your part is 1.5 od and your using a .125 groove and you want to groove 1" past Z0

G0G54T101
G50S2000
G96S600M3
X1.6Z-1.125M8(X.100 over the part Z is groove location)
G75R.025(R is how much tool will retract after each cut)
G75X.875Q200F.006(X is the diam. of groove Q is amount per cut)
G0X1.6
Z3.M9
M1

So it will take .02 per cut till reaching .875 will retract .025 to break chips
hope this helps

G00T0900
G96S250M3
G0X5.45Z1.T909M8
Z-.325 (start position for grooving)
G75F.005X4.1Z-1.94I250K1000 (x value is final dia. z value is final z wall. I value is amount of peck. k value is step over amount in z.)
I hope this helps this is for fanuc 11t)

On my machine the retract amount is set by a parmeter.

Better to replace R0 by R0.1 in the first line.
Do not use R in the second line unless there is room for lateral retraction.
