Could anybody explain FANUC G75 canned grooving cycle with example.
Thanks
Could anybody explain FANUC G75 canned grooving cycle with example.
Thanks
The attached page from my book should help.
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
individual who perceives a solution and is willing to take command. Very often, that individual is crazy.
Hursty,
jackson,
Thanks for the solution. I will try and let you guys know about the result.
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.
Thank you all. MY cnc is Oi Mate-TC.
I tried with above all got error but jackson format works. May be the Jackson fromat is compatible to my cnc.
G75 R0.
G75X43.5Z-37.95Q2600P500R0.5F0.1
G0Z2.
and it works.
thank you all . You all make me try and now i know something about it.
