Please help.
Is there any rule to apply when programming Tool Nose Radius Compensation on Turning Centers to avoid alarms in the beginning and when turning compensation off.
Thank you in advance.

... And be sure your linear move is larger than the R value in your offset.
Thank you guys -
Nice and Simple.

We did run the program for 2 weeks,it was fine.But then the control started to comp. in two axis y&z, so we crashed the Machine,So called Fanuc support,they told as to wipe out the control(s-ram*****)We did that, it did fixed problem with z axis,but it still comp.x&y(did not do it before) we did try to add g40 in line n100 and it seemed like it took care of it,but not for long(for 3parts)The only thing fanuc guys told me(your prog. is wrong).Control we using is fanuc io-mc on Amera-Seiki machine.we have 3 machines same brand, same control hte other two doing ok. Any help would be great. Thanks

If this really is the beginning of your program, you never specify metric or inch (G21 or G20). (.735 mm is a whole lot less than .735 inches) Whatever is left over from the previous program it will still be stored.
Another thing noticed, what's that T2 hanging out on N100? It won't do anything without M06, but just curious if it was supposed to be used.
And another note, you need a G40 before an M30 or you'll get an error. Not sure if any of that helped you.
i set my machine to inches one time so i dont have to tell it every program. and the T2 is just calling the tool up and getting it ready for the tool chang at the end of that tool. and i think you can have the G40 wear it is "i cant realy remember" i put it in the first line of the tool if i use it.

I only mentioned inches and metric thinking maybe you had done another job in between in metric which would explain why the other machines were working.
The program seems fine then. I'm used to Haas where it looks ahead for the next tool and changes the tool turret accordingly.
is your Haas a side mount tool changer????

Comped in Y&Z? Sounds like G19 might have been active. I don't see a G17 in your program anywhere...
Question is does it have to comp. x&y in this case?

so, your at Y1.04 when this program starts?
Your original post said:
"But then the control started to comp. in two axis y&z"
Is this what happened?
hi, kolodok
It seems your program is wrong! if you are taking internal cut
your program:
N10G0G90T1 G40 (should be here)
M6
M1
M53 (rotary table unclamp)
N100G0G90G54X-.04Y1.04A0.S300M3T2(T2 next Tool)(We are running imperial only, so machine ist set)
M54(rotary table clamp)
(T1=1.0 CARBIDE ENDMILL OR INSERT CUTTER W/.250 RAD.)
(D40=1/2 TOOL DIA.)
G43H1Z2.5M8
Z1.34
G1Z.735F20.
G41D40Y.49F1.1(Problem in this line machine moves both axis x&Y,did not do it befor)
X13.11
G40Y1.04 (this should be minus value)
G0Z2.5
Note you have commanded Y.49 movement, its less then your cutter of 1/2, its not possible....... or you are moving in Y+ direction (right!) to take cut using compensatation G41 and after moving in x13.11 you are leaving compensatation G40 and Y+ 1.04 this is wrong.... you must have to leave cutter compensatation in Y- direction ....
so i can say that it should be in Y-1.04 .... then it will works ok...... this all are my daughts ok....
Don't forget to add the tool nose radius size in the Offset Geometry as well as the tool tip designation 0-9
tip 3 for OD's tools G42 turning toward the spindle
tip 2 for ID's G41 boring toward the spindle
Cheers!!!!!!
