hyundai help

Hi to all,

We have a new hyundai kia skt21lm lathe with a fanuc oi-tc controller and I am trying to find out how to use the auto chamfering function.

The book says to use an I or K value with sign to indicate direction of chamfer but it is not working.

Thanks.

try c with the value for the chamfer
for exampe
G1 X100 C2(chamfer 2mm)
G1 Z-.....
etc

Thanks for your reply Ruud65,
The lathe we have has milling and the c axis refers to the main spindle axis, so I am not able to use c for chamfering as well a the main spindle without getting an error message.
I am not sure what else to try!

1. What is the error message?
2. Are the 2 lines single axis moves and perpendicular to each other?

Dcoupar, I got an error 197 - c axis commanded in spindle mode.
Reading a little further through the book it said if I want to use c for chamfering to change parameter 3405#4 to 1 and yes, that does work.
But now when I want to use the spindle c axis I get an error message - error 055 missing move value in chf/cnr.
I guess instead of calling for c axis I could call it H axis.

I believe you should set #3405.4 back to 0.

You should use I or K for chamfer amount and direction.

H is probably already used for incremental C. Back to your original problem: You said, "The book says to use an I or K value with sign to indicate the direction of chamfer but it is not working." Please post that original code, and explain what happened when you tried to run it.

I tried
G1 X85 Z0
G1 X100 K5
G1 Z-25
all it did was move to X100 no chamfer.
So then I tried K-5
same thing and no chamfer.

If your using some canned cycle of some sort it is usually called up with some G code?

Kinda old post
Try using ,C-5.
We have a Fanuc control that uses ,C and the other uses I and K, annoying since we can't use the same programs in both machines.
Anyone know how to fix this? Can't see any difference in the program parameters, must be somewhere else.
