If you're referring to the chamfer-out at the end of each pass, according to the manual, the angle is "approximately 45 degrees", and I'm pretty sure it's not adjustable by parameter.
I have a YCI TC26 with a Fanuc 21I. Can anyone tell me what parameter sets the automatic retract angle in a threading cycle.

You can only change chamfer distance.
Hey i found the paramiter, it is 1530 you can't change the angle, but you can change the size. i set it to 0 and it worked great! i believe it only changes G76 and G92 threading cycles.
In G76, chamfer distance can be explicitly specified, which, I believe, would override this parameter. (Incidently, it is 5130)
There is a parameter 5131 also for chamfering angle, but I have never tested it.
It is generally believed that the angle is not adjustable. Somebody may please check and report the finding.
My mistake. Parameter 5131 is not listed in the 21T parameter manual, but is in the 21i-T parameter manual.Originally Posted by sinha_nsit
Actually, this is a mistake perpetuated by Fanuc. Even i-series operator's manual says that the angle is approximately 45 degree. I also believed this until I saw parameter 5131, accidently.
It is a fact that even though Fanuc does take care to enhance the software/hardware capabilities of their products, they do not always incorporate the changes/enhancements in their manuals. Only paramater manual remains updated.
Type 1 or Type 2 programming? If you don't know redily, does your machine require 2 lines to begin a canned cycle, for example:
G76 P010060
G76 X1.500 Z-1.5.........
Only needs one line to star canned cycles.
