Rads and Chamfers Fanuc Parameters 8134 3453

Messing With Parameters Can Be Fatal!!!!!

To change parameters you need to go to the setting screen in MDI. Now put a 1 in the parameter write box.

Rads and Chamfers Fanuc Parameters. Today we are going to change the parameters that make ,R and ,C work this means you can program point to point and just stuff in some rads and chamfers as an afterthought.

Here’s an article on it if you want to use it

Fanuc have two ways of putting on chamfers and rads and that’s where the confusion lies.

Just do as you’re told (oh and read this article)

So in Parameter 3453 you can set bit #0 (CRD) to a 1 this allows what Fanuc call “Direct Drawing Inputs” to work.

Also in Parameter 8134 set bit #2 (CCR) to a o

Now don’t let the description put you off this turns on the crappy one that uses R and R- and K and K-. This only works on 90 degree corners and unless you won Mastermind I wouldn’t even try to understand how it works.

Trust me it’s shit

Anyway Rads and Chamfers Fanuc Parameters 8134 3453 all sorted!

Isn’t it just great to sort out those annoying problems?

Oh just one other thing before you go off and cripple your machine forever.

Do yourself a favour take a picture of the screen before you change a parameter.

If you aint got a camera then you must have a piece of paper.

Even better back everything up.
