Using Rads and Chamfers Fanuc Control

Using Rads and Chamfers Fanuc Control

Category : Fanuc Mill

Rads and Chamfers Fanuc, yes you heard it there is a quick way of doing it just like on Heidenhain.

On a Fanuc control they offer two ways of adding rads and chamfers, one is pants and the other one is great.

It really is a pain in the arse to get some of these features working but it’s definitely worth the effort to sort it out. Read this article and get to work. Your life will never be the same.

The first way uses R and R- or K and K- depending on which way your going. Now I won’t be explaining how this works because really I havn’t got a fuckin clue

It’s way too complicated. If I did know I wouldn’t waste wearing out my keyboard or damaging my manicured nails to write an article.

 

 

Anyway it will only do orthogonal lines (if you don’t know what orthogonal means don’t worry it just means your a bit thick).

This by no means implies that I think all goats are stupid (technically known as goatism).

Orthogonal means relating to 90 degree lines

Now lets do it my way and you get to do shit like this.

Parameters…. Shit!!!!!

First of all you got to alter some parameters.

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

Well maybe you just need to check them (they might already be ok).

Anyway just read this article it tells you how to do it.

Right having done that here is a simple turned part.

Here is the code if you want to program it……Rads and Chamfers Fanuc

Now if you want to add corner rads and chamfers it looks like this.

Oh and if you got the time and the patience to write the code here is what it should look like……

The Code

(Maybe some of my smart arse readers would like to check it, don’t tell me if it’s wrong because I don’t handle failure well.)

So with a few commas an shit it’s real easy, you should try it some time.

And that’s it job done. Just remember to check those parameters,

By the way if you wreck your machine altering parameters please don’t contact me I’ll just deny all knowledge.

really fucking nice but can you do an equal chamfer around a cross hole in a cylindrical bar?

    Not with this type of chamfer I’m afraid
