Turning using a G50 or a G92

[camtd]

I have two programs that I am using for a reference. One has a G50 and the other has a G92 if use for setting the tool coordinate system and max. rpm would the only difference be if you are programing for a Fanuc A,B or C Gcode system?

Does one Fanuc Gcode system work on all Fanuc controls?

Which sample would be recommended for most Fanuc lathe programs?

Thank You

Yes to the A,B, and C code system question. Most Fanuc controls are set to use system A.

In general terms, Fanuc programs are transportable across controls. There will be some differences with regards to OEM assigned M functions, but the programs will work without too much editing.

Of the two examples listed, sample 1.

If its an Oi control you have then its likely to have geometry offsets, and automatic coordinate system setting was available on these controls if they didn't have work shift offsets. If this is the case, use geometry offsets and work shift or automatic coordinate system setting instead of G50 for coordinate setting; its a lot safer than using G50 coordinate setting.

G92 on a Fanuc control is a threading cycle on a mill it is like a G50 on a lathe. Check this: G92 Example

Besides being an ancient Thread you've dragged up, I'd suggest you read the Thread first as your reference to G92 in the context of the Subject Thread is completely incorrect.

Excuse me. Did you even bother to read the post!? You have obviously confused a G92 Threading Cycle with a G90 Code. Duh!

Yes I did read it, quite thoroughly in fact; but clearly you haven't. Following is most of the OP's original text. You will notice that the G92 in Sample2 and highlighted in Red, is being used for the same purpose as G50 also highlighted in Red in Sample1. G92 is used to set the Coordinate System and to clamp the Maximum Spindle Speed in Constant Surface Speed in Fanuc "G" code System B and C. G50 is used for those purposes in Fanuc "G" Code System A.

G90 doesn't enter into the argument whatsoever, except that it's used to set Absolute Mode when the Fanuc Control is set to use either "G" Code System B or C; there is no confusing it with G92. Obviously you're totally confused. You dragged up an old Thread in your Post #3 to advertize your software, but the main thing that's on display in your Post #3 and #5 is your lack of programming knowledge.

Duh!

Just like that other Spambot MetalZilla, you've dredged up an ancient Thread to promote your own web site. The OP's Thread is specifically about the use of G92 being used to set the Coordinate System of a Lathe control; it has Zero to do with the G92 Threading. Clearly, one of the machines referred to by Poster camtd, must be set to use "G" code System B or C.

Just like Spambot MetalZilla, you should read the Thread.
