Fanuc Macro and G-Code Programming

[kilogulf59]

Hello to all,

I just joined and hope to get a dialog going concerning the afore mentioned topics.

I've been doing this for awhile, however, I've been out of the "hands on" shop work for the past several years.

Now I'm back in the trenches getting some "trigger time" again and, due to some recent machine purchases, find a need to dust off the old programs.

Below is an example of the type I'm used to, mainly for OKK, Makino, and Kuraki VMc's and B/Mills using various late model Fanuc controllers i.e. 15m, 16m, 160, etc.

There's a lot I do not know as I'm basically self-taught. However, any information or exchange is welcome. I was just beginning to really get into it when I stopped.

Oh, I also used macro variables along with G10's to create some interesting programs.

Hope to hear from you all soon.

Take care and Happy Holidays,
KG59

I do not do any of these programming on the machine. I normally use CAD/CAM system to generate the tool paths. I like to start learning them! Do you have any example for probing?

Hi,

I was looking at your Fanuc Macro and I was wondering exactly what that macro is supposed to do? Looks like it does a hole in a previous hole.

I want to write a macro to do a reduced peck for deep holes.

i.e. 4" depth .75 for the first peck .05 peck reduction per peck (second peck .7 third peck .650 etc.)

until it gets to the final depth, or the peck becomes the same value as the reduction amount.

Have you ever seen anythin like that?

Is it possible to write a M98 on a 160mc (dos version on an Okada) that goes lower in the program M98 P0010 L01 and then returns back to the line below the loop. I swear I have done it but it has been years ago. I don't want to load 2 programs, one in the 9000 area. Should be able to get it all in one program with out a macro b going on?
