3 Axis Fanuc Post Modification?

3 Axis Fanuc Post Modification?

3 Axis Fanuc Post Modification?

(OP)
Hi,

I downloaded the Fanuc 3axis in post from the library but it needs some modifications. I designed a quick part in NX and put tool paths on it and I did the same in Mastercam with similar toolpaths (we have a working post). See the code below. The G100 and G200 lines are subroutines within the control. This is the G100:

I have looked at the post builder but I could not make it work. Any ideas?

Thank you

John



RE: 3 Axis Fanuc Post Modification?

Have you take a post builder class?
The Documentation is very detailed. The changes your looking for seem fairly simple and you may find other posts in the library that better fit your needs.
the G100 & G200 could be insert from NX or customized into the post. Have you looked at http://community.plm.automation.siemens.com/ or http://community.plm.automation.siemens.com/

there are several tips on Post builder.
