Nested Subroutines

[Paul McGarr]

Does anybody have a mill post processor that can handle nested subroutines?

[Paul McGarr]

Just to be more clear, I really should have said subprogram instead of subroutine.

 

Sorry

MPFan and MPMaster both handle Subprograms as do a few others thatI can't think of right off the top of my head.

I've tried the latest mpmaster post, and it handles subprograms fine. What I need though is for the post to handle NESTED subprograms. For example, I have a plate with three groups of identical cavities in clusters of eight. I can program one cavity and use the tranform toolpath to get the array of eight, but each group of eight is on another symetrical pattern that I would like to use the transform toolpath on as well. I need to transform a transform toolpath. The mpmaster and fanuc posts show an error saying that they do not support nested subprograms. What do I do other than buying a memory upgrade for my machine?

 

Thanks,

I used to do nested subs on a xxxxor control and it was really easy to do it manually. The reason I did it manually is so I could write the general contour in master cam, set the parts up on the table, indicate their position and loop it to the positions. I had sometimes one outside shape and 5 inside shapes per part and the xxxxor was a memory wimp.

I would do two contours (one outside and one inside) and nest, rotate, rotate, etc., nest, etc.

It got tricky when I ran out of fixture positions and had to start using G92! With more memory I would have set the machine up first, indicated the parts and translate to the positions in MC.

Lay them out in MasterCam. Do incremental code on one pocket and save as a subprogram. Go back and do absolute start positions for all 24 pockets. Then just position and sub, position and sub,........

I have a post that was for a Meldas 300 that I use for a Fanuc 18. I have not used it for subsprograms but the post should be capable of it. We do use a lot work offsets along with axis rotation on each. If you want you can e-mail me and I will send it to you.

Please email the file that illustrates the problem. Thanks.

I think he's trying to do a subprogram transform of a subprogram transform, which isn't supported by MP at this point (not even v9).
