Having the capability of turning a pattern into a subroutine

[Anonymous]

It would be when you create a pattern to be able to put it into a subroutine with its own WCS. When you build fixtures offline it would be nice to be able to adjust the coordinates Kama otherwise you have to adjust your model to match your fixtures.

Also in the  WCS offest it would be nice to be able to put in, G154 Pxxx instead of the need to add XXX plus 6 = XXX

[Steinwerks]

"Also in the WCS offest it would be nice to be able to put in, G154 Pxxx"

With regards to this, it isn't really feasible. There are plenty of machines that don't use that sort of offset numbering. I have seen requests for a default output of G154 P(WCS) though and that's not too difficult a post mod.

[cj.abraham]

We have a post that will output operations as subprograms. Below is sample code from said post. Is this close to what you are looking for?

To be fair the subroutines don't work like they need to. If you only have two parts on your table (don't know about more, we never run more than two), instead of ordering so that the spindle starts and putting all locations in a sub run after the WCS is called, it creates subroutines for each toolpath instead of one sub for all WCS'. I never even bother trying them anymore.

[cj.abraham]

@Steinwerks This was just a sample of how we can post using sub routines. We can modify the post so that the order is one sub for each WCS as you suggest.

Mind sending me that one? Because this is what I get (and yes, modified post built on the second to newest Haas milling post, I can send it to you if you want to see it):

I already get one subprogram for every WCS, and I don't want that. I want one sub for ALL WCS'.

Maybe this belongs in its own thread.

[cj.abraham]

If you wanted one sub for all WCS, wouldn't you just post the program for one part, remove the offset callouts, then make a new short program that calls out the posted program for each offset you want?

This is very much getting off topic from the Idea title.

[Anonymous]

Subroutines are easy doing a subroutine for a pattern is different, for instance if you're running a back-to-back vises they are a 180 degrees opposite of each other.

[Greg_Haisley]

The proper way to achieve this is in the UI. So all different scenarios can be addressed. The settings in the UI would be passed to the post.

This is the way other CAM packages have solved this issue. See Gibbs CAM, Delcam and other high end CAM systems.

I believe the use of sub-programming in the HSMworks was not thought of from the conception of the product. The whole crux was to get the adaptive HSM strategy out there IMHO.

Constantly customizing posts is not the intuitive way of getting this done IMHO.

[AchimN]

We will look into this.

[bob.schultz]

We have modified the standard subprogram logic in the Haas UMC-750 post (initial post for testing this feature).  If anyone would like a copy of this post to see if it matches what you are looking for in subprogram support, then please PM me with your e-mail and I'll send you a copy.  Even if you don't have a Haas UMC-750 the logic is pretty much the same as it would be in other posts, so you can visually check the output and see if it is along the guidelines of this request.

The logic used will create a subprogram for the first operation in the pattern and then perform the tool-change/WCS-change and then call the subprogram for the rest of the operations in the pattern.  The operation in the pattern is output in incremental mode.  It supports translated patterns and patterns that change the working plane as long as the resultant output is a simple translation from the first pattern object.

[bob.schultz]

Subprogram support for translated patterns and multi-hole cycles has been added to the latest version of the generic fanuc.cps post processor.  You can visit the Post Processor Forum thread to see how it has been implemented.
