Aggerate Head Information???

[crazy^millman]

Has anyone ever got this to work that does not work for a dealer and has inside information?? I can get the MPGEN5AX post to output the right code somewhat. Took some playing with it, but I can get use able code to some extent. I went digging in the 5 axis router post and did not find anything about the aggerate head in there. I looked in the 4 axis router post but says this:

quote:

---

# This is a 3-Axis post, with C-Axis Aggregate support. Additional

# rotary axes are not supported.

---

Now if this is added to a post that does support addition rotary axes will aggerate head work?? How much do I rob from the router post?? I am working on it, but not sure how much I really need.

 

Any guidance would be greatly appreciated. If I figure this out I will share what I come up with.

Don't everybody jump at once.

 

I turned the router post into a Mill post and used and to no luck getting correct output with the Aggerate head.

I've used it on several ocassions. Let me know what your tryin to do and I'll see if I can help you out.

Just trying to do some inside surface/kellering machining as well as a Cam detail no the inside of a part.

Setup post for angle heads

 

Are you using a Router post or a Mill post? If you are using a Router post, look for a post "switch" in the variable initialization area:

 

use_ra_offs : yes$ #Override Work Offset with Aggregate Offset Register

 

This tells the post to use the ra_offset$ value rather than the workofs$ value (both are available in the .nci file).

 

If you are using a Mill post or your Router post doesn't have that option, add the "switch" and add the following line to ptlchg1002$

 

if ra_type$ | ra_head_grp$ & use_ra_offs, workofs$ = ra_offset$

Thanks Don.

 

I was using a Mill post, but after looking at everything I needed to add to it from the router post I just turned the router post into a mill post. I will look for this in the router post Thanks again.

[crazy^millman]

That was in the router post so not sure where to go next. I am using a 5axis swarf toolpath and it look great on the screen, but getting the correct code well that is a different story. I am going to try different toolpaths and see if they work.

 

Thanks again Don.

Keep me posted.

[Don S at Barefoot CNC South]

Ron have you set it up in your machine defs?

I had to go to my reseller to customize my post for the aggregate head to output in the right axis. If i'm not mistaken the mpmaster was close but the code was swapped in the axis. It may have been a diferent post. Possibly 4th axis. And they did it for free!

[crazy^millman]

Yes I have it set-up in my Machine Def. Had to do that in X to call the tools to use. I will mess around with it tonight somemore. The sad part is the toolpaths for the part were pretty easy it is trying to get the correct output that is not.

[doyleg]

if you can't get the right code to output, see what the axis callouts are and rotate your toolpath with transform toolpath. i was able to do this until my post was fixed to give me the correct output.

[Post dept]

Yeah, it's really 100% handled in the post. You've got to handle the rotary axis and tool comp in the XY plane to start. Then, you need to make arcs work too.

just wondering if anyone got anywhere with this.im having to do some machining with a 90 deg head on a verticle and had to use a router post to get started and hand write the rest.

[gcode]

I took a 3axis VMC machine/control definiton

and a 4 axis router post and got good numbers without too much trouble.

What I really wanted was a 4X HMC and a RA Head,

but that makes 5 axis and I didn't want to mess with it.

I do the regular 4 axis work with my regular 4X post and add a new machine group and a WCS shift for the RA Head work.

Mike,

You can use the 5axis post that you have to accomplish your programming with a 90 degree head. I have been drilling and tapping the ends of long parts with a 90 degree head here at my new job with the post that I wrote. You just need to go to the misc. values and and set your misc real value.

 

Hope this helps!

what do i have to do to make it work for the hass mills.do i just turn off the a&c axis.

[mgsanchez]

Mike,

 

You can't really "turn off" your A&C axis'. You will have to just delete all your A&C outputs, (they should post as A0 and C0). You will have to approach your c-planes and t-planes a little differently than you do on the Mazak. You will also have to delete your G61.1 and the other garbage needed on the Mazak and not the Haas. Then go to the misc. values, then misc reals, and set as "90".

 

On the new post that I wrote I don't have to worry about my 4th and 5th axis outputs (A&B in my case) since I am doing this on a VR-11 Haas 5 axis. The other thing I have done to this post is output for a HRT310 Haas rotary as a 6th axis using a misc. interger. The 6th is only positional connected to the RS-232 port.

 

Hope this helps

Mike

i tried posting it this morning and i can live with deleting all the stuff i dont need but the xy&z values came out for the rotated trunion and not like i get out of the router post.i will have to work at it some more.

thanks

This is where you have to approach your "plane settings" differently than you do for your Mazak in order to get the correct X,Y, & Z outputs. In addition, you will not be able to use canned cycles, i.e. G81, G83, etc. with your current post.

 

Hope this helps

well it looks like i wont be able to do this with the post i have.talked to the reseller today about the other issues im having and i really dont think it will work.im waiting on a quote now but think this will basically go no where and just have to do things the hard way.

 

thanks

You should be able to. I am using the same basic post that you are. Mine just started out as the sample post for the v9 WCS tutorial. I just re-wrote it for the Haas VR 5axis.
