POST OR PROGRAMMER??

[Incogneeto]

This one should be fun for whoever figures it out. I'm currently connected to Tech support but as yet no answer. This part is fine But for the waterline path cutting the radius with a bull endmill. Backplot and verify seem right. But when posted see photo's.

Thanks Dave

It could be your arc settings. What machine and control are you using?

 

Change you control def tolerances foir arcs. Min 0.01 and Max 100

Post issue.

 

It posts fine on my post.

 

 

[Incogneeto]

Post really? I would bet money I screwed up. And I have done 3D on this post without a hitch. And this one seems so simple????

[Incogneeto]

I'm using a Mori FM-1 Mill Fanuc controls. And i would like to believe you are correct. I was actually hoping it was my fault. So much easier to fix my stupid then the machines or post.

[Chris Rizzo]

What control is it? In the control def arc page set arcs to "don't break arcs" and "allow 360 deg arcs". That has fixed several problems for me in the past.

 

The important question is can you re-run the program with changed settings to test it?

[EX-wccprogrammer]

It probably is your fault.

 

It just happens to post OK for me.  If you have time, I would suggest that you try to find out why it output the code that it did, so you will not get a repeat performance in the future.

Chris is correct on those settings as well as the tolerance settings.

[gcode]

I think your machine didn't like one of the arc statements

It posts fine for me and looks correct in CimcoEdit backplot

 

I'd go out and run the waterline path up in the sky and watch it closely

[Incogneeto]

It's an MSC-521 control

Naw we just put the radius in the lathe . just to get the two parts out. But I'm keeping your suggestions for a retry.It Just freaked me how well backplot did and machine or post just walked away.

[Incogneeto]

That is why I'm here talkin at Ya !!!

Unfortunately, verify in Mastercam will not catch problems in your machine configuration or your post.  NC code verification is the preferred method.  Or, you gamble with your parts.

[Incogneeto]

Ok but do you have to return the settings back after or do you just leave them that way?? P.S. Thanks

I  was unaware of that and I assumed backplot would give me a virtual view of the tools path but apparently not . Good to know!!

Are you doing that through CIMCO??

[Incogneeto]

And Thanks to all of you TON O" HELP !!!

[EX-wccprogrammer]

I use Vericut.  But there is other software that does NC code verification.

[gcode]

In this case CimcoEdit backplot isn't catching it either.

The gcode looks fine

[#Rekd™]

Vericut will not show the gouges either, it may give you a warning though. I have had a few gouges on the machine that Vericut did not show.

 

Leave the settings once you change them.

[EX-wccprogrammer]

Vericut has a feature called Auto-Diff that will show even very small discrepancies.  In 3D toolpaths, you can see the scallops from the machining.

[#Rekd™]

Vericut did not show anything. The code look fine but the controller can not handle the small arcs. The last one I got a warning to investigate a line, the graphics looked great.

[EX-wccprogrammer]

The control definition that you use in Vericut can be adjusted to match the capabilities of the control.  Then it would render properly, would be my guess.  I have seen no issues like you describe in any of my machines.

[Incogneeto]

I've had it veer off on small arcs and sometimes get stuck in a loop but this one wasn't like that it just did a straight move through the part and repeated as it moved down the radius. If you look at the pic it actually worked well for about a third of the radius.

[Incogneeto]

And Tech support completly lost it on this one.

Hello All,

 

It seems we lost the track the original issue from the customer. The reposted output is different from the original NC file. The part shape in Mastercam file is different from the attached pictures.

I use CIMCO editor to backplot the customer’s NC file and cannot find the cutting through.

CGTech sent a guy in and video taped the moves and the control lines. They can't get it to match for some reason, they updated their software but it now gives a warning only.

 

They built the entire control and machine for us.

[EX-wccprogrammer]

Dadunbar, the machine definition and Post work together in many cases.  Unless you supply your machine def and post, it is unlikely that anyone else is going to be able to replicate the issue that you are having.
