Control error or Post error?

[Müřlıń®]

I had a gouge on Surface rough pocket that did not show up in verify and did not give an illegal arc error in backplot.

 

We have Haas controls and I had Arc filters turned on in my post...

 

 

Any way to check the NC file to see if it has an arc error without having reverse g-code verify?

 

This is worry sum for me as I have not had a gouge in 3 years.

 

Perhaps the control just had a moment?

 

The gouges are making an arc, so it appears it was not a strait line gouge...

 

I was using a 1" ball. The screw through the insert is so tight that the insert could not have become loose either...

Murlin,

 

Surface Rough Pocket or the Highspeed Core roughing?

 

the Core roughing has given me this kind of trouble in the past.

Just the plain old surface rough pocket...I don't use any of the HS toolpaths...

This happened to me about 3 weeks ago;

1" Ballnose, Surface Rough pocket, verify good .125 doc, .25 stepover, etc etc.

 

3/4 of the way down big loud noise.

 

 

Tool slipped down about 1/4 inch. Someone had ground the flat on the tool with a pedestal grinder. The screw wasnt even making full contact with the flat. This wasnt in our shop; Live and learn.

 

You might want to see if it happened to you.

We use mitubisi inserts with the screw that goes all the way through and the screw fits the hole so tight that there in no way it could have come out...

 

perhaps it was a rapid feed move and the gouge was deflection?

 

As you can see from the pics there are no anomolies in the verify or backplot path...

 

But it is a one time run. can't see if it does it again..

 

judging from the finish it does look like it was feeding very fast...

 

 

It would have to have done it on the roughing pass when it was conventional cutting, but it would have to pulled about .05" to deflect that much...

 

It gouged in 2 other areas at the same depth cut...

Murlin email me the .nc file "just the code" and your blank size I can verify it for you.

one of my machine defs should be able to run it.

It's OK, Murlin. Just don't charge the customer for the extra work.

I manually looked over the code and could not spot any G00's where they shouldnt be@ X-3.33 at the end of the program...couldn't see anything out of the ordinary that stuck out...
