New arc filter problems

[cobra95kev]

This is the result when I use the new arc filter on a high speed waterline path. It runs an arc right through my part. This did not show up in verify or backplot. Luckily we use Vericut. I would be pretty irritated if this made it out to the machine. Once I turned the new arc filter off the problem went away. I will talk to the boss about sending this in to QC if you guys think it could make a difference and actually improve this type of stuff.

I would talk to your reseller about that. If it didn't appear in the MCAM Verify, you may have a problem with the post.

We got that done at my last job so that

we could send problem files to QC

without violating our contracts with

vendors

 

I would also experiement with arc setiings on the filter page..

try setting the min arc to .010 on the filter page. What usually causes these filter errors is

very small arcs getting turned into large arcs going the other way

I wouldn't think it is a post issue since it only does it with the new arc filter and not the old?

 

I checked my filter settings and the minimum is set to .1 and max is set at 1000.0

 

I think these are default right?

Kick that max down from 1000.0 to 100 or lower. (you really don't need it to make a arc greater than the biggest arc on the part)

 

In a sense you could have mastercam take a good linear move and create a arc move at a 1000 inches, which maybe forcing your tool to go thru the back door.

What post and control? I had something similar recently and solved it in the control def. by turning off break arcs , and allowing 360 deg arcs. (Didn't show in verify but did on a 250$ block of aluminum. )

 

This solution was recommended by my post developer.

 

I've ran about 30 successful programs thus far without a hitch, 10-20hrs run times each

Great tip Chris. Now I remember having to break the arcs into quadrants and NOT allowing 360 degree arcs. Something about the arc filter getting confused if I didn't apply those settings. Sorry Cobra, I forgot all about that. I also reset my arc filter to .010 Min. Rad, and 99. Max Rad since some of the equipment can't handle a 100.+ arc.

We are using the default machine def file. We are posting from NCI code using Austin NC.
