Manufacturing simulation - show thickness by color

Hi,

I have a problem with manufacturing simulation. As you can see in attached picture it's inaccurate and after selection of ,,show thickness by color" I can see negative values of thickness. I checked all tool paths, I tried to run this animation on another computer and on newer version of NX. For everyday I use NX 7.5.

Re: Manufacturing simulation - show thickness by color

Hi,

 

Have you tried to increase IPW tolerances ?

 

Preferences -> Manufacturing -> Geometry tab (in NX11, not sure where it can be found in NX7)

 

Increase needle count or decrease needle distance.

Re: Manufacturing simulation - show thickness by color

From the picture, I would say the IPW tolerance is too coarse for the size of the part. I would call GTAC and have them do it in NX 11, and see the results there. There have been many IPW improvements (and tolerance adjustments) since NX 7.5 was released 6.5 years ago.
