Getting Error while scanning

TAMIL
Hi Guys,
We have a scanning error in a controlled program. The starting point of the scanning surface goes to opposite surface and then it runs normally, All the programs which have scanning same like this gives some trouble to us nowadays which we are using more than a month. I have attached the image in which you can clearly know about what i come to say.
So do u guys have any idea for this problem???




  • I cannot fully tell from the picture as it is too small, but I would guess this is a Find Noms error.

    What value do you have your find noms set at? Something like this can happen when either the tolerance is set too high, or the part is very thin and thinner than the tolerance value.
  • Thanks for the response and we have same find noms value for all the programs in this family and the programs all are running more than a month without any problem but now error occurring, i don't know how it happens when a program is running regularly???

    it could be that before today you have had very little error in the part but now you are seeing bigger errors which is causing a problem, I am not saying 100% it is the find noms tolerance but it is something to think about.

    What is the tolerance and the other scan settings like speed etc?
  • I noticed your origin is a midpoint of the scan. Is there a possibility that your vectors are flipping in your alignment? If you rotate about a line that starts and ends in front of and behind your tetrahedron, and that line is .000001° positive or .000001° negative of the previous alignment, your rotation tetrahedron will literally flip 180°. It does absolutely bonkers things to your routine. To fix, you should make a rotation feature with absolute vector direction radiating away from your current origin, for all alignments.

    Not hard to do, just hard to explain given the flexibility in how we can establish alignments and utilize multiple types of features for alignments.
