How to do Vision only alignment on Optiv 2Z443 multi sensor

Hi All,
I am wondering if their is an accurate way and how to do a vision only alignment on the optiv 2Z443?? I am working on some very small medical parts with small features that is why I want to use vision only. I have the part just laying on the table with nothing holding it down due to its size so I can't touch with the probe since it is not secure to the table. Any input is appreciated!

  • Jefman is right, you can do a alignment with vision and it does have some accuracy loss depending on the part. The thing that concerns me is that you are not using anything to keep it from moving. What is stopping it from possibly rocking, sliding, shifting, or anything? You first need to have something keeping it from moving, whether that is putty, a corner viewer and a pusher, or something that still allows you to measure everything.

    In regards to the alignment, Jefman is right. You can do all the aligning with the vision, for a plane you would use 3-4 focus points and construct a plane then level, you can use 2 focus points on a edge and construct the line using that to rotate to, and 1 focus point on a edge to lock the last axis. It can be that simple. There are several ways to accomplish alignments with vision only functions, but it is understanding the system and capabilities to know what you are able to do. I will say that some machines (not sure on yours) have accuracy issues more in the Z axis then the X/Y. Like Jefman said you will have to do tests to see what will work. You could do a testing study from probing to vision to see what discrepancy you might run into.

    One last thing, your last comment probably isn't needed. What you are missing is that you may have had 67 views, maybe 67 people are just curious as to what the process would be or are wondering the same thing. This is a user based forum where people are going to look just to see what the questions/answers are because it might help them now or sometime down the road. As you know we are not paid for helping so we will help as soon as we come across the question, if we can. If you need immediate assistance you might want to consider training onsite to help you with your specific parts and machine. You asking open ended questions and then following up with a complaint that no one is helping doesnt make anyone want to help you.
