Size doesn t matter

Hello,

 

I ve a part too big to be mesured in one time, I think I will mesure It in two times, through the two red circles I hope Accessible in the two postitions, and finish the rapport with excel and a calculator.

So do you have good practices, or advices  to do this ?

The Base Alignment match function allows the part to be moved and everything measured in a single measurement. I believe the exact details of how this works are explained in the knowledge base.

Three hours to test base aligment match, and it still goes wrong, the last problem is the CMM after the match going to mesure or 10 cm above the part or 10 cm in the granit :)

I don't have much time so I 'll do with two programms, and a few PCM and it will be ok.

You need to add Z points to properly control the Spatial Rotation and Z Origin for the Base Alignment Match. I've used it with great success on massive parts with small tolerances.

it's worth with  Z points, but I've only a very tiny zone of coverage before and after the base alignement match, and the CMM don't plap the diameters at the good place and collision ...

Where are your datums?

 You may need to perform multiple Base Alignment Match then as what you currently have isn't stable enough. You could potentially use something like the granite to help you. Either way, garbage in = garbage out.

Here is the Base alignement Match with some Z points on the granit. I mesure this in manuel, and the CMM collision at the first diameter (try to mesure in full width).

I  don't see where assign XY to diameters and Z To points. for me  is to calypso to do that ?

 

the parts are going to the customer, so I will try another time with another part ...

thanks for your time

For anyone who comes along this post with similar questions. Here is an article that explains how to use base alignment match: https://portal.zeiss.com/knowledge-base?id=522718 - it sounds like in this case, though, it is a matter of what elements are selected to get the best results.

Caitlin I have always wondered about this and never really had a clear path for doing it. So thanks for highlighting that resource because I think it will help me very much in the future!

Maybe I found something interesting in this article it is said that "the circles need to be PROJECTED TO A PLAN ON THE PART" 

 

 ZEISS Portal  "Multiple setup in one report - Base alignement match"

 

secondary question : how do you paste a web link in this forum, when I copy/past  the adress it paste "zeiss portal" !?

Another try  (other part) without succes, I 've done a large surface of recovery, projection of the two circle, put Z points in first, and the CMM mesure the Z point , and try to mesure the first diametrer 1cm beside this position.

 

I have no guide when I move the part, Have I to respect the spatial rotation of the first Alignement, does it matter if I move the rotation slightly ?
