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.
