Finally remembered to get a file attached! This happened today on a program that has ran 2-3x previously with no issues. 1765496662.act

Thanks for the suggestion. I have never heard of that type of alignment, so I will look into that!

Wow thank you! What program did you use to make those illustrations? I am sure the cost wouldn't be approved any time soon for me to be able to get it, but it sure looks swell!

Would I need to do anything special to account for the fact that the side plane would not be perpendicular to the table?

It's been a big headache for me and several others too. And it's not just 1 problem - It seems to affect different machines differently. For me, the execution mode is insanely slow. Sometimes it will take a single feature 10-20 minutes to execute.

DWC, That was the answer I needed. Thank you for all the help!

@BlueSky Sorry to be delivering this news - but no.

No, the new datum was never measured for the parts that I need to pull measured points from. Is this still possible?

@Justin Mark Thanks for the edit. I haven't had to do this yet, but it is good to know.

There's no plot function for a free form surface. In very simple terms, you'll need to create a CAD Presentation by starting in CAD > Evaluation > Check Display. Set up the view and other settings. Click Manage views. Create and save a view. Click CAD presentation.,

anyone notice that Can, May, Must = CMM

@BlueSky Was the new datum measured in the old program? If so, yes.

I have the profile option here. Is this the one your referring to ? Where is the enable visual evaluation ?

DWC, Thank you again! To my original post, there was a change within the program after the part was ran to one of the datums attached to the true position characteristic. Is it still possible to obtain x, and y coordinates even after there was a change to those datums? (I was able to get the x,y coordinates for some of the parts since they were ran after the change within the program)

The first message is the more concerning to me. Not reading the chip ID can indicate a lot of different things, but it basically breaks down into not getting the data on the ID chip to the controller. The second message is just something you are going to see from time to time with passive heads because they cannot react to deformations and unexpected locations like an active head can. See https://portal.zeiss.com/knowledge-base?id=443336 for more information.

You can, but it depends on the exact callout whether or not you absolutely need. The primary use case for the best fit bore pattern is to move patterns together relative the the DRF rather than individually.

Do you use bore pattern for composite and single segment position?

That is very helpful!

@Darci Burch Use the CAD file to create a reference point system (RPS) alignment. This is a common alignment system used in the auto industry for things like body panels that lack standard geometries. There are threads on here about RPS alignments in Calypso. I haven't used RPS alignments all that much in Calypso, but I do remember that looping the RPS alignment at least 3X is important. Hopefully someone with more RPS alignment experience chimes in. Best of luck sir.

@BlueSky If you want the coordinates for true position to output into Excel, etc, go to the 'Resources' menu, drop down to 'Characteristics Settings Editor', 'Report', then over and down to 'Additional report'. Select your true positions, and move the 'Set To' toggle to 'On'. Now under the 'Plan' menu you can do subsequent evaluations of all the parts at once.

That's kind of a loaded question because if MMB/LMB is invoked then it would matter if they are evaluated together or not. And then there are the Composite Tolerance scenarios.

Not necessarily. It depends on how many degrees of freedom are constrained on the features. If a pattern of holes is fully constrained to A|B|C, for example, then checking them individually to A|B|C or as a pattern to A|B|C will give the same results, as there is no best fitting on fully constrained features.

I would create my Base Alignment on the side plane with the 3 holes in it, using the plane as spatial/origin (3 DOF), the 2 holes for clocking/ vertical origin (2 DOF). and the symmetry of the 2 holes as the horizontal origin(1 DOF) to center to the part/model. From there you can start to establish other alignments/features to meet your print requirements and/or create more robust alignments that consider datums, etc.

So any position that calls for 2x or more is a pattern then and cannot be position individually?

Just understand the limits of the XXT and you are OK. 🙂 3mm_L.SystemDocumentation.pdf 0.5mm_+Z Tee.SystemDocumentation.pdf 0.5mm_22.5Deg.SystemDocumentation.pdf 1.5mm_Star.SystemDocumentation.pdf 0.5mm_Fixed Star.SystemDocumentation.pdf
