machine tool builder and assembly constraint

Pioneer

Hello,

I would like to know if for you it's the same thing constrain or not my machine assembly before using Machine Tool Builder, for example I already have every model in a correct position, do I have to putting constraints or I can let them free?

 

Thank you

i do not have constraints in any of my machine models. Many OOTB do not come with constraints on assembly componenents.

I am not sure If I am missing any functionality if I would have constraints....

The kinematic model doesn't rely on assembly constraints, so just don't use them.

If I remember correctly, they have caused problems in the past, but that might no longer be the case.

I follow the paradigm to use only the mandatory things, nothing more, nothing less.

Thank you,

so I only have to check that every model in assembly are in the correct position without using any constraint.

Correct,

use Machine Tool Builder print for XYZ ABC travel limits and distance of axis of rotatation. 

Save your machine assembly in such position that spindle centerline gage point is in machine work zero position. 

then define your axis as per machine limits...

 

good luck

When I make my machine assembly I tend to use assembly constraints

They are ignored in the machine builder side. No issues

So things got better after NX 2, when IS&V was introduced ;-)

I started using IS&V in NX 3, so I was advised to not use assembly constraints (at these days they were called: matting conditions).

I've only been using ISV since 9, NX9, NX10, NX11 and NX12 no issues.

So, as I see, we can do what we want: for example we can add constraints to arrange machine models and then delete them, or we can keep the constraints without problems.
