TEST .STP Model for software validation

[CAM-mando]

Hi folks,

 

Any Boeing suppliers here that have been through a DPD/MBD audit to D6-51991?

 

The standard requires that we either validate each translation or "validate" our software. We are using exclusively .stp files provided by Boeing and intend to simply perform a validation of each new software revision using a test model. Does anyone have a step file already available for this purpose? I am assuming our test model should represent all possible feature types but in step land I am not sure what that means specifically.

 

Any experience in this area would be appreciated.

 

Thanks

I think you are addressing two different aspects of DPD:

1) Model Validation:

A method of validating a translation from the originating master dataset received from Boeing.

This needs to be done for any model translated from the master dataset received.

This can be a point cloud check, or a software validation tool like Kubotek Validation tool. per section 9

 

2) PAS Software:

A method of validation of your CMM (product acceptance) after update/upgrade/ maintenance etc of CMM software to assure that calculations haven't changed.

This can utilize a cheeseblock and a proven part to compare results after a change to CMM system software.

PAS also includes inventory control of PAS equipment, temperature control, drift points and more per 7.2

 

There is more to DPD, but I think this covers what you asked.

 

I've been down the DPD road a few times, so ask away.

I know that Crazy millman is also versed in DPD.

For Boeing Philadelphia the validation method for step supar files is "As Received" which I understand to mean individual model validation is not required. Any PAS software including CAD does need to be validated however.

 

I am familiar with teh Kubotek product and if required to provide individual model translation validations will go that route, but thus far I am told it will not be required for our work. All I am asking at the moment is if anyone has a test model they use for PAS validation. Of course we can create one or use a sample Boeing file but I wasn't sure if there is a generic test model floating around of some sort.

With our Zeiss, we got a cheeseblock and model with the CMM and used that.

That is the most common for PAS that I know of...

Is there and echo in here?
