QIF, A New Interoperability Standard for Manufacturing Quality Data and New Extensions for Product Definition with PMI

 

On June 19th, 2013, a significant milestone event for data interoperability for manufacturing quality was accomplished, that is the Dimensional Metrology Standards Consortium (DMSC) formally approval four technical specifications that address three critical digital data exchange interfaces for model-based manufacturing quality.  These technical specifications will be initially introduced as an American National Standards Institute (ANSI) standard and will be known as the Quality Information Framework (QIF) specifications.  Quality is not free, nor is it optional but now it can be performed faster, better, and cheaper.  The DMSC is an ANSI Accredited Standards Developing Organization, as well as an A-Liaison to ISO TC 184.

The QIF v1.0 standard defines an integrated set of information models which enable the effective exchange of metrology data throughout the entire manufacturing quality measurement process – from product design to inspection planning to execution to analysis.  It was developed by domain experts from the manufacturing quality community representing a wide variety of industries and quality measurement needs.  QIF models include quality characteristics and measurement features as defined in the ASME Y14.5 specification and the Dimensional Measuring Interface Standard (DMIS). The standard covers a wide variety of use cases including dimensional metrology inspection, first article inspection (SAE AS9102), reverse engineering, and discrete quality measurement.  

Furthermore, the DMSC is collaborating with Capvidia to advance metrology technology and interoperability by extending QIF to create the PDPMI (Product Definition Product Manufacturing Information) format.   PDPMI combines QIF XML schemas with Capvidia’s CAP XML schemas to represent and exchange model-based product definition plus various conformance levels (i.e., technical readiness levels) of Product Manufacturing Information (PMI) that will not only satisfy the CAD to Quality Measurement use case but will meet many other CAD to Manufacturing needs.

This presentation provides an overview of the QIF and an update on QIF ANSI status.  It will also present the current progress of the QIF PDPMI initiative.
