ANSI Approves New Quality Information Framework (QIF) Standard

A significant breakthrough for the metrology industry

Published: Monday, January 6, 2014 - 11:55

(DMSC: Burleson, TX) -- On Dec. 19, 2013, the American National Standards Institute (ANSI) approved the Quality Information Framework, v. 1.0 (QIF v1.0) as an ANSI standard. This new standard covers the digital interoperability needs for a wide variety of uses including feature-based dimensional metrology, quality measurement planning, first article inspection, and discrete quality measurement.

The QIF standard was designed to meet the highest industry requirements and to satisfy technological gaps that have traditionally cost industry hundreds of millions of dollars annually. QIF v1.0 provides a standardized solution for defining and exchanging measurement scope (e.g., bill of characteristics), measurement plans, and measurement results.

QIF aims to define an integrated set of XML 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 and analysis. QIF v1.0 models include quality characteristics (e.g., tolerances) and measurement features as defined in the ASME Y14.5 specification and the Dimensional Measuring Interface Standard (DMIS).

The “Founding Principle” of the QIF is simply this: All information models for transporting quality data should be derived from common model libraries so that common information modeling components can be reused throughout the entire quality measurement process and, as a result, the entire process will be inherently interoperable.

To find more information about the QIF standard please visit the QIF website at www.qifstandards.org. To obtain your no-cost copy of the standard please send a request via email to bsquier@dmis.org.

“I am proud of our standards community and the work that we have accomplished with this new standard,” says Ray Admire, Dimensional Metrology Standards Consortium (DMSC) treasurer and chairman of the Quality Measurement Standards Committee. “This doesn’t replace DMIS but it compliments and can harmonize with it. This new standard infrastructure is expandable to include every aspect of the Quality Information Framework, thus the name. Once adopted by the software vendors, this will allow us to properly use digital models with all the engineering requirements and quickly produce inspection and measurement plans throughout our supply chain (micro and macro), conduct inspections and measurements then analyze and report in standard formats via AS9102 or PPAP files. This will be a huge savings throughout every manufacturing industry in our environment without any cost to the software vendor or user.” 

“This ANSI standard is a significant milestone for manufacturing quality and catapults metrologies applications into cost effective digital interoperability,” says DMSC president Curtis Brown. “We need our manufacturing community to embrace this standard not only as a good technical solution but as the best most cost effective way to do manufacturing business. QIF v1.0 addresses missing digital interfaces necessary for proactive quality within today’s model-centric applications and tomorrow’s model-based enterprise. We are already working on QIF v2.0. Please join us as we progress vendor agnostic interface solutions built upon the foundation provided by QIF v1.0.”

The work is not complete, from the QIF v1.0 foundation. Significant QIF v2.0 efforts are being devoted toward responding to model-based metrologies primary pain point that is obtaining a complete and accurate 3D product definition with semantic geometric and dimensional tolerances (GD&T). QIF v2.0 work for a cost effective XML exchange of product definition with various conformance levels of semantic PMI (e.g., GD&T) will satisfy many CAD to model-based metrology use cases. Additional work will define and apply measurement resources and measurement rules toward generating and communicating feature-based measurement plans based upon a plant, departments, or supplier’s measurement resources and rules defined by your company and/or by part type. Finally, work for QIF v2.0 will address the MIL-STD-31000 terminology and additional non-dimensional measurement applications.

Dimensional Metrology Standards Consortium DMSC

The mission of the Dimensional Metrology Standards Consortium (DMSC) Inc. is to identify urgently needed standards in the field of dimensional metrology, and to promote, foster, and encourage the development and interoperability of these standards, along with related and supporting standards that will benefit the industry as a whole. The Dimensional Measuring Interface Standard (DMIS) is one such standard that the consortium has the responsibility to develop, maintain, and support as well as to coordinate and harmonize with other related standards efforts.
