The American National Standards Institute (ANSI) Approves New Quality Information Framework (QIF) v 2.0 Standard


New QIF™ V2.0 Standard:  A Major Breakthrough for Manufacturing Quality
Provides Complete & Accurate MBD along with many other enhancements for the Metrology Industry


Burleson, Texas, USA November 23, 2014 — The (DMSC, Inc.) Dimensional Metrology Standards Consortium announced today the American National Standards Institute (ANSI) has approved QIF v 2.0 (Quality Information Framework, version 2.0) as an American National Standard.  This new standard enhances the previous ANSI Standard, QIF V1.0 containing quality planning and measurement results, by providing a complete and accurate 3D product definition with semantic geometric and dimensional tolerances, definitions for measurement resources, template for measurement rules, and statistical functionality.  All of this to satisfy the digital interoperability needs for a wide variety of use cases including feature-based dimensional metrology, quality measurement planning, first article inspection, and discrete quality measurement.

On December 19th, 2013, The ANSI Board of Standards Review (BSR) approved QIF v1.0 as an American National Standard. This new standard provides, quality measurement planning (QIF Plans), first article inspection (QIF Results), and discrete quality measurement.  

QIF v2.0 resolves model-based metrologies primary “pain point,” which is obtaining a complete and accurate 3D product definition with semantic geometric and dimensional tolerances (QIF MBD). It provides cost effective XML exchange of product definition with various conformance levels of semantic PMI (e.g., GD&T) that satisfies many CAD to model-based metrology use cases.  QIF v2.0 also provides a way to define and apply measurement resources (QIF Resources), measurement rules (QIF Rules), and statistics (QIF Statistics) towards generating and communicating feature-based measurement plans based upon a plant, department, or supplier’s measurement resources and rules defined by a company and/or by part type.  QIF models include quality characteristics and measurement features as defined in the ASME Y14.5 specification and the Dimensional Measuring Interface Standard (DMIS).

ANSI approval of QIF v2.0 indicates that QIF has attained a consensus approval from a large number of subject matter experts in the digital metrology industry.  (See “About DMSC” below.) 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. The DMSC has met, and continues to meet the need for urgently required national standards in quality measurement in a timely fashion.   ANSI’s accredited Standards Developing Organizations (SDOs) operate in accordance with national and often international guidelines, and have been verified by government and peer review assessments.

"I am proud of our standards community and the work that we have accomplished with this new standard. This doesn’t replace DMIS (Dimensional Measurement Interface Standard) 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." said Ray Admire, DMSC Treasurer and Chairman of the Quality Measurement Standards Committee."

Manufacturing quality digital information incompatibilities are costly and affects everyone: vendors, suppliers, users, and customers.  And the digital metrology community has lacked an enterprise-wide standards solutions, UNTIL NOW, QIFv2.0, a superior standards-based digital interoperability has been ANSI approved.  Furthermore the QIF enables Manufacturing Quality to join the Model-Based Enterprise next generation of doing business.” said DMSC President Curtis Brown.

The Coordinate Measuring Machines Role In Precision Machining

There is no doubt that the current economy has impacted the health of machining industry throughout the world. The smaller demand for machining products is taking its toll on some machine shops that are not able to find clever ways to operate effectively and efficiently. Some shops are continuing to perform at high levels, and are not experiencing the situation as other have been required to.

There is no secret why some machine shops are adapting to this change and are able to maintain profit even during these difficult times. The best machine shops are finding ways to be more precise. Sure. Precision craft is what most machine shops have prided themselves on for a long time, but the shops that are doing well today are expanding the meaning of this precision into the ways they are running the business. More often than not, this precision in business management means the addition of some type of technology.

The growth in machining is in the field of precision machining. With the automotive industry not performing as it once did, the old machine ships that once were able to press and machine parts within reasonable specifications are now understanding that they need to switch operations in order to stay competitive. Precision machining, that is machining that operates within a tiny fraction of an inch, and has fine minuscule tolerances, is now in high demand. This is due to the fact that many industries such as the alternative energy field need very small tolerances.

CNC CMM PROGRAMMING SUPERVISOR


This is a key leadership position. The CNC Programming Supervisor should have a strong PC-DMIS background and experience with CNC (computer numerical controlled) Programming and ideally NC probing experience as well. We can train on the NC side so that is less important than the PC-DMIS. This can be a Programmer and a Manager, or combination. CNC tools have revolutionized the design process, allowing use of a number of different tools, combining the many into a single "cell", such as using a number of different machines with an external controller and human or robotic operators that move the component from machine to machine. PC-DMIS allows us direct and seamless integration with CAD data, eliminating translation and maintaining the original design intent throughout the measurement process. PC-DMIS provides comprehensive measurement routines for all part types, from the simple to the most complex. This is a key role, as it will allow manufacturing to quickly capture dimensional data, analyze it and act on it to reduce scrap, improve throughput and reduce costs.

Company Information (Specifics provided with receipt of a confidential resume)

The company produces UNMANNED VEHICLES – an exciting time, as the applications cover Homeland Security to Agricultural information gathering, etc.

The company is on the front end of contracts and fully immersed in ongoing contracts. They are willing to relocate candidates on both positions. This is best for people who have worked in smaller, entrepreneurial, dynamic, ever changing and ever creating cultures. They must have DoD experience. They will want to join a company where they can make their mark. They won’t be coming into a fully defined, multi-layer operation.

Surface Normals

Issues When Programming From CAD When Using A CMM

By Mark Boucher, CMM Quarterly http://www.cmmquarterly.com/



There are several issues that arise when bringing a CAD model into your CAD based coordinate measuring machine (CMM) programming software. One of these issues has to do with surface normals (surface vectors). You can bring in a model and the entire model or a portion of that model is visible, but dark (Figure1), or certain sections are not visible at all. This problem arises from the surface vectors pointing in the opposite direction than your CAD system views them. You are looking at the back side of the surface. You must reverse the surface normal (Figure 2). If your software has this capability, you are looking for something similar to ‘reverse surface normals’. This will flip the surface so the front faces in the correct orientation for your software to view the surface.



All surfaces have a front and a back side; a CAD program must know which is which. How is this done? The model must somehow include information to specify the front of a surface. This is done by surface normals.

This is a line perpendicular to the front surface and beginning on that surface pointing away from the surface. Meaning it exists only on the side of the surface that is its front. The CAD system must have this information to shade the model properly. Those that
use a CAD system need this to drive the probe normal to the surface.

Direction vectors have been covered extensively by Richard Clark, his three part series was featured in CMM Quarterly (http://www.cmmquarterly.com/ ). Suffice it to say that these surface normals are what give you the direction vectors from CAD models when programming. If you do not use a CAD model to program then you must calculate the normal vector. Contact rcmetrology@yahoo.com for a Direction Vector Calculator.

When picking a feature off a CAD model the software will extract the normal vector from the CAD surface. As mentioned above you may have the ability to flip surface normals or you may have the ‘view surfaces from both sides’ option. Care must be given to this selection because the surface will be visible but the vector may point in the opposite direction you need to probe the part, your probing direction vector. Just know when viewing the vector after feature selection, that it is correct.
