Measurement resources selection is a key issue in measurement process planning. As dimensional measuring equipment (DME) becomes available in ever-broadening ranges of versatility, accuracy, and complexity; however, optimization of resources selection for a supplier network becomes increasingly difficult. Dimensional Measuring Equipment (DME) is hardware and software used in a measurement process, e.g., a coordinate measuring machine, fixture, gage, probe, probe extension, stylus, probe tip, laser scanner, tracker, or theodolite. The selection is based on characteristics, tolerances, and datums of a part design. DME with optimized accuracy, versatility, and complexity will enable metrologists to measure dimensional and geometric characteristics of a part with less uncertainty, time, and costs. Consistently selecting the right measurement resources is the goal of all the Original Equipment Manufacturers (OEMs). gas monkey live Measurement process planners usually create rules to help selecting appropriate DME.

Another key issue is to determine a measurement strategy, i.e., what to measure and how to measure it. Selecting what to measure could include determining dimensional and geometric characteristics of a part in measurement processes. Characteristics include dimensions, tolerances, metrological features, and datums. gas mask art Defining how to measure includes specifying where to take samples and with what dimensional-metrology systems, such as coordinate measuring machines, dimensional measurement devices, and hand-held gages. Measurement process planners usually create rules to help determining measurement strategies for features.

The Digital Metrology Standards Consortium’s (DMSC’s) Quality Information Framework (QIF) Rules Working Group develops Rule Types and eXtensible Markup Language (XML) Schema in the QIF standard. The goal is to develop a rule model, i.e., the standard of representing rules used in inspection process planning. The latest 3.0 version is an American National Standards Institute (ANSI) standard and was submitted to ISO/TC184/SC4 for a fast-track approval. One of the key functions in QIF is measurement rule types and XML schema, i.e., QIF Rules. gas relief while pregnant These rules provide industry with a standard way of representing and sharing dimensional measurement strategy and resources selection rules in a supplier network. For example, an OEM can specify what type of coordinate measuring machine, probes, and probe tips can be used based on the tightest tolerance, smallest internal feature size, longest internal feature size, feature orientations in a setup, the part bounding box sizes in X, Y, and Z, and measurement requirements.

Part designers and quality engineers in manufacturing industry will find the QIF Rules standard useful. The standard will enable them to share Model-Based Definition/Product Manufacturing Information (MBD/PMI), measurement requirements, and measurement rules with their suppliers so that they will select capable measurement strategy and equipment to inspect dimensional characteristics of parts to ensure quality (see the figure on QIF-enable Rules Sharing). electricity generation by country QIF Rules Used in Measurement Planning

Why is DMSC/QIF attending? When asked about the importance of attending this year’s IMTS, Curtis Brown, Principal Engineer at Honeywell FM&T and President of DMSC commented: “DMSC represents some of the most innovative, progressive, and advanced organizations in the world today, each on the cutting edge of research and technology in the field of dimensional metrology. Attending IMTS puts us in direct contact with the newest companies expanding into the field of dimensional metrology applications. We constantly seek opportunities to share the importance of standards which ultimately benefit manufacturing on a global scale.”

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

The Dimensional Metrology Standards Consortium (DMSC) hosted the 2017 Quality Information Framework/QIF Summit October 3-6, 2017 in Golden Colorado. Our meeting coincided with the 3D Collaboration & Interoperability Congress (also known in the trade as 3D CIC). In 2018, we plan to meet again during the International Manufacturing Technology Show (IMTS) in Chicago, Illinois – so mark your calendars for that event.

While in Colorado in 2017, we had a full schedule including two days of round-table discussions with the QIF Working Groups, a full day of QIF Symposium meetings, and ended with the official DMSC meeting on Friday including a lively panel discussion. electricity in india first time It was several days filed with robust conversations, idea and information sharing, and advocating for broadening the implementation of QIF.

Many thanks to Jennifer Herron and her team at Action Engineering for the great work they did hosting the 2017 3D CIC event, and allowing us the space to bring the important discussions around QIF into the same collective conversations. We look forward to seeing everyone in Chicago at 2018 IMTS. Reach out to us if you have any questions on how you can help advance QIF in the workplace. Filed Under: News IMTS 2016 QIF Demonstration
