As the Working Group (WG) Charter was finalized, monthly discussions commenced. These meetings were held at a time of day that allowed participation by the team from Japan and USA-based members of DMSC. The key deliverable by the WG was a gap analysis for non-contact measurement workflows using QIF MBD that would require potential QIF revisions (if any) to support non-contact measurement workflows.

The Non-Contact Metrology WG (NCMWG) has been, through their monthly meetings, working on identifying and setting priorities for specific items that need to be included in QIF. These were initially identified by AIST NMIJ (National Institute for Advanced Industrial Science – a Japanese research facility) and NMIJ (National Metrology Institute of Japan) for measurement systems that are not using contact methods to acquire measurement points. This WG has been made up of AIST, NMIJ, DMSC members, and other interested parties.

The NCMWG has identified possible additions to QIF Resources for the next enhancement of QIF 3.0. A key criterion for each QIF enhancement is “don’t break it.” So these potential additions must be thoroughly evaluated for compatibility with QIF 3.0.
A second set of QIF enhancement ideas was recommended. While desirable, these enhancements are not suitable for a QIF minor revision. They do have value potential for future QIF releases. These items will affect “QIF Plans and QIF Results.” A timetable has not been determined for these potential QIF enhancements.

Additionally, the NCMWG has identified initiatives that overlap the scope of work being done by other organizations, such as ASME, ISO, and JEITA. These features may be adopted through joint initiative projects.

After submitting the above proposals, the NCMWG has met its original Charter objectives and will conduct future meetings as needed.

The post Non-Contact Metrology Working Group Update and Status appeared first on DMSC.

Initial discussions started mid-summer 2020. Later that year, a DMSC Working Group was formed to consider additions to QIF to expand coverage of non-contact measurement devices, such as cartesian-arm CMMs with optical devices, CT scanners, laser trackers, and optical digitizers.

A DMSC Working Group Charter was finalized, and monthly discussions commenced. The key deliverable by the WG was a gap analysis for non-contact measurement workflows using QIF MBD that would require potential QIF revisions (if any) to support non-contact measurement workflows.

The Non-Contact WG (NCWG) has been working on identifying and setting priorities for specific items that need to be included in QIF. These were initially identified by AIST NMIJ (National Institute for Advanced Industrial Science – a Japanese research facility) and NMIJ (National Metrology Institute of Japan) for measurement systems that are not using contact methods to acquire measurement points. This WG is made up of AIST, NMIJ, DMSC members, and other interested parties.

The NCWG has just finished identifying specific goals for Phase 1 (top priority) and Phase 2 (next priority) implementation and consideration of possible QIF component expansion for future releases of QIF.

The NCWG is making progress in determining the future direction of QIF. If you are involved in non-contact dimensional measurement, this WG may interest you or your organization. DMSC membership is not required to participate.

The DMSC commitment to develop needed and relevant standards continues with two new working groups.

Model Based Product Characteristics Working Group (MBPC WG)

The MBPC WG meetings have been ongoing since June 2020, conducted twice monthly for the purpose of developing a draft proposal for a new ANS (American National Standard) for Model-Based Product Characteristics: Nomenclature, Definitions, Symbols, and Practice.
