Decisions affect data
A new study by the Coordinate Metrology Society (CMS) looks at how decisions made during and after measurement affect the final measurement result.

The 50-page report entitled “Non-Contact Scanning: How Data is Affected by the Decisions We Make” details the results and analysis of the study and is now available for CMS members.

The study was developed to support the CMS Level II Certification Examination development process, which will culminate in the industry’s first instrumentation-based Certification program for portable 3D metrology. The study’s main focus was to evaluate how professionals in the metrology field work in diverse industries such as aerospace, automotive, power generation, and more.

The interactive study was carried out at last year’s Coordinate Metrology Systems Conference (CMSC) in San Diego.  Over a two day period, CMSC conference attendees participated in the data collection activity in the Measurement Study booth. The objective of the study was to engage the CMSC community in the practical methodology required to support certified operators and programmers. In addition, participants were asked to evaluate the appropriateness of the tasks in relation to the CMS Certification development.

Four stations accommodated participants carrying out practical tasks using a portable articulating arm and a scanning system. Six Analysis Stations were available to observe decisions made while interpreting data, and examine how those choices can influence measurement results.
