Coordinate Metrology Society (CMS) Introduces Level Two, Device-Specific Certification

Untitled-1The Coordinate Metrology Society will launch the Level Two Certification during the 2014 Coordinate Metrology Systems Conference (CMSC) in July 21-25, 2014, in Charleston, South Carolina.  The Level Two Certification is the second in a series of device-specific, hands-on performance assessments. Last year, the CMS introduced the Level-One examination, which is a proctored, online assessment consisting of about 200 multiple choice questions covering foundational theory and practice common to most portable 3D metrology devices. This year, the organization will roll out a Level Two examination on a portable articulating arm (coordinate measuring machine), which is a practical performance assessment. The prerequisite is a Level-One Certificate and 200 hours a year of documented use of the device or technology.

During the Level Two assessment, the candidate will use the metrology instrument to collect a series of measurements on an artifact, and then analyze specific features of that artifact. An expert proctor will observe and evaluate the candidate’s technique and accuracy of measurements. The main performance areas are arm handling, probing techniques, parts set-up, and point spacing and distribution.

These measurement operations will be conducted within a particular time limit. The candidate’s performance will be evaluated in a series of several tasks, including setup, probe compensation, and performing field checks of an articulating arm including a basic operator repeatability test. The operator will perform a relocation and a probe change, and measure dimensions, angles, feature forms (including flatness, roundness), feature orientations, position features and a surface profile. Many of the API employees are currently level one, device-specific certified, and will become level two certified later this summer.
