CMSC 2018 Presentation - Technical and Procedural Challenges in the Development of ASTM E3125-17 Documentary Standard

The Dimensional Metrology Group (DMG) at National Institute of Standards & Technology (NIST), along with various other organizations were involved in the development of the ASTM E3125-17 documentary standard for 3D imaging systems.  The ASTM E57...

CMSC 2018 Presentation - Automated Transport and Photogrammetry System (ATAPS)

Photogrammetry is often not utilized for certain measurements because of the time required to target the holes and features that must be captured to complete the measurements.   This paper presents a new process created by Geodetic Systems...

CMSC 2018 Presentation - CMM Automation and Optimization using Model Based Definition

CMM programming is currently a tedious, time consuming, and error prone process which requires the active involvement of a highly skilled quality engineer. The GD&T product requirements need to be manually transcribed into the CMM programming software...

CMSC 2018 Presentation - Automated Laser Rail for ADM Calibration

Paul Nichola

ChallengeExisting processes for calibrating ADM laser trackers involves time consuming practices, manual redundancies and large footprints that inhibit an efficient process for sending laser trackers back into the field where they can be utilized by the...

CMSC 2018 Presentation - Experimental Uncertainty Analysis for Nondestructive Testing of the CSX Wilbur Bridge Using Electronic Distance Measurements to Measure 3-D Coordinates of Cardinal Points

A 154 page report by Moreu and LaFave in 2012 explains unique problems railroad bridge engineers must contend with. The gross weight of cars went from 200,000 pounds to 263,000 pounds in the 1970s, and to 286,000 pounds in 1991. The ratio of live to dead...

CMSC 2018 Presentation - A NEW EXTREME SPORT - METHODS FOR CHARACTERIZING CMM PERFORMANCE

The Dimensional Metrology Group at the National Institute of Standards and Technology (NIST) has developed its suite of ultra-high accuracy Moore M48 coordinate measuring machines (CMM) into the premier 3-axis CMM capability in the world for gauges and...

CMSC 2018 Presentation - Long Duration Photogrammetric Monitoring of Turbine Deformation at High Temporal Frequency

As a non-contact 3D measurement technology, photogrammetry has long been applied in deformation monitoring. Applications have ranged from the measurement of deformation of large-scale engineering structures such as bridges, buildings and dam walls, to...

CMSC 2018 Presentation - Development of a hybrid alignment method for a turbine blade using tactile probe and laser scanner

Turbine blade, which is a key component in gas turbine applications, has complicated free-form surfaces and tight geometric tolerances due to increasing efficiency and performance requirements of power systems. Therefore its inspection process is a very...

CMSC 2018 Presentation - Straightening of APS LINAC Accelerating Structures Utilizing a Portable Articulating Arm CMM

William G. Jansma, David J. Bromberek, Jaromir M. Penick

The Advanced Photon Source linear accelerator system utilizes 3-meter long SLAC-type 2856 MHz accelerating structures. Surveys of the APS LINAC indicated distortion in the straightness of the accelerating structures over time, with 7 mm of sag detected in...
