2020 CMSC PRESENTATION: CMM Verification of Low Pressure Turbine Blisk under Spin Testing of a Small Turbofan Engine

Suneel Kumar, Marakandeya V, MuralidharanV, Sreelal Sreedhar

Spin testing testing of the integrated bladed rotors or blisks is being increasingly used for the better understanding and validation of life and integrity. The test is carried out in various steps and goes thorough rigorous monitoring and inspection...

2020 CMSC PRESENTATION: Case Study of a Fuselage Join Automation

Rob Flynn, Nathan McRae, and Spencer Thompson

A large jet fuselage consists of forward, center and aft sections which must be joined together.  The join process calls for a rough move to a “stage” position, automated measurements, and calculation of a transformation matrix to yield a move to...

Beyond Best-Fit, Spatial Compensation of Metrology Data

Edward West, Christopher Jamieson, Garrett Kelley

Current digital compensation techniques for uncontrolled boundary conditions such as profile at station lines and profile-per-unit-length (PPUL) fall short of accurately characterizing deformed flexible structures. Janicki Industries has developed Spatial...

David Wick

Every traditional and many emerging automotive OEMs have announced new electric powered production vehicles for sale in the next 24 months. While the powertrain architecture differs by OEM, the range, performance and cost of every electric vehicle is...

2020 CMSC PRESENTATION: An investigation into a large antenna measuring system based on total station and vision guidance

Zili Zhang

The deformation measurement and monitoring of large-scale antenna is very important for antenna users as well as manufacturers. This paper proposed a large antenna measuring method based on total station and vision guidance. Firstly, an automatic measuring...

INTEGRATION OF LASER TRACKER SYSTEM IN BIW MEASUREMENT: A CASE STUDY IN AUTOMOTIVE INDUSTRY

Armağan Altınışık, Emre Bolova

Product and process quality assurance are challenging task due to increasingly narrowing product specifications. Coordinate measurement is one of the key technologies used in the area of dimensional control to inspect and improve the accuracy of produced...

Derivation and Guide to the Uncertainty in the Angle Between Two Planes

Jana Barker, Anthony Barker

Coordinate metrologists need to plan their measurements and estimate the resulting uncertainties before data collection in order to achieve needed precisions. We present the mathematical relationship between the calculated angle between two planes, least...
