Developing engineering ontology for domain coordinate metrology [PDF]

open access: yesFME Transactions, 2014
Already developed and applied engineering information, it is often stored and forgotten. Current approaches for information retrieval are not effective enough in understanding of engineering contents, because they are not developed to share, reuse and ...

Assumptions of the digital twin in coordinate metrology

open access: yesMeasurement: Sensors
Coordinate metrology, or measurement systems, are an important part of Industry 4.0 and 5.0, which result in a range of data recorded for all production departments. The data can be used not only for inspection, but especially for prediction in the production cycle.

An Optical Coordinate Measuring Machine for Nanoscale Dimensional Metrology

open access: yesJournal of Advanced Computational Intelligence and Intelligent Informatics, 2004
Coordinate Measuring Machines (CMMs) are commonly used for geometry verification and replication on solid parts and work pieces on many scales. As the parts predicable continues to grow smaller and smaller, so grows the need to accurately measure the dimensional accuracy of these parts.

Application of Coordinate Measuring Arm for Accurate Measurement of Child Growth

open access: yesMeasurement Science Review, 2018
The article describes an approach to measure child growth using a coordinate measuring arm. For this purpose, a test set up has been built to measure the lower leg length directly on the knee surface and with the help of a plate.

Coordinate Transformation Uncertainty Analysis in Large-Scale Metrology

open access: yesIEEE Transactions on Instrumentation and Measurement, 2015
3-D coordinate transformation, which is based on aligning two sets of common reference points, is frequently applied in large-scale combined measurement to unify coordinate frames and tie individual measurement systems together. However, it introduces uncertainty into the final measurement results.

A combined alignment technique for mid-spatial frequency error suppression in ion beam figuring of aspheric mirrors

open access: yesResults in Engineering
The deterministic correction of mid-spatial-frequency (MSF) errors on complex aspheric surfaces is highly sensitive to coordinate consistency between the target surface error and the actual material-removal position.
