Coordinate metrology is inherently subject to a source of uncertainty due to an attempt to inspect an unknown surface based on a limited number of discrete observations called sampling points. The computation tasks required for this evaluation need to be designed and conducted to minimize the uncertainty factors during the inspection process. This work

Adaptive methods in coordinate metrology
SPIE Proceedings, 2005The prudent selection of the sampling points ensures that representative points to typify a feature surface are obtained. The rationale is that the larger the number of sample points, the better the estimate of the surface. Large samples however lead to large measurement times and consequently time-induced errors.

Interoperability in Coordinate Metrology
2019Coordinate metrology is an essential part of a product life-cycle management, since it guarantees the quality of component used in industrial processes. Nevertheless, nowadays industry environment is complex and full of players, which are correlated or even dependent one to another.

Computer-Aided Coordinate Metrology
13th Computers in Engineering Conference, 1993Abstract Three-dimensional coordinate metrology has gained much attention in recent years. On one hand, the accuracy and repeatability of a coordinate measuring machine (CMM) are approaching the sub-micron level. On the other hand, there is hardly any part that exists of which the dimensions cannot be measured with a CMM.

Form Assessment in Coordinate Metrology
2010A major activity in quality control in manufacturing engineering in- volves comparing a manufactured part with its design specification. The design specification usually has two components, the first defining the ideal geometry for the part and the second placing limits on how far a manufactured artefact can depart from ideal geometry and still be fit ...

Metrological Traceability of Coordinate-Time Measurements
Measurement Techniques, 2013Basic provisions for the unity of measurements in the area of coordinate-time measurements intended for construction of a national system based on advances in astrometry and the accepted international celestial and terrestrial coordinate systems are discussed.

Coordinate metrology for adaptive form verification
Manufacturing Letters, 2013Abstract Manufacturing processes leave specific patterns on part surfaces, which provide a good basis for their inspection. In this paper, machine learning and data mining techniques are applied to quantify process errors on parts and thereby provide a basis for adaptive sampling and form inspection.

Benefit quantification of interoperability in coordinate metrology
CIRP Annals, 2014Abstract One of the factors contributing to limited reproducibility of coordinate measurements is the use of different inspection software. Time-consuming efforts for translation of part programmes are sometimes needed, and interoperability of inspection equipment has the potential to reduce these inefficiencies.

Metrological Overview for Coordinate Measuring Machines
Applied Mechanics and Materials, 2015In manufacturing system, 3D Coordinate Measuring Machines (CMM) are widely used for inspection services where the product should be subjected to the verification of design specifications. It is usually necessary to know the accuracy of 3D CMM equipment during the verification process of the product quality in mass production. To insure and increase the

Discontinuity check of scanning in coordinate metrology
Measurement, 2015Abstract The paper presents a new algorithm for detecting the presence of measurement discontinuities in scanning measurements carried out on coordinate measuring machines (CMMs). The proposed algorithm marks the regions that are inaccessible to the stylus tip. This allows the machine user to decide whether to change the tip for a smaller one.
