An investigation of outlier detection procedures for CMM measurement data
Chelishchev, Petr; Popov, Aleksandr; Sørby, Knut (Journal article; Peer reviewed, 2018)The paper analyses methods for outlier detection in dimensional measurement. The cross sections of an internal cylinder were inspected by CMM (coordinate measuring machine), and received data sets were employed for further ... -
Estimation of minimum volume of bounding box for geometrical metrology
Chelishchev, Petr; Sørby, Knut (Peer reviewed; Journal article, 2020)This paper presents algorithms for estimating the minimum volume bounding box based on a three-dimensional point set measured by a coordinate measuring machine. A new algorithm, which calculates the minimum volume with ... -
Optimization of Sample Size for Two-Point Diameter Verification in Coordinate Measurements
Chelishchev, Petr; Sørby, Knut (LNEE;volume 484, Journal article; Peer reviewed, 2019)This paper investigates the possibility for reduction of sample size for inspection of two-point diameters with a coordinate measuring machine, by use of statistical methods. The statistical methods implement the parametric ... -
Robust estimation of optimal sample size for CMM measurements with statistical tolerance limits
Chelishchev, Petr; Popov, Aleksandr; Sørby, Knut (Journal article; Peer reviewed, 2018)The paper proposes the kernel probability density function approach to estimate the distribution of measurements on a part which is measured in a coordinate measuring machine (CMM). The study is based on the experimental ... -
Sample Strategies, Data Processing and Algorithms for Coordinate Measurements
Chelishchev, Petr (Doctoral theses at NTNU;2020:259, Doctoral thesis, 2020)The PhD thesis proposes new approaches and algorithms related to the field of Geometrical Dimensioning and Tolerancing (GD&T) inspection based on ISO standards on Geometrical Product Specifications (GPS). The main purpose ... -
Simulation Algorithm of Sample Strategy for CMM Based on Neural Network Approach
Chelishchev, Petr; Sørby, Knut (Chapter, 2020)This paper proposes the algorithm for analyses of sample strategies. The back propagation artificial neural network approach is employed to approximate CMM measurements of the circular features of the aluminum workpieces ...
