Metody zapewnienia jakości technologicznej na przykładzie gwintu

Zawada-Tomkiewicz A., Wierucka I.

Mechanik

2015

R. 88, nr 8-9CD2

515--523

Przedstawiono metodę zapewnienia jakości technologicznej wyrobu na przykładzie wykonywania gwintu. Kolejno omówiono ograniczenia w procesie pomiarowym gwintu oraz możliwości zapewnienia jakości w procesie przygotowania produkcji oraz procesie wytwarzania.

A product technological quality assurance method has been presented on the example of thread cutting. Subsequently, the limitations of the thread measurement process and the possibilities of quality assurance in the production preparation process and the manufacturing process were discussed.

Comparative analysis of methods of hardness assessment

Czarski A.

Archives of Materials Science and Engineering

2009

Vol. 40, nr 2

94-97

Purpose: The aim of this paper is to show how it could utilize the statistical methods for the process management. Design/methodology/approach: The research methodology bases on a theoretical analysis and empirical researches. A practical solution is presented to compare measurements methods of hardness and to estimate capability indices of measurement system. Findings: Measurement system analysis (MSA), particularly theory of statistical tests brings correct results for the analysed case. Research limitations/implications: Comparative analysis of measurement methods - interlaboratory studies, delivery control etc. is necessary in the interpretation of results. Practical implications: Described methodology and results can be employed in the industrial practice. Originality/value: The complete statistical comparative analysis of methods of hardness measurement with the help of a stationary and mobile hardness tester.
