Subject aims expressed by acquired skills and competences

Develop knowledge of the fundamentals of metrology, to meet the basic legal document in the field of Metrology - Metrology Act, as amended by Act No. 119/2000. Develop and apply knowledge from the baseline parameters of machine parts on specific tasks. Statistically evaluate the measured data - express the uncertainty of measurement, the measurement result. Read workshop drawings of machine parts from control perspective.

Summary

The subject belongs to a group of professional courses, which links to articles mathematics and statistic. Students will learn the basic terminology in metrology, fundamental principles of measurement, basics of data processing. Develops in-depth methodology for measuring length, plane angle, surface roughness evaluation, control selected parameters of machine parts. Theoretical findings are verified in practical exercises in the laboratory.
