| Summary |
|---|
The subject belongs to a group of professional courses, which links to articles Mathematics, Technology machining. 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.
