Summary
The subject is connected with lessons form the subjects:„Mathematics,
Technology I, II, and Assembly Technology. The students adopt basic notions
and definitions of metrology, principles of complete measuring data
processing, the determination actual size for determination probability,
measuring methods, distance measurement, angle measuring, evaluation surface
roughness, measuring parts. The theoretical knowledge is practically verified
in the laboratory.
