Subject aims expressed by acquired skills and competences
In this course students are introduced to the basic measurement methods. Virtually try to evaluate the measured data. Passing the course Metrology to increase their skills and acquire the work of many measuring devices. They will also learn to work with data obtained by measurements.
Teaching methods
Lectures
Experimental work in labs
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.
