Learning outcomes of the course unit

After completing the course, the students will acquire knowledge and skills in metrology, that is, they will learn how to measure and check various geometric quantities and use adequate methods to check the precision of the measurement. The measurement will focus on lengths, diameters, surface quality, angles, cones, etc. using common means of metrology but also computer-aided state-of-the-art methods.

Prerequisites

Bases university mathematics. Bases mathematical statistics. Legislative metrology. Workshop chaining. Meridla sliding with micrometrical. Verification gauge. Basic concepts international dictionary metrology. Verification in engineering company. Bases theory mistakes metering.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

To receive credit in a seminar, a student must attend the required seminars, work out all the practical laboratory assignments, submit the reports on the experiments conducted and meet all the requirements of ongoing supervision (written tests of knowledge for particular seminars). If the attendance and ongoing supervision conditions have not been met, in well-justified cases, the supervising teacher may require the fulfilment of a substitute condition.
Examination: An examination consists of a written and an oral part. It verifies whether a student has learned the theoretical basics and their practical applications. The exam results also reflect those of the practical laboratory exercises, the experiment reports and the written tests.

Aims

The course aims to acquaint the students with the essential legislation concerning quality and metrology with a view of the present European integration so that they can approach particular practical problems at the required level. As a result of acquiring theoretical knowledge in the course, the students should have an overall understanding of the practical issues of measurement and inspection of engineering products, particularly when evaluating geometric quantities.

Specification of controlled education, way of implementation and compensation for absences

If a student cannot attend a seminar on the required date, he or she may attend a substitute seminar with a different study group in the same week. If this is not possible (due to an illness or for a similar reason), he or she will submit an additional report or an assignment according to the instructions from the supervising teacher.
