Learning outcomes of the course unit

The course familiarises students with the process of checking and measuring of production machines. The objective of the course is to acquaint students with the theory and methods of measurements and application of these methods to verification of production machine accuracy.

Prerequisites

Basics of statistical data processing, basic construction nodes and elements of production machines, basic knowledge from the area of measuring of technical parameters (strength, length etc.) and processing of their results.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Course-unit credit is conditional on 100% attendance at laboratory practicals and approved reports. Examination has a written and an oral part and tests student’s knowledge and his/her ability to apply it in practice.

Aims

The course “Checking and Measuring of Production Machines” enables students to acquire knowledge of the ways of measurement performance in production machines. Students will be made familiar with fundamental terms from the area of metrology, and will have a grasp of the measurement theory and principles of geometrical and working accuracy checking of production machines.

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

1. 100% attendance at laboratory practicals
2. active participation in measurements
3. working out of reports of measurements.
Missed lessons may be compensated for by attending a laboratory practical with another study group.
