Supervisor
Learning outcomes of the course unit
The output of the theoretical knowledge of geometric accuracy measurement machine tool according to applicable standards ISO 230-2, ISO 230-4, ISO 230-6, VDI/DGQ 3441 and the implementation of measurement with the measuring devices.
Prerequisites
Basic knowledge of the structure of machine tools and knowledge in the field of metrology, mathematics and physics.
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. According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.
Assesment methods and criteria linked to learning outcomes
The course is taught through lectures and consultations. The exercise is completed by the credit where credit is subject to submission protocols with the measurements, with a total possible number of 20bodů. The test consists of a written test, and this test is 80 points. The final evaluation of the course is done by adding the points of the tutorial and examination and is given according to the ECTS scale.
Aims
The aim of the course is to introduce the methods of measurement of machine according to applicable standards ISO 230-XX (VDI DGQ 3441). Students will gain an overview of the current issue of measurement of machine tools in the Czech Republic and the world.
Specification of controlled education, way of implementation and compensation for absences
Lesson is monitored in terms of participation exercises (requires 100% participation).
