Entry knowledge

Knowledge of fundamental methods of machining. Knowledge of mathematics, physics and material science.

Rules for evaluation and completion of the course

Examination consists of a written and an oral part. The written part is focused on the solution of a technological problem. The assessment reflects student´s professional skills. The oral part tests student's knowledge of a topic selected randomly from the concerned areas to assess the depth of understanding.
Recommended participations in lessons. Compulsory and checked participations in exercises and labs. Obligatory full presence in all exercises. Inspection of senior professors. According to the studied topic some lessons will be practical - carried out in the lab, and some will be focused on the theory - calculations carried out in the classroom in a seminar form. Absence from seminars should be substituted for by attending a seminar with another study group or individually by the agreement with the teacher. Lessons may be occasionally inspected by the head of the department. Successful completion of two knowledge tests on the subject. Successful defence of their written works, protocols or technical reports.

Aims

The aim of the course is for students to master fundamental machining technologies based on the principles of physical and chemical interactions of the machine-workpiece-tool system. In addition, manufacturing assembly and other concerned disciplines are dealt with. Students will be familiar with physics and other aspects of machining. They will be able to define technological processes for all fundamental manufacturing methods and will have an overview of principles applied for technological assembly.
