Learning outcomes of the course unit
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.
Prerequisites
Successful completion of the subject ”Production Technologies II”, knowledge of fundamental methods of machining. Knowledge of mathematics, physics and material science.
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
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.
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.
Specification of controlled education, way of implementation and compensation for absences
According to the studied topic some lessons will be practicals – 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.
