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.

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

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

The student’s own work and knowledge is assessed in practicals. 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.
