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.
The course contains lectures that explain basic principles, problems and methodology of the discipline, and exercises that promote the practical knowledge of the subject presented in the lectures.
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.
Language of instruction
1., 2. Industrial internship (two weeks).
3. Basic terminology of machining. Theoretical basis of machining.
4. Physics of machining – cut formation
5. Cutting materials – steel, sintered carbides, ceramics, diamond, etc.
6. Force analysis, heat energy, residual state of stress and the other side effects of a cutting process
7. Fundamentals of technology of turning – outside and inside face
8. Fundamentals of technology of milling – plain, form, plunge milling, etc.
9. Grinding, honing, roughening, reaming .
10. Finishing methods of machining, non-conventional methods of machining
11. Productivity and economy of machining
12. Special methods of machining – HSM/HSC
13. Fundamentals of technology and assembly process control, routing
1.,2. Industrial internship (two weeks).
3.,4. Physical basis of cutting process
5.,6. Basic concept and calculation of machining
7.,8. Selected technological measurement
9. Geometry of the cutter bit
12. Tool life between successive grindings
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.
