Course detail
Technology of CNC Machining
FSI-HNC-AKAcad. year: 2023/2024
The course is focused on the fundamentals of CNC manufacturing production. A basic guide is provided giving the grades and use of cutting materials, workability of materials. Optimal selection and strategy for CNC machining or assembling technology. Shop quality evaluation. Basic CNC technologies such as turning, milling and drilling for Sinumerik 810D/Heidenhain iTNC530 are described. Cutting tools and machining parameters. Time consumption and integrity of machined surfaces. Optimization of the process from the point of maximum production rate and minimum costs is solved in graphical and numerical ways.

Entry knowledge
Successful completion of the courses “Production Technologies II”, “Technology of Production and Computer Support of Technology”, good knowledge of fundamental methods of machining.
Rules for evaluation and completion of the course
Examination consists of a written and an oral part. The written part focuses on a solution using CNC programming and machine tooling and settings. The oral part tests student’s knowledge of a topic selected randomly from the concerned areas to assess depth of understanding of the studied processes.
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 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. Assessment of student aktivity in training cources (lab/classroom).
Successful completion of two knowledge tests on the subject.
Successful defence of their written works, protocols or technical reports.
