Course detail
CNC Technologies of Machining
FSI-9CTO Acad. year: 2024/2025 Both semester
The course is focused on advanced CNC manufacturing production. Optimal selection and strategy for machining. Cutting tools, wear and machining parameters. Time consumption and integrity of machined surfaces. Technological routes, for Sinumerik 840D/Heidenhain iTNC530 systems. Measurement with measuring and touch probes, tool compensations. Optimization of the process from the point of maximum production rate and minimum costs is solved in graphical and numerical ways. Writting of macros and special parameter subroutines.

Planned learning activities and teaching methods
Assesment methods and criteria linked to learning outcomes
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.
Compulsory and checked participations in exercises and labs.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.
Language of instruction
Czech
Aims
A study of modern CNC manufacturing technologies. Advanced programming of the Sinumerik 840D control system. Programming of the Heidenhain TNC310 control system. English terminology. Better job opportunities for graduates.
Students are trained in CNC programming and other aspects of NC machining. They will be able to define technological processes of manufacturing methods and be able to control systems using Sinumerik 840D and Heidenhain TNC 310 in English.
