Course Description

In this course, students gain knowledge about the possibilities of using computers in production, with an emphasis on programming CNC machine tools. Students will master the basics of CAD modeling, manual programming and programming in CAD / CAM systems, especially the application of CAD/CAM systems in the design and manufacture of complex parts in biomedical engineering. They will get acquainted with the application of computers in CMM machines, robots, transport systems, storage, and the needs and possibilities of integration of production equipment using programmable logic controllers-PLC.
