Course detail

Technology of CNC Machining

FSI-HNC-A Acad. year: 2024/2025 Winter semester

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 840D/Heidenhain iTNC530 are described. Cutting tools and machining parameters. The work with measuring and touch probes, measurement of tool compensations. 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.
