Course detail
Technology of CNC Machining
FSI-HNC-AAcad. year: 2016/2017
The course is focused on the fundamentals of CNC manufacturing production. A basic guide is provided giving the grades 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.
