Subject aims expressed by acquired skills and competences
The goal is to define the initial characteristics of the machining process, cutting patterns of HSC and its ways. Further accesses to the parameters of HSC milling machines, and physical and mechanical properties of super-cutting "materials. Analyzes in detail the various aspects of high-speed machining and compares the deformation and contact zones "and the conventional HSC technology.
