Machining of quenched steels
Kosmák, Jaroslav ; Zemčík, Oskar (referee) ; Chladil, Josef (advisor)
Diploma thesis deals with machining of hardened steels. In the introductory section it is described the physical process of cutting and basic used technologies of machining. The next chapter provides an overview of cutting materials. Other chapters deal with the workpiece material and heat treatment. Furthermore, there is made a comparison of the cutting conditions while machining of hardened steels by tools from selected manufacturers. As the conclusion there is the economic evaluation.
