Machining of hardened parts
 Heiserová, Sofia ; Sliwková, Petra (oponent) ; Polzer, Aleš (vedoucí práce)
The usage of quenched materials in industrial production leads to the application of hard machining. Higher requirements for machines and cutting tools are needed during hard machining than during conventional machining. Quenched materials carry problem of volume and geometric changes after quenching and after machining as well. It is necessary to think about volumetric compensation in advance, before quenching of the workpiece. An experiment is suggested for optimalisation of longitudinal turning of steels 42CrMo4 and 50CrMo4. Hard turning has notable benefits such as flexibility of cutting tools and elimination of coolants, which provides ecological benefits. However, the disadvantages are higher tool wear and high prices of tools.
