Vibrations at machining of metals
Fiala, Zdeněk ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The diploma work deals with a mathematical description of vibration and its generation when machining. Moreover, some techniques of modal parameters measurement in the theoretical part are included. The practical part is designed and based on the measured natural frequencies of the machine with specific tool and materials. In conclusion, a lobe diagram stability for semiautomatic lathe SPN 12 CNC and selected machining operation is specified by means of apparatus.

Airconditin of delivery service
Vašík, Radek ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The aim of the bachelor thesis is to design air condition of delivery service. The theoretical part describes transmission of sound in air condition. Design of air condition is included in the practical of thesis. The design consists two air-conditioning units for air cooling and air heating. Project documentation forms last part of bachelor´s thesis.

Regenerative chatter in turning
David, Václav ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
Regenerative chatter in turning negatively affects the cutting process, the tool live and the machined surface. In this work is a vibration discriebed by using mathematical formulas or terms. There are listed some causes of creation vibration in turning and some basic methods of complete removal or partial reduction. The second part of this work contains examples of measure and analysis in connection with using of modern software.
