Vibration at machining of metals - reasons and remedies
Sismilich, Vladimír ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
This diploma thesis is concerning about summarizing and describing types of vibrations, their causes and influences to the machining. The stable conditions of machining were pointed out. The experiment was conducted in which the frequency response function of specific milling machine was measured. Than the stability lobe diagram was constructed.
Vliv vlhkosti na velikost řezné síly při obrábění nativního dřeva
Skokan, Vojtěch
This bachelor's thesis deals with the influence of water content in wood on the energy parameters of oak wood machining. The main parameters under research were cutting force and specific cutting resistance. The results of experimental measurement of these parameters were compared with the results of theoretical calculation methods, Technological-statistical and Analytical methods. The results and statistical tests carried out determined the effect of moisture on the size of the cutting force and specific cutting resistance. In conclusion, the values of the cutting force increase with increasing humidity to FSP, and as humidity increases above FSP, the values decrease. The specific cutting resistance increased to FSP as the moisture of the patterns under viewed increased and decreased as humidity increased further above this limit.
