Production of herringbone gears on FDM 3D printer
Čada, Jiří ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
This bachelor's thesis deal with an issue of manufacturing herringbone gears by Fused Deposition Modeling method. It focuses on manufacture of the gear by using FDM printing and compares it with using conventional methods from technological and economic perspectives. The gears are designed and modeled with respect to the abilities of FDM printer depending on the preservation of the components small size.

Solution technology of adjustable V-belt pulley
Láznička, Pavel ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
At the beginning, the thesis contains description of belt drives and balancing of an adjustable belt pulley. The topic of the next chapter is concerned with the evaluation of technological aspects of unit and series production. It is followed by a choice of material, a semi-finished product and a calculation of material consumption. A technological procedure with selection of machine tools and selection of suitable method of production with calculations of a producing time are described afterwards. At the end, the ecological aspects are assessed. The conclusion comprises technological and economic evaluation of production.

Dynamic characteristic of the workpiece in turning
Nádvorník, Vít ; Štetina, Jakub (referee) ; Fiala, Zdeněk (advisor)
The contens of master thesis is theoretical analysis of vibrations during turning and possibillity to eliminate them, measure dynamic compliance and modal paramteters. The goal of experimental part is to determine the effect of material and type of clamping for three shafts at natural frequency, mode shape and dynamic compliance. Using these results we can optimized cutting parameters and to better overcome vibration during machining.

Analysis of the coated carbide cutting inserts
Zdráhala, Radim ; Kolář, Ladislav (referee) ; Fiala, Zdeněk (advisor)
Bachelor thesis is focused on the analysis of the cutting and specific cutting forces during face milling of coated and uncoated exchangeable cutting inserts (VBD). The theoretical part deals with the characteristic of the milling process, coating of cemented carbides and last but not least deals with methods for measuring cutting forces. The experiment is described in the experimental part that also includes evaluation of load forces coated and uncoated exchangeable cutting inserts during changes in cutting conditions. Finally is performed the comparison of values coated and uncoated VBD for flank wears and load cells.

Regenerative chatter in turning
Sucháček, Roman ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
This bachelor´s thesis deals with the vibrations produced during turning. Several principles of these vibrations formation are. This includes regenerative principle and the principle of position feedback. Vibrations are caused by the mutual vibration of workpiece and the tool, with the result that occurs corrugated surface of the workpiece, during the first revolution of workpiece, which also regenerates the vibrations. Vibrations are the most affected by the width of the chip and the workpiece speed. Based on measurements and calculations is drawn stability lobe diagram. The diagram determines the maximum width of the chip, or the maximum speed, for which it is possible to cutting ithout any vibrations.

A new production technology of a rotational part
Sychra, Jiří ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
This master’s thesis is focused on a new production technology of a rotational part. The SolidWorks software was used for create the component design. According to the proposed models, CNC program using parametric programming using mathematical functions was created in the CNC Syntax Editor Free Edition program. The final step was the experimental verification of the functionality and components compared with other type and the economical evaluation of manufactured components.
