Design of a combined tool for holes machining of the universal chuck
Kovář, Matouš ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This master’s thesis focuses on the design of a combined tool for machining holes of a universal chuck. The thesis analyses the component and technologies used for the production of precision holes for pinions in the chuck body. Furthermore, the current production of precision holes is described, including the used machine, tools, cutting conditions and technological process with machine times. In the next part of the thesis, a proposal of more efficient production of precision holes is made accompanied by a design of a combined tool. The design includes its structural treatment, used cutting tool inserts and drill, the method of clamping, used material, the heat treatment, the determination of the cutting conditions and the development of a new technological procedure. The thesis concludes with a technological and economic evaluation, where the existing and the newly proposed technologies for the production of precision holes for pinions in the chuck body are compared.

Design of lathe chuck with machine-adjustable excentricity
Petrych, Jan ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
This master´s thesis focuses on constructional design of chuck with settable eccentricity in two axes. The first part consists of brief analysis of the clamping of CNC machines and summary of available chucks with settable eccentricity. Next part deals with study of possible construction designs. Two construction variants will be based on those designs in the next part. Following part then describes dimensionality of the main parts of the chuck. Based on the calculations, the 3D model of chosen variant is created with the description of its functionality. Finally the conditions of operation for the chuck are described.
