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.

Technology Design of a Selected Part and Application of the Designed Changes in the Manufacturing Process
Turčín, Jiří ; Jaroš, Aleš (referee) ; Slaný, Martin (advisor)
This master thesis deals with a design of technological process description for a mechanical engineering part called „pressure plate“. The component is analyzed in regards to its mechanical engineering design and used material. Some brief theoretical prerequisites for an effective solution of the problem are summarized in the paper. A detailed research of current technological methods is provided, together with an analysis of the State-of-the-Art in manufacturing, introduction of technological possibilities of the company and a timeline records of the manufacturing process. In regards to the current methods and technologies, changes to the technological process are applied. Among these changes is a unification of machinery used in the process. This leads to an innovation of the methodology and the ways to clamp the component. Other applied alternations focus on a stabilization of the drilling process, which is reached by a choice of new tools and adjustment of cutting parameters. Furthermore, a variable coding of tools in case of automatic tool change is designed. This paper then provides two possible solutions based on proposed changes and alternations. These solutions, together with the tools mentioned, are subjects to a techno-economical assessment.

Production technology of a part
Vlach, Jan ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
The aim of this bachelor’s thesis is to suggest a suitable technological process of producing the given piece. This piece is the bottom shaping piece of an injection molding form, which is further used in producing plastic cartridges for the electrotechnical industry. Milling and drilling methods will be used in production. The technological processes will take place on a console milling machine and a CNC milling machine, for which an NC program is made using WORK NC software. One the basis of the manufacturing of the given piece and analysis of the machining times; a technological procedure including recommendations for improvement is chose.
