Efficiency Improvement Proposal of Machining Process of Cylinder Component for Oil Wells
Koudela, Michal ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This diploma thesis is concerned with a proposal for increasing the efficiency of machining when manufacturing an inner sleeve at the company Sanborn a.s. In the diploma thesis, the technology used for machining itself is first briefly described, followed by a description of the original production technology including a description of machine and hand tools used and cutting conditions. The next part of the paper describes the proposal for increasing the efficiency of machining operations. The proposal includes a description of the suggested solution that will lead to increased efficiency, a machine proposed for the specific operation, appropriate tools and proposed cutting conditions. The benefits of implementing the proposal are also described here, both in terms of saving unit time, and in terms of the machining technology itself, where, for example, the formation of chips is improved, the inner tension of machined components reduced, etc. The diploma thesis further includes a technical-economic evaluation assessing the economic benefits of the changes introduced.

Project Management of Production Orders
Fiala, Ivo ; Maláčová, Markéta (referee) ; Juřica, Pavel (advisor)
The Diploma thesis deals with process improvements in project management in Alstom Power s.r.o.. The thesis is divided into three basic parts - theoretical, analytical and proposal part. The theoretical part focuses on the description of the analytical methods for examining the business environment, which will afterwards be used to analyse the current state of a company's position in the second part, analytical part, of this work. In the analytical part are identified the same errors during the project implementation. In the last part of the own proposals are presented measures that could eliminate errors and streamline process of the project implementation.

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.

The study of increase in efficiency of manufacturing preparation of technology
Šudoma, Michal ; Lána, Ivo (referee) ; Jurová, Marie (advisor)
This paper discusses different alternatives of more efficient preparation of spheroided graphite cast iron production. Secondary metallurgy and chemical heating technology are used to recast cast iron fused in copula furnace. The work applies the known physical-chemical rules used in the production of quality spheroided graphite cast iron in regular production conditions. Based on the previous developments, the aim was to prepare implementation of verified secondary metallurgy processes in adjusted casting ladle. The casting ladle was adjusted in order to allow execution of all processes required in order for the relevant standards and material lists requirements to be met in respect to spheroided graphite cast iron quality. Comments regarding the trends in ferroalloy metallurgy and related marketing approach of the company. The work is concluded by a summary of advantages brought in by the new approaches compared to the traditional ones from the economical as well as environmental perspective.

Increasing the Efficiency of the Process of Machining Injection Molds Components
Hruška, Lukáš ; Osička, Karel (referee) ; Sedlák, Josef (advisor)
The aim of this diploma work was a proposal to make the process of machining of injection mould more efficient. The work described the initial state of machining of a moulding injection part from the technological point of splinter machining, including the description of each production areas, the tool used in the process and the machines. The main part of the diploma work was focused on consideration of a possible way leading to the increase in the efficiency of the production process of machining of an injection mould part that included the transfer of the initial way of machining of a moulding injection part to CNC lathe Gildemeister CTX beta 500. Furthermore the work described the tool that had been used including the description of proposed control programs for machining of an injection mould part. The essential part of the work was a techno-economical assessment of the proposed variant of solution, which included analysis of the production costs and the time indexes that were achieved during the production.
