Progressive Milling Tools
Koubek, David ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The aim of this work is to create a research on the topic of progressive milling tools, taking into account the actual state of development and milling tools . It also deals with issues directly and milling tools , including basic theoretical and conditions characteristic for this method of machining. It deals with the brief division of instruments from several technological aspects such as design , tooling materials, methods of camping and many others. One chapter is devoted to the method itself and clamping milling tools with a mechanical , hydraulic or thermal clamping system . The last section focuses on the current list of milling tools for surface and corner cutting . These tools were selected from the production of three major domestic and international companies engaged in the production of tools for milling. These companies Pramet Tools sro , CZ Seco Tools and Walter AG.

Production of working replacement part on FDM printer
Frélich, Tomáš ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor's thesis is looking into the production of a part of a cover for ignitron of motorcycle Honda CR500R. In consideration of the required function and the attributes of the desired part an aditive technology called Rapid Prototyping (hereinafter referred to as „RP“) – method FDM (Fused Deposition Modeling) was chosen. The first part of this thesis defines summary of methods RP and materials usable for these operations. The second part is focused around a design for the 3D model in a program called Autodesk Inventor 2013, the production itself, evaluation of the technology level of the construction and a techno-economic evaluation of the costs.

Technological design of a manufacturing process modernization
Vaverka, Jiří ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The topic of this thesis is to design the modernization process. The aim of this work the design of new machines for a particular component, which would replace the existing ma-chinery used in company-tion in which the component is produced. Introduction is focused on the description of the company and selected components for which it is evaluated di-mensioning, tolerance, functionality and material. The following describes the current ma-chinery engineering company and then are selected machines in two variants, which would replace the original equipment. With these new machines is a technical documentation and is evaluated modernization and environmental concerns. At the end of the re-evaluated results that modernization is beneficial or not.

Proposal production of a chain wheel with the unconventional methods of machining use
Mikeš, David ; Kubík, Roman (referee) ; Dvořák, Jaromír (advisor)
This bachelor thesis deals with the application of unconventional methods in machining (use of laser and hydro-abrasive beam) during chain wheel production. Firstly, the unconventional methods are divided according to the overwhelming effect of material separation, and then these methods are briefly described. In the second part of the thesis, you can find the technological process of chain wheel production with the usage of cutting operation method, which is followed by the assessment of production costs. Afterwards, the chain wheel is produced with the application of laser and hydro-abrasive beam. The final part of the thesis contains comparison between the unconventional methods and the conventional method of cutting operation. The comparison is based on the achieved structure of surface of the gear tooth, the production time and the economic point of view.
