Cemented carbides and theirs effective use
Crhan, Luboš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Bachelor's thesis is elaborated in an bachelor's study program B2341 - Engineering, branch of Engineering Technology at the Faculty of Mechanical Engineering in Brno. Work is focused primarily on issues of cemented carbides cutting tools and their effective use during machining. The first chapter describes basic informations on distribution, labelling, raw materials, manufacture, properties of cemented carbides, etc., from literary sources. Other chapters are devoted to evalution and comparsion of cutting conditions for different types of tool materials from different manufactures.

Production technology for part of metal cuting machine.
Kachyňa, Stanislav ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This thesis deals with design for manufacturing technology single part on machine FS, which is the connecting part. Work deals with the material of this component, therefore, cast iron with lamellar graphite, the properties of this material, primarily focusing on the machinability. Due to the shape and dimensions of the workpiece is also described problems cutting of box parts, the most common operations used in their manufacture, including cutting tools and materials. These findings are then applied in terms of the company TOS Kuřim - OS a.s. An analysis of current manufacturing technology and design is made for its amendment. In conclusion with the technical-economic evaluation.

Advanced technology project of valve body
Štábl, Martin ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This diploma work is dealing with the progressive production technology proposal of the valve body type S43 components. This is the high-pressure valve for the classical power supply. Here in the work is described the structural design of the valves, the material of the valve body and its machinability. Following an analysis of the existing production technology is the new production technology proposal for this part. All is designed with regards to the business possibilities of the Armaturka Vranová Lhota company. In conclusion of the work is presented the technical economic evaluation of both the existing and the proposed manufacturing technology.

Machining of polymericMaterials
Ondráček, Ivo ; Němec, Karel (referee) ; Molliková, Eva (advisor)
This bachelor’s thesis deals with the machining of polymeric materials and the major differences between the machining of metals and polymers or plastics. Introduction describes the basic elements in the history of the discovery and use of plastics. The thesis focuses on the basic division, further definitions and internal structure of the polymers. There are also discussed the most widely used machining technology and requirements for tools and materials. At the end of the work we are specified properties and selected types of plastic materials intended for processing. Practical informations were obtained during the visit to Brno company Belt Plast, Ltd.

Rationalization of machining technology
Plančar, Jakub ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis is focused on a design of rationalization solutions for machining workplace in Siemens Company. The machined pieces are shafts, the basic components of the electric motors. The introductory part of this study describes the theoretical basics of machining technology, especially milling. The next part is focused on the company presentation, the analysis of the existing workplace and its technologies and components. In the following section are selected weaker production sites, and then is presented opportunities for improvement and rationalization of this workplace. Following the elaboration of the selected rationalization solution, along with techno – economic evaluation of the production change, which highlights the results of this study.

Design of component production using turning technology
Surovčák, David ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
This work analyzes an existing shaft design and design of a new construction and technology of this shaft for a particular series. It solves the ideal semi-finished product, the choice of a suitable machine for this particular technology, and the choice of tools for this production. The shaft is further checked for ultimate strength. It includes the production process and production guides. For turning technology, I also calculated an economic evaluation.
