Solution to the mechanism of a screw jack
Blecha, Jan ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The presented bachelor thesis deals with the mechanism of the screw jack in terms of basic design calculations as well as in terms of production technology. The following part deals with basic division of the workshop lifting equipment, the design of the lifting device and, last but not least, the design of the production technology. Further attention is paid to the technical and economic view of the manufacturing process of the screw jack mechanism and the possibility of improving both the production process and the construction itself.

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.

Průběžné sledování opotřebení obráběcího nástroje
Veselý, Václav
The diploma thesis named Continuous monitoring of a machine tool wear deals with the issue of tool wear of machining. The thesis is divided into segments and the first segment deals with the areas of tool wear, the specific trends in the field of eliminating the tool wear and prolonging durability of tools, non-destructive test methods. These segments are a critical parts of the research, in the following part concentrates on the testing performed by the method of acoustic emission. The last part concentrates on the critical evaluation of the testing results.

Machining of rotating Body-part on CNC lathe
Dlouhý, Vít ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This master's thesis is focused on the technology fundamentals of machining for the use of the CNC lathe which was used for machining the required parts are made of stainless steel. In the introduction are mentioned the historical milestones related to machine tools. In the following chapter is analyzed machining process and related fact. A follow-up chapter contains the parameters common to a modern machine tool CNC machines. Followed by the practical part with the characteristics of the machined components. The next chapter includes a selection of CNC lathe for production. Continued by selecting the appropriate cutting tool and adjusting the machine for the given component. They were applied a total of three variants of production with the subsequent evaluation. In conclusion, it became established fact, for example, the advantages of the shape tools or the use of more spindles during the machining.

Modern cutting tools for grooving and cutting-off
Matoušek, Jan ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
The thesis in question deals with the influence of geometry of the cutting tool with a non-null angle r and of the cutting conditions on change of cutting tool’s overall deformation during the process of cutting-off and grooving. When conducting the experiments the loading of cutting tool was measured, there was created a simple 3D model of the cutting tool based on measured data, the deformation analysis of the cutting tool by the simulation programme ANSYS was performed and on the grounds of established facts there was made a conclusion on attributes of the cutting tool during the process of cutting-off and grooving.

An innovation of the CNC production of the disc-shaped parts
Křupka, Marek ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The optimal choice of cutting conditions, as well cutting tool, has a significant effect on the quality of machined part and is an essential parameter to reduce the cost of production. This thesis describes CNC turning process of disc springs made of 51CrV4 material, especially using new cutting tools and the use of higher cutting speeds. A comparison of four manufacturers of cutting tools in terms of surface quality, tool path and the machined material volume will be introduced. It was experimentally verified that our proposed facility has achieved the best result.
