Streamlining of the production of a component into the aircraft engine
Bula, Tomáš ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The thesis deals with innovation of the technological process of casting called Fan support in the company Honeywell Aerospace Olomouc s.r.o. The first part of the thesis is dedicated to component description which is made of titanium alloy Ti-6Al-4V. The section is also devoted to jet engine TFE 731, which is the engine where our particular component has specific function. Another part is focused on theoretical analysis of material characteristics of titanium alloys and their machinability. In the following section there are considered alternatives of machine suppliers with subsequent selection of the multifunctional CNC milling-turning center DMC 80 U duoBLOCK equipped with Jetstream technology. The transfer of the production to another machine is accompanied by an innovation of the technological process, making new fixtures and optimalization of the cutting tools. The section is also dedicated to static analysis of the component in operation 7 supported by finite element method (FEM). The final part of the thesis includes evaluation of the costs and savings achieved by innovation of the technological process.

Control of 3-axis PCB drill
Kresta, Martin ; Dvořáček, Martin (referee) ; Macho, Tomáš (advisor)
This thesis is focused on design and realization of 3-axis PCB drilling machine. Design comes from mechanical construction of inkjet printer and reusing most of original actuators. This thesis is mainly focused on design of control electronic circuits and software equipment. The whole machine is controlled by 8bit AVR microcontroller ATmega64. Machine is also equipped with USB interface for communication with PC application. This feature allows automatic processing of CAM files from PCB design systems.

Spline interpolation in CNC milling
Soukupová, Veronika ; Píška, Miroslav (referee) ; Ohnišťová, Petra (advisor)
Tato práce se zaměřuje na využití různých typů splinové interpolace pro obrábění na číslicově řízených strojích. Cílem této práce je teoreticky popsat využití splinových interpolací při CNC frézování a následně stanovit a zhodnotit limity využití různých typů splinových interpolací na základně daného objemu vstupních dat. Součástí práce je vytvoření programu pro generaci různého počtu uzlových bodů na analyticky známé křivce. Následuje vložení uzlových bodů do vytvořeného CNC programu pětiosého obráběcího centra a poté jeho verifikace. Pro stejné uzlové body jsou aplikovány různé druhy interpolace pro následné porovnání metod a stanovení minimálního počtu bodů na délku křivky pro dosažené vyhovující přesnosti při použití dané interpolační metody.

Draft of pin production technology
Hrdlička, Martin ; Osička, Karel (referee) ; Jaroš, Aleš (advisor)
The Master's thesis, written during the study of M-STM Manufacturing Technology and Management in Industry, is focused on the concept of the production technology of a pin. The thesis includes a description of forming and machining technology in terms of possibilities of their application in the production of the pin. Furthermore, by comparing both technologies and preliminary economic evaluations of production, it leads to the choice of the production method. This production method is then described, and the description contains the production process steps including the creation of the CNC program. The conclusion of the thesis is devoted to the technical and economic evaluation of the production concept.
