Optimization of a selected manufacturing production
Kolenič, Michal ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
Táto diplomová práca popisuje optimizáciu obrábacieho procesu za účelom zvýšenia produktivity výrobnej linky. Zadanie bolo vypracované v priebehu priemyselnej stáže vo firme Stellantis na obábacej linke blokov valcov motoru DV. Práca vysvetľuje metódy analýzy strát produktivity na výrobnej linke a aplikácii opatrení smerujúcich ku zvýšeniu produktivity, obzvlásť nasadenie nástrojov štíhlej výroby. Najviac boli nasadené nástroje SMED, ktorého cieľom je optimizácia výmeny rezných nástrojov, a TPM, ktorý ma za cieľ zvýšiť spoľahlivosť výrobných prostriedkov.

Sinumerik 840D control system for programming of blanks for gear manufacturing
Havlát, Pavel ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The master thesis deals with the use of the Sinumerik 840D control system for programming of blanks for gear manufacturing. The first part of the thesis is focused on analysis of machinability of the material followed by experimental testing of machinability of material 16MnCr5. An experimental evaluation of the effect of cutting parameters was carried out to force load of semi roughing cutting tool CoroTurn 300. In the next part of the thesis there is a technical documentation of gearing parts, for which a NC program is created. Finally, the possibilities of using the Sinumerik 840D control system are listed and demonstrated by workshop-oriented programming of the considered components for the SP 280 SY turning center.

Sinumerik tools for synchronous programming of CNC machines
Toman, Martin ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis deals with advanced programming of CNC milling machines in Sinumerik 840D powerline control system. Mostly it is aimed on issues of synchronized actions. These actions can adaptively react on progress of milling process regarding to signal detection from the machine and execute specific action. In the introduction of the thesis there are briefly described basic issues and fundamentals of CNC machines and control systems programming. The problematic regarding the programming of synchronized actions is also described. The examples with evaluation of their function are created in the practical part of thesis.

Proposal for Control of Manufacture Holders of the Front Wheel for Formula Student TU Brno Racing
Vašek, Lukáš ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This thesis deals with the design and production of wheel control holders for the right front wheel of the formula Dragon 4 of TU Brno Racing team. In the theoretical part, the Formula Student competition is described, including the steering holders themselves and description of their function and location. Later the analysis of aluminium and its alloy was made, including description of the CERTAL material of which the holders were made. The practical part includes the design of prototype holders in the Autodesk Inventor CAD software, the design and application of machining strategies in the PowerMILL CAM software. Further, the practical part includes production on milling machines at the MCV 754 QUICK and DECKEL MAHO DMU 50 machining centre. At the end, the dimensional analysis of the part is performed, manufactured holders were compared to the CAD model of the given components and the technical and economical evaluation of the production was made.

Data selection and optimisation of cutting conditions for progressive production technologies
Baklík, Lukáš ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This thesis discusses a change of an existing surface grinding technology for a more effective technology of face milling for the finishing operation of the jaw (for a hydraulic machine vise) in a tempered state with hardness of 53+4 HRC. The jaw is made of tool steel according to the Czech standard CSN41 9312. Two new versions are proposed for the new technology. Progressive cutting materials are listed for milling. A suitable tool is selected. Total production costs and machine times for cutting conditions of the chosen tool are predicted. In the experimental part, the cutting conditions are verified in practice.

A proposal of production technology of a holder
Stará, Veronika ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
The bachelor's thesis deals with the analysis of the current production technology of the specified holder. The new design of the production process deals with the selection of the CNC milling center, the selection of suitable tools for machining, the selection of cutting conditions and determining the length of production of individual operations. The work includes an economic comparison of both variants of the production process.
