Economical analysis of a cutting tool
Bilavčík, Jaromír ; Humár, Anton (referee) ; Prokop, Jaroslav (advisor)
Bachelor's thesis on ”Economic analysis of cutting tools“ is devoted to economic analysis the costs of acquisition and use of different types of cutting tools, whose use has a significant influence on the economy of production and, inter alia with the costs related to the quality of the final product. Analysis of the applicability of utility properties of instruments that are used in the mechanical machining was analyzed economically advantageous for the company. This criterion must take account of the company when the production technology. Another decision-making criteria should be the final product quality. For firms pursuing the cost of quality throughout the production cycle is of course due to classical periodic sharpening cutting tools - knives, it is preferable to use instruments with tip.

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.

Sharpening and producing standard tools on a CNC grinder Walter
Martinek, Petr ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor´s thesis presents a modern five-axis CNC machine HELITRNIC POWER from the company Walter Maschinenbau GmbH, which is designed for sharpening and production of rotary, cutting tools. The project provided the most commonly used types of tools, their materials and surface treatment (coating). Furthermore, there is described the production process and sharpening of tools using control software Tool Studio, when considered appropriate wheels and clamping devices. Finally, it provided an economic assessment of costly equipment.

Modern cutting tools for grooving and cutting-off
Axmanová, Hana ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The presented diploma thesis is divided into two parts. The theoretical part deals with modern catting tools for grooving and cutting-off, choice of material of catting inserts, and with types of tool wear and their classification. The second part of the thesis deals with calculation of volumetric wear of catting tool for grooving. There was measured the power load of the new and worn tool in the experimental part and the observed data were evaluated by software. The graphs of power load and volumetric wear of tool were created.
