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.
Machining of hard materials
Pech, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The objective of this paper is to analyse the issue of machining of hard materials on Swiss-type automatic lathes at Decoleta, a.s. In the form of research, analyses are being done of the materials used, possibilities of the available cutting tools and suitable tooling materials. The current technology used in the production of two different stainless steel elements is further being analysed in detail, including the subsequent suggestion of rationalisation actions. These actions include, mainly, the design of new tools from CBN for both elements, which shall replace the current tools made of sintered carbide, but also reworking of production technology for the Pin on another more suitable type of machine, including a new CNC program and complete drawings.
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.
Technology dividing material grinding
Jermolajev, Štěpán ; Kalivoda, Milan (referee) ; Prokop, Jaroslav (advisor)
The bachelor thesis deals with the general specification of the technology of dividing materials by grinding. It describes cutting wheels and defines basic technological parameters of the cutting process with regards to relevant technical standards. Several ways of measuring or calculating some of these parameters is demonstrated on a practical issue.
Evaluation the Cost of Cutting Tools for Milling Aluminium Profiles in IFE-ČR, a.s. Company
Němečková, Monika ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This bachelor's thesis was written as part of study branch Economics and Process management on the Faculty of Business and Management in Brno. The first part is focused on the theoretical foundations. The second part contains an analysis and assessment of the overall cost of cutting tools for milling aluminum profiles in the company IFE-CR, practical analysis is based on the selected doors profile using the existing cutting tools and the newly deployed advanced cutting tools to reduce overall costs, time savings and productivity of production.
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.
On the analyses of cutiing tools coated with PVD coatings
Malý, Martin ; Osička, Karel (referee) ; Píška, Miroslav (advisor)
In this diploma thesis, literary research about drilling and coating technology focused on PVD coatings was performed. Furthermore, there is an overview of cutting materials. In the experimental part of the work, the attention is dedicated to tests of twist drills from cemented carbide and high-speed steel materials. For these drills, the feed force Ff and the cutting moment Mc were measured when drilling into austenitic stainless steel. At the end of this work, the technical and economic evaluation of the practical part is presented.
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.
