Safety assessment of an operating Haas VF-2SSYT machining centre
Hochman, Jan ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This thesis focuses on the safety assessment of a CNC machining centre. In the introductory part the current requirements of the European Union and Czech legislation are summarized. This is followed by a systematic analysis of the issues and an analysis of good engineering practice. The second part of the thesis is devoted to the safety assessment of the production equipment itself. On the basis of checklists, potential risks are identified, which are subsequently analysed and evaluated.

Safety of workpiece clamping device
Mahel, Petr ; Bradáč, František (referee) ; Blecha, Petr (advisor)
Master’s thesis is dealing with safety of workpiece clamping device. In the first part we are describing possibilities of clamping workpiece on different machines, legislative conditions in EU and CR in engineering devices, and general demands that refer to harmonized standards for different types of clamping devices. The main target of the thesis are the lists of requirements for hydraulic three-jaw chucks and proposal of two chosen safety applications. The first safety application refers to safety of clamping workpiece in hydraulic chuck. The second safety application is aimed at clamping of workpiece with the help of strap clamps. There is a description of the procedure of calculation of safe tightening moment during assembly of the nut.

Safety assessment of a multifunctional machining centre
Šponiarová, Petra ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The thesis deals with the safety of the multifunctional machining centre of TOS KUŘIM – OS, a.s. In order to assess the safety of the multifunctional machining centre and the safety of the workers involved in its manufacture and assembly, it was first necessary to familiarise ourselves with all the legislation, which includes EU harmonisation and OSH legislation. Harmonised legislation is followed by harmonised technical standards. Compliance with the basic safety requirements of the relevant harmonised standards is a prerequisite for meeting all the requirements of harmonisation legislation. One of the basic requirements before placing a product on the EU market is to carry out a risk analysis. This has been done by correcting and supplementing the risk analysis of the milling machining centre, on whose design the analysed machining centre is based, to meet the requirements of ČSN EN ISO 12100:2011. Particular attention was paid to the production and assembly stage, where several standard production and assembly procedures were selected. Flow charts were drawn up for these selected procedures and a risk analysis was carried out using the FMERA method, which was developed by modifying the FMECA method. For each risk, measures were proposed to ensure that it was reduced to an acceptable level.

Contemporary technology of clay bricks production - possibilities and perspectives
Polláková, Lenka ; Pavelka, Oldřich (referee) ; Sokolář, Radomír (advisor)
In the theoretical part, this diploma thesis deals with brick production, basic raw materials for brick production and the technological process of production itself. It also focuses directly on the fired brick, its legislative requirements and manufacturers who currently produce this brick in the Czech Republic and Slovakia. The possibilities of current manufacturers are assessed in the practical part, especially in terms of salinity, mineralogical composition and behavior during firing of their production mixtures. As last the optimal firing temperature of the available mixtures is designed to achieve ideal parameters as frost resistence, strenght, appearance etc.

Prozessbeschreibung zur Integration von Ecodesign und Maschinensicherheit in den Produktentwicklungsprozess
Božek, Alexandr ; Prostredník, Daniel (referee) ; Blecha, Petr (advisor)
Diplomová práce řeší problematiku vzniku nových požadavků, které jsou kladeny na vývoj nových výrobků s ohledem na budování nízkouhlíkové ekonomiky a zvýšení bezpečnosti výrobků. V první části diplomové práce je popsán stav vědy a techniky v oblasti procesního řízení a následně je popsán životní cyklus obráběcího stroje, s důrazem na vývoj stroje. V druhé části je provedena rešerše v oblasti legislativních požadavků na bezpečnost stroje a na ekodesign stroje do vývoje. V praktické části je provedena analýza hlavních procesů firmy produkující výrobní stroje, a to s důrazem na procesy v oblasti bezpečnosti a ekodesignu. Následně jsou navrženy procesy pro stanovení a ověřování bezpečnosti. Dále práce popisuje metodiku implementace ekodesignu do procesů firmy, která je prezentována na procesech firmy a demonstrována na jednoduchém příkladu vrtačky. Diplomová práce má tak praktický přínos v zavedení subprocesu stanovení a ověření bezpečnostních požadavků a zavedení procesu vývoje produktu v rámci realizace ekodesignu na produktech firmy.

V první části diplomové práce je popsán stav vědy a techniky v oblasti procesního řízení a následně je popsán životní cyklus obráběcího stroje, s důrazem na vývoj stroje, spolu s požadavky a doporučeními ISO 9001:2016 – Systémy managementu kvality – Požadavky. V druhé části je provedena rešerše v oblasti legislativních požadavků na bezpečnost stroje a na ekodesign stroje do vývoje. V praktické části je provedena analýza hlavních procesů firmy TOS KUŘIM – OS, a.s., a to s důrazem na procesy v oblasti bezpečnosti a ekodesignu. Následně jsou navržena zlepšení procesů, do nichž jsou aplikovány subprocesy na stanovení a ověřování bezpečnosti. Do procesů je aplikován subproces umožňující produkci strojů plnících požadavky ekodesignu. Diplomová práce má tak praktický přínos v zavedení automatizovaného subprocesu stanovení a ověření bezpečnostních požadavků a zavedení subprocesu vývoje produktu v rámci budoucích požadavků ekodesignu na produkty firmy TOS KUŘIM – OS, a.s.
