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.

Safety of a selected production node of an automated body production line
Plachý, Štěpán ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This master’s thesis deals with the safety of a selected production node of an automated body production line. The first part is focused on a recherche of relevant directives by the Council and the European parliament. Follows a systems analysis of a solving issue and description of the production line. In the next part of the thesis, there is an accomplished analysis of harmonized standards in the safety of the production line. Furthermore, there is made hazard identification, risk estimation and risk assessment. The last part of the thesis is focused on a variants creation of safety of a workplace, technical-economic consideration of variants and computations for a final variant of the workplace.

New Concept of Car Headlights Test Fixtures
Melničuk, Petr ; Blecha, Radim (referee) ; Knoflíček, Radek (advisor)
The subject of this diploma thesis is designing a way of substituting pneumatic drives with electrical actuators for mechanical movements in a headlights tester. The thesis also contains a theoretical introduction to the issue in the first part. Substitution variants are assessed considering chosen parameters and evaluated using multi-criteria evaluation method. Two final designs are compiled based on the evaluation results and processed into the 3D model of the tester. Drawings are produced for these solutions. In conclusion, a recommendation derived from achieved results is given to the tester manufacturer, ELCOM a.s.

Safety assessment of operator activities for WHN 13 CNC horizontal boring machine
Nohavica, Radek ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma’s thesis deals with the current state of requirements for products resulting from directives of the European Parliament and the European Council. The aim of the thesis is a system analysis of the issue, proposal and justification of the chosen procedure for solving the objectives. Furthermore, the analysis of requirements of current standards and safety analysis related to the work of machine operators in the areas of operation, service and maintenance of horizontal boring machine WHN 13 CNC. The analysis is followed by a proposal for preventive measures for hazards where the value of risks and criticality is unacceptable, leading to their reduction.
