Optimal layout proposal of technological workplaces at a small mechanical engineering company
Mohorko, Martin ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
This master´s thesis is focused on technological designing in a small company ENGITEC Motosport s.r.o. In first theoretical part of the thesis is this subject described in detail and analyzed in terms of economic and technical aspect. Next part describes the current state of the company and the production hall as well with keep on its current layout. In the following chapters is chosen piston-shaped component, which is manufactured by the company and three different variants of the piston production. Then one of them is selected, to which all related capacities calculations are made. In the final part of the thesis is proposed the relevant final layout of the hall and there is also the technical-economic evaluation of the most relevant variant included. Key words

Design of a robotic workplace
Jaša, Lukáš ; Řiháček, Jan (referee) ; Štroner, Marek (advisor)
The bachelor thesis is focused on the design of a robotic workplace. In the initial phase, the input requirements of the workplace are defined, according to which the final design must be processed. Furthermore, the text contains a recherche of the current state of robotization. The third chapter is generally composed of four variants of different workplace designs. In the first of these four variants, all components are described in detail, which are also included in the remaining three designs. This variation was chosen as the most suitable possible solution. The reasons why this workplace is considered to be the most ideal are also described in detail in the chapter. In general, the robotic workplace is designed for welding steel frames of power generators. All manipulation is ensured by a welding robot together with a positioner. The operation of the entire robotized complex is performed by only one operator. In the fourth chapter, in addition to the reasons for choosing the most suitable variant, all weld lengths on the frame are calculated together with the time of complete manipulation and welding time. It also shows the time for which the designed manipulator is able to make the final product in the form of a weldment. The time for which the frame was manufactured by hand welding is also given for interest. The given results show a clear increase in production productivity in the designed workplace.

Optimization of Methods for Manufacturing Wormshafts
Černý, Michal ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The subject of this diploma thesis is the optimization of the production wormshaft under specific conditions in a particular company. The optimization was requested by firm as a solution in the areas which are defined by content of this thesis. In first part, the technology of the product manufacture is evaluated. Next analysis of the original production technology is performed the regarding rationalization explained later, proposing a new form of manufacturing process. In the following parts layout variants of workplaces are assembled. These variants are based on the newly designed technology. The final part presents a control jig, which will be used in quality assurance and manufacturing workplaces and allows to measure various type of wormshaft parts. In the discussion section there is a proposal of another possible solution for manufacturing optimization these key components that make up assembly control gearbox of valves and ball valves.

Optimum layout of pressing line for the production of reflectors at Automotive Lighting
Šťastný, Michal ; Hrbáček, Jan (referee) ; Kubík, Roman (advisor)
This thesis deals with optimization of a press line part for the manufacture of reflectors present at the Automotive Lighting Company, Jihlava. The first part focuses on describing the current workplace layout of the press line. The workplaces are located inconveniently and thus require a larger number of operators and a considerable amount of manual work. The second part of the thesis proposes layout solutions for the injection presses and for other machine parts. At the same time, a smoother transition design is proposed for the press line and for the manufacturing section that follows. Based on an evaluation of selected criteria, the optimum version is chosen, thereby adding to the efficiency of the molding process by reducing the number of operators required, by lowering the proportion of manual work relative to other activities, and by limiting the risk of poor quality. The conclusion of the thesis sums up the necessary investment costs and offers an economic assessment of introducing the selected press line arrangement to operation.

Assessment of production machine ergonomics
Klapetek, Václav ; Kotek, Luboš (referee) ; Rozehnalová, Jana (advisor)
The Master’s thesis addresses the issue of ergonomics. The aim of the diploma thesis is to analyze the current ergonomic state of the production line with the subsequent detection of ergonomic risks, the use of various assessment methods and comparison with legislative requirements. After defining the deficiencies, corrective actions are proposed, leading to their elimination and reduction of work intensity. The ergonomic analysis was performed within Tyco Electronics Czech s.r.o. The analytical part follows up on, in depth, the theoretical part of the work, where all its aspects are listed in addition to the introduction of ergonomics as a scientific discipline.
