Insurance Protection of a Selected Business Entity
Pavlík, Jan ; Toman,, Petr (referee) ; Ptáček, Roman (advisor)
The aim of the master‘s thesis is to design the optimal insurance protection of a business entity. The work is divided into several parts. In the first part I deal with the methodology of work, theories and legal regulation of insurance of business entities in the Slovak Republic. In the second part, I analyze the current form of insurance protection of a business entity, I solve the risk analysis of the company and I look for the main risks of the entity with respect to its economic activity. I also analyze the current form of insurance protection and look for shortcomings or unnecessarily insured risks that the company does not need. In addition, I verify the accuracy and timeliness of all data on insurance contracts. In the design part, I will recommend the company's management to modify existing contracts and propose a new optimized insurance coverage. Taking into account the price and quality of current contracts, the possibility of modifications, extensions and newly offered products, I will recommend the continuation of existing contracts with possible modifications or entering into new contracts.

Design of spindle for a small lathe
Šatný, Patrik ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The thesis deals with the design of a headstock for a small lathe. The first part of the thesis deals with the description of individual structural nodes related to the construction of machine tools headstock. The second part includes an overview of similar machines available on the market. The final part deals with the calculation of necessary parameters, the verification of results using the finite element method and the construction of the proposed headstock. Based on the designed construction is created 3D model and drawing documentation.

Automatic tool change systems in construction of machining centers
Labounek, Dalibor ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
Automation tool change is a major factor that affects the overall level of factory automation machinery. Due to its large number of tools for machining, the system of automatic tool change (hereinafter referred to as "AVN") address one of the first questions. The help of the AVN minimize secondary production times and operator intervention while increasing productivity. With that is also linked to higher safety and minimizing human error. AVN systems expand opportunities working in the engineering industry, which is positively reflected in the price. The theme of the present thesis deals with the analysis of the problems of automatic tool change in the structure of machining centers.

Design of single-purpose machine for machining polyurethane castings
Sýkora, Petr ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
The aim of this diploma thesis is to design a single-purpose machine for machining steering wheel lever from PUR. The problem with the current state was the need of manpower for machine a large number of levers. The automated machining process eliminates the problem. The result of the work is a detailed 3D model of a single-purpose machine created in the Onshape program, drawing documentation of several parts of the equipment, economic evaluation and risk analysis of the machine. The conclusion of the thesis contains an evaluation of the whole project.

Virtual commissioning of the robotized workplace for arc welding
Adolt, Lukáš ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This diploma thesis is focused on the design of a robotic workplace for arc welding and its subsequent virtual commissioning. The summary deals with knowledge from industrial robotics and arc welding, the system analysis is focused on the composition of the workplace and the principle of arc welding, including acting influences. In the practical part, several variants of the solution are proposed, the most suitable variant is processed in the form of a 3D model. This model is then simulated, including all processes, a control program is created, and virtual commissioning of the workplace is demonstrated.
