Quality assurance of horizontal road marking equipment
Janáč, Ondřej ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the requirements for the quality of equipment for horizontal road marking, which is manufactured and assembled by the manufacturer. Within the philosophy of continuous improvement, this work describes a project leading to a reduction of the number of parts, that do not fulfill their function after assembly. The main benefit of the work is a proposal to modify the production documentation and change of the measuring equipment used in its inspection. All taken measures have reduced the number of defective parts. It also provides an overview and general procedure of the selection, analysis, implementation of another measures and the use of other opportunities to improve the quality management system of horizontal road markings in the company in accordance with ISO 9001.

System of On-/Offline temperature measurement based on Lab View
Stejskal, David ; Hammer, Miloš (referee) ; Prostredník, Daniel (advisor)
The objective of this thesis was to create a LabVIEW-based program for temperature measurement using a personal computer. The program allows reading and post processing of digital signal from a measuring device. This device consists of a sensor type PT100, a measuring transducer and an analog-to-digital converter with USB output. The theoretical part of the thesis deals with resistance temperature sensors, signal analysis and methods for signal processing. The practical part is conceived as a guide to the created program. This part introduces vital sub-elements of the program and describes their principle, practical use and also the operating instructions. As required by thesis assignment, practical part includes verification of the measuring device, which was performed in laboratory of Czech Metrology Institute in Brno.

Machine tool spindle quality assurance
Marek, Tomáš ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
The master thesis deals with the problem of quality assurance of headstock in a cooperating company, which is one of the leading manufacturers of grinding machine tools. The aim was to analyse the current situation and to suggest possibilities for improving the quality of the spindle. The main contribution is the introduction of control charts for individual values and a capability index to monitor the stability of selected production processes. The thesis concludes by suggesting a number of further options for improving the quality management system in the collaborating company, which should be considered by the company.

Special length sensors
Pavliš, Jakub ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
This bachelor thesis contains a theoretical description of selected length sensors with emphasis on inductive and optical sensors. The main benefit of this thesis is the design and realization of a special inductive sensor with a small pressure force and an optical sensor with a resolution of 2.5 nanometers. In the thesis are analyzed the selected metrological properties of the designed sensors and the formulation of recommendations for their practical use.

Quality evaluation of the connection of low-voltage control circuit cables
Chabiniok, Pavel ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
This master’s thesis deals with evaluation of quality of the connection of low-voltage control circuit cables, with the emphasis on quality assurance of crimps. An analysis of possible quality control methods, including a map of the crimping process, was created. Further, the thesis includes proposals for improvement of the original system. Furthermore, a proposal of non-destructive inspection system was produced. The conclusion summarizes the knowledge gained in quality control of crimping, including practical recommendations.

Improvement of company processes to assure safety of products
Zvolánková, Kateřina ; Jankových, Róbert (referee) ; Prostredník, Daniel (advisor)
The diploma thesis devotes to the process of ensuring functional safety of products in Bosch Rexroth Brno, which deals with industrial hydraulic systems. The first part introduces the basic legislative regulations concerning product safety and describes selected standards relevant to this thesis. The second part focuses on Bosch Rexroth and the current state in the field of ensuring functional safety of their products. It also includes a description of the functional safety solution of a specific project – a hydraulic try-out press. At the end of the thesis, improvements to the process of ensuring functional safety in response to the identified shortcomings are proposed.

Reducing vibration and noise of bearings
Nejeschleba, Martin ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the issue of bearings noisiness. The bearings noisiness appears as a negative phenomenon in all the mechanical devices that generate any kind of movement. Analysis of this phenomenon enables to analyse the technical condition of the bearing and predict its defects as well. The theoretical part of the thesis is devoted to the vibration diagnostics and noisiness diagnostics, which are deeply linked. The practical part of the thesis deals with the real problem of the bearing’s noisiness in the engineering company. The main asset of this thesis is a design and successful implementation of the measures, which reduce noisiness of the selected type of the bearing.
